Liu, L. Y. and Li, H. 2013. Review: Research progress in amur grape, Vitis amurensis Rupr. Can. J. Plant Sci. 93: 565-575. Vitis amurensis Rupr., which originates in China and has several important traits, such as cold- and disease-resistance, is now commercially cultivated in China. Vitis amurensis has a strong root system and high growth vigor allowing it to survive temperatures as low as -40°C without the need to bury its vines, saving inputs in vineyard management. During growth, V. amurensis vines have high resistance to many diseases, such as grape white rot and grape anthracnose, and are thus often used as a disease-resistant stock as well as the most powerful cold-resistant rootstock to breed materials for novel cultivars. As a wine grape, the fruit fragrance and distinctive taste are unique for making high quality red and sweet wines, which have a brilliant ruby red color, fine fragrance, and a full-bodied and distinctive taste. Vitis amurensis grapes and the wines made from them contain abundant bioactive natural substances, which have important effects on lowering human blood pressure, antioxidation, anti-aging, cardiovascular disease prevention, etc. The present article addresses research progress and the utilization of V. amurensis achieved in the past decades. Further studies are proposed.

Harker, K. N., O'Donovan, J. T., Blackshaw, R. E., Hall, L. M., Willenborg, C. J., Kutcher, H. R., Gan, Y., Lafond, G. P., May, W. E., Grant, C. A., Barthet, V., McDonald, T., Wispinski, D. and Hartman, M. 2013. Effect of agronomic inputs and crop rotation on biodiesel quality and fatty acid profiles of direct-seeded canola. Can. J. Plant Sci. 93: 577-588. A field study was conducted at eight sites in western Canada to determine the influence of agronomic inputs on fatty acid profiles and biodiesel quality of canola. Protein and chlorophyll concentration and fatty acid profiles were determined from seed samples at all sites. Oil was extracted from canola seed samples from three sites, converted to biodiesel, and subjected to standard protocols. Protein concentration increased at higher than recommended rates of nitrogen (N) and the higher canola seeding rate (150 seeds m^-2) reduced chlorophyll levels in canola oil. All biodiesel samples fell below new oxidation stability tolerance levels (minimum 8 h). However, given the routine addition of commercial antioxidant additives, all biodiesel samples from this study were suitable for blending in middle distillate fuels. Cloud point values were lowest at normal N (1×) rates. Normal N rates increased stearic acid content, whereas high N rates (1.5×) increased gadoleic acid content. Low seeding rates (75 seeds m^-2) increased palmitic acid content. The combination of normal N (1×) with a high seed rate (150 seeds m^-2) increased oleic acid content. Conversely, the combination of high N (1.5×) with a low seed rate (75 seeds m^-2) increased linolenic acid content. Gadoleic acid content increased in the continuous canola rotation versus the canola-wheat-canola rotation; similar trends were observed with palmitic, linoleic, and linolenic acid. Oleic acid tended to be higher in canola rotated with wheat. Cold filter plugging point (CFPP) was predicted based on saturated fatty acid content. Usually, a high seeding rate (150 seeds m^-2) combined with a normal N rate (1×) led to the most favourable (lowest) CFPP values. Low CFPP values were also associated with canola rotated with wheat compared with continuous canola production. Seeding rate, N, and crop rotation influenced protein and chlorophyll concentration, fatty acid profiles, cloud point, and CFPP.

Hansen, M. J., Owens, V. N., Beck, D. and Sexton, P. 2013. Suitability of cover crop monocultures for late-season forage in South Dakota. Can. J. Plant Sci. 93: 589-597. Cover crops provide many agronomic benefits and can produce large amounts of forage that is suitable for grazing. The objectives of this study were to determine (1) suitable cover crop forages based on yield and nutrient values; and (2) changes in feed value and yield of these crops through the late fall. Five cover crop monocultures consisting of lentil (Lens culinaris Medikus), cowpea (Vigna unguiculata L.), foxtail millet (Setaria italica L.), oats (Avena sativa L.), forage radish (Raphanus sativus L.), and a mixture of these crops were planted after winter wheat (Triticum aestivum L.) harvest in 2010 and 2011 in central and southeastern South Dakota. Forage data were collected on approximately Oct. 01, Nov. 01, and Dec. 01 each year. Yields increased after the first harvest date at both sites, both years. Oats, radish, and the cover crop mixture all yielded >4000 kg of dry matter per hectare on the second harvest date in 2011 in central South Dakota and radish and oats yielded >4000 kg ha^-1 in southeastern South Dakota on the second and third harvest dates, respectively. Forage quality tended to decrease after each harvest date. Radish in central South Dakota in 2010 had the highest protein values for the study (194-313 g kg^-1) whereas oats in southeastern South Dakota had the lowest protein concentrations (63-108 g kg^-1), both years. All cover crops except cowpea were viable forages through the late fall when they had good establishment with the potential need for protein supplementation with oats, foxtail millet, and the cover crop mixture, depending on animal requirements.

El-kereamy, A. and Jayasankar, S. 2013. Cloning and differential expression of a plum single repeat-MYB, PdMYB3, in compatible and incompatible interactions during fungal infection. Can. J. Plant Sci. 93: 599-605. Enhancing resistance to pathogen attack through conventional breeding is a major challenge, especially in perennial species. Monilinia fructicola fungal infection causes brown rot disease, resulting in economic damage of stone fruits at flowering, pre- and post-harvest stages. The molecular mechanism of resistance to this disease is still not known. In the present study, we cloned and analyzed the expression of a novel MYB transcription factor from European plums (PdMYB3) induced in response to M. fructicola fungal infection. The identified PdMYB3 is a single repeat-MYB protein that contains a conserved SHAQKYF motif. Monilinia fructicola infection induces the expression of PdMYB3 in fruits of four cultivars within 24 h; however, it is differentially expressed in the susceptible and resistant varieties. By comparing four different cultivars we found that PdMYB3 is induced in much higher levels in the susceptible cultivars than the resistant ones. In addition the PdMYB3 expression is higher in the early stages of fruit development prior to pit hardening, suggesting a potential role for PdMYB3 during this stage. Promoter analysis revealed the presence of some hormone cis-elements suggesting a possible role for PdMYB3 gene in transmitting a signal from the hormonal pathways to downstream components during host-pathogen interactions.

Beres, B. L., Cárcamo, H. A., Byers, J. R., Clarke, F. R., Pozniak, C. J., Basu, S. K. and DePauw, R. M. 2013. Host plant interactions between wheat germplasm source and wheat stem sawfly Cephus cinctus Norton (Hymenoptera: Cephidae) I. Commercial cultivars. Can. J. Plant Sci. 93: 607-617. The wheat stem sawfly (WSS) Cephus cinctus Norton (Hymenoptera: Cephidae) is an economically destructive insect pest of wheat in the northern Great Plains. A significant resurgence of the insect pest in the southern prairies of Canada caused substantial economic losses from 1999 through 2007. Solid-stem cultivar selection is critical to the management of WSS but adoption of the use of these cultivars was low, which compounded losses at harvest. A study was conducted from 2001 to 2003 in southern Alberta and Saskatchewan, Canada (1) to establish the range of susceptibility of hollow- and solid-stem varieties representing the major spring wheat classes and (2) to determine the impact of host plant on WSS population dynamics. The solid-stem varieties were generally superior at reducing damage and fitness response of WSS. However, in addition to the durum cultivars AC Navigator and AC Avonlea, the variety McKenzie, which was considered hollow, provided improved efficacy over other hollow-stem cultivars. Our study suggests solid-stem cultivars are highly effective but prone to inconsistent performance and should therefore be integrated into a holistic strategy for WSS that includes agronomics and biocontrol. A companion paper will report on the response of cultivars with novel sources of germplasm.

Chang, K. F., Hwang, S. F., Ahmed, H. U., Gossen, B. D., Turnbull, G. D. and Strelkov, S. E. 2013. Management strategies to reduce losses caused by fusarium seedling blight of field pea. Can. J. Plant Sci. 93: 619-625. Fusarium seedling blight can cause substantial reductions in the stand density of field pea in western Canada. In greenhouse experiments, emergence decreased and root rot severity rose with increasing inoculum density. In field trials in 2007 and 2008 near Edmonton, AB, seeding at different depths and seeding dates did not consistently affect emergence or yield in Fusarium-infested soils. In field experiments, emergence declined significantly with each increase in inoculum level. Also, seed yield were reduced at high levels of disease pressure. Treatment of seed with Apron Maxx improved emergence, nodulation and yield of treatments challenged with inoculum of F. avenaceum in both greenhouse and field experiments. This research demonstrates the need to prevent seedling blight and root rot through proper seed treatment.

Głowacka, K., Jeżowski, S. and Kaczmarek, Z. 2013. Gas exchange and yield inMiscanthusspecies for three years at two locations in Poland. Can. J. Plant Sci. 93: 627-637. The influence of gas exchange parameters on yields of six Miscanthus clones were evaluated in two locations over three years. Five out of six genotypes had significant increases in the photosynthetic rate and intrinsic water use efficiency between the third and first or third and second years, while intercellular CO₂ concentration and stomatal conductance decreased. In addition, the multiple regression analyses of yields on parameters showed that the type of the correlation coefficients for transpiration, stomatal conductance and intercellular CO₂ concentration varied throughout the years. The strongest correlation (0.86) between yield and photosynthetic rate was found for 3-year-old plants.

Reeh, K. W. and Cutler, G. C. 2013. Laboratory efficacy and fungicide compatibility ofClonostachys roseaagainstBotrytisblight on lowbush blueberry. Can. J. Plant Sci. 93: 639-642. Lowbush blueberry (Vaccinium angustifolium) is an economically important crop. Clonostachys rosea is an endophytic fungus that can provide protection of plants from several pathogens, including Botrytis cinerea. It is unknown if C. rosea is able to colonize and protect V. angustifolium, and whether it is tolerant of fungicides commonly used for B. cinerea management in blueberry production. In a greenhouse experiment, pre-treatment of blueberry blossoms with C. rosea significantly reduced establishment of B. cinerea, but treatments after establishment of the pathogen were not effective. Clonostachys rosea demonstrated in vitro tolerance to the fungicide Switch^®, but little or no tolerance to Pristine^® and Maestro^®. Our results are encouraging for additional field research examining the use of C. rosea as part of an integrated pest management program for B. cinerea control on lowbush blueberries.

Kegode, G. O. and Darbyshire, S. J. 2013. The Biology of Canadian Weeds. 152. Artemisia biennis Willd. Can. J. Plant Sci. 93: 643-658. Artemisia biennis Willd. (biennial wormwood, armoise bisannuelle) is an annual or biennial species native to western North America. Closely related species occur in Eurasia and South America which are sometimes considered conspecific. Spreading elsewhere in North America occurred along transportation corridors soon after European settlement and it has since been introduced to other parts of the world. As an economically important weed its impact appears to be increasing, possibly due in part to reduced tillage practices. The most significantly affected regions are the Prairie Provinces of Canada and the northern Great Plains in the United States. Many cereal, oilseed, pulse, vegetable and forage crops are affected where it can reduce yields at relatively low densities. A wide range of soil and moisture conditions are tolerated and it can form dense populations in disturbed habitats where its competitive ability is enhanced by prolific seed production, indeterminate seedling emergence and allelopathic effects. Although tolerant of a number of herbicides in different classes, good control can be achieved through careful timing and split application strategies.

Byker, H. P., Soltani, N., Robinson, D. E., Tardif, F. J., Lawton, M. B. and Sikkema, P. H. 2013. Control of glyphosate-resistant Canada fleabane [Conyza canadensis(L.) Cronq.] with preplant herbicide tankmixes in soybean [Glycine max. (L). Merr.]. Can. J. Plant Sci. 93: 659-667. Glyphosate previously provided excellent control of Canada fleabane; however, with the evolution of glyphosate-resistant (GR) Canada fleabane in Ontario, alternative herbicides must be identified for control of this weed in soybean. The objective of this study was to identify preplant herbicide tankmixes that provide effective control of GR Canada fleabane. A total of 12 field trials were completed over a 2-yr period (2011, 2012) in fields previously confirmed with GR Canada fleabane. Preplant tankmixes of glyphosate (900 g a.e. ha^-1) plus saflufenacil (25 g a.i. ha^-1) or saflufenacil/dimethenamid-p (245 g a.i. ha^-1) provided greater than 87% control 4 wk after application (WAA) across all sites. Glyphosate (900 g a.e. ha^-1) tankmixed with metribuzin (1120 g a.i. ha^-1), cloransulam-methyl (35 g a.i. ha^-1) or flumetsulam (70 g a.i. ha^-1) provided 78 to 99% control 8 WAA. Control of GR Canada fleabane prior to soybean emergence is essential as currently there are no herbicides that provide acceptable control in-crop. Because of the lack of in-crop options, spring residual herbicides may be required for season long control in regions where Canada fleabane emerges throughout the year to reduce Canada fleabane seed production and populations in subsequent years.

Soltani, N., Nurse, R. E. and Sikkema, P. H. 2013. Weed management in white beans with postemergence herbicide tankmixes. Can. J. Plant Sci. 93: 669-674. Weed control efficacy of cloransulam-methyl, halosulfuron, bentazon, fomesafen and their tankmixes applied post-emergence (POST) for weed management in white bean was evaluated in field studies conducted in four Ontario locations during 2008-2011. Cloransulam-methyl, halosulfuron, bentazon, fomesafen, bentazon plus fomesafen, cloransulam-methyl plus bentazon, cloransulam-methyl plus fomesafen, cloransulam-methyl plus bentazon plus fomesafen, halosulfuron plus bentazon, halosulfuron plus fomesafen, and halosulfuron plus bentazon plus fomesafen caused white bean injury ranging from 1 to 18%. Control for AMARE, AMBEL and CHEAL ranged from 47 to 92%, 66 to 98% and 36 to 91%, respectively, among herbicide treatments. Similar results were observed for weed density and biomass of AMARE, AMBEL, and CHEAL. Cloransulam-methyl, halosulfuron, and cloransulam-methyl plus fomesafen reduced the yield of white bean by 34, 21, and 17%, respectively, compared with the weed-free control. However, bentazon, fomesafen, bentazon plus fomesafen, cloransulam-methyl plus bentazon, cloransulam-methyl plus bentazon plus fomesafen, halosulfuron plus bentazon, halosulfuron plus fomesafen, and halosulfuron plus bentazon plus fomesafen had no adverse effect on yield of white bean. Based on these results, tankmixes of cloransulam-methyl and halosulfuron with bentazon and fomesafen can reduce crop injury and provide control of broadleaf weeds in white bean.

Ba, Q. S., Zhang, G. S., Wang, J. S., Che, H. X., Liu, H. Z., Niu, N., Ma, S. C. and Wang, J. W. 2013. Relationship between metabolism of reactive oxygen species and chemically induced male sterility in wheat (Triticum aestivum L.). Can. J. Plant Sci. 93: 675-681. Chemically induced male sterility (CIMS) systems in wheat are among the male sterility types used for hybrid wheat (Triticum aestivum L.) production in China. Some studies suggested that male sterile line Xi'nong 1376-CIMS induced by chemical hybridizing agents (CHA) may suffer from oxidative stress as its cyanide-resistant respiration is lower than that of Xi'nong1376. To elucidate the metabolic mechanism of reactive oxygen species (ROS) in the CIMS anthers, the metabolism changes in the production and scavenging of ROS and gene expression related to ROS-scavenging enzymes were investigated in the anther of Xi'nong 1376-CIMS and Xi'nong1376.Anthers of Xi'nong 1376-CIMS had higher contents of and H₂O₂ than those of 1376, which corresponds to expression level of the NADPH oxidase (NOX) gene, and has higher contents of malondialdehyde compared with 1376. Simultaneously, there were lower activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and ascrodate peroxidase (APX) in scavenging ROS in the anthers of the Xi'nong 1376-CIMS line than in Xi'nong1376. Meanwhile, the expressions of SOD, POD, CAT and APX genes in 1376 were always higher at different levels than those in the Xi'nong 1376-CIMS line except for POD in stage 1. Therefore, it is possible that the sterility in Xi'nong 1376-CIMS is related to the abortion of microspores induced by chronic oxidative stress caused by an abnormal increase in ROS.

DeLong, J. M., Hodges, D. M., Prange, R. K., Forney, C. F., Fan, L., Bishop, M. C., Elliot, M. L., Jordan, M. A. and Doucette, C. 2013. The influence of cold water storage on fatty acids, antioxidant content and activity, and microbial load in ostrich fern (Matteuccia struthiopteris) fiddleheads. Can. J. Plant Sci. 93: 683-697. The influence of upwards to 42 d of cold water storage (CWS) on selected bioactive compounds and microbial populations in ostrich fern (Matteuccia struthiopteris) fiddlehead tissue was investigated. Following harvest, the fiddleheads were stored in cold deionized water (1°C) with removals occurring at 1, 8, 18, 28 and 42 d. Post-removal analysis showed fiddlehead tissue had a unique fatty acid composition including γ-linolenic, dihomo-γ-linolenic, arachidonic and eicosapentaenoic acids. Post-storage tissue concentrations of ascorbic acid, a- and γ-tocopherol, a- and ß-carotene, the xanthophyll pigments (violaxanthin, zeaxanthin and lutein) and phenolic compounds ranged from high to very high for green plant tissue. High antioxidant activity values were also recorded and were likely due to the elevated phenolic compound content. Site differences were also apparent for several of these measurements. The microbial data showed that the fiddleheads had relatively high populations of bacteria as well as yeast and fungi resident on the tissue and in the surrounding storage water. Significant linear and quadratic CWS effects (both positive and negative) occurred for many of the bioactive compound and microbial measurements. A CWS period of a month or perhaps longer at 1°C appears possible for ostrich fern fiddleheads before the nutritional content markedly declines.

Badu-Apraku, B., Akinwale, R. O., Obeng-antwi, K., Haruna, A., Kanton, R., Usman, I., Ado, S. G., Coulibaly, N., Yallou, G. C. and Oyekunle, M. 2013. Assessing the representativeness and repeatability of testing sites for drought-tolerant maize in West Africa. Can. J. Plant Sci. 93: 699-714. The selection of suitable breeding and testing sites is crucial to the success of a maize (Zea mays L.) improvement programme. Twelve early-maturing maize cultivars were evaluated for 3 yr at 16 locations in West Africa to determine the representativeness, discriminating ability, and repeatability of the testing sites and to identify core testing sites. Genotype main effect plus genotype by environment interaction (GGE) biplot analysis revealed that Zaria (Nigeria), Nyankpala (Ghana), and Ejura (Ghana) displayed the highest discriminating ability. Two mega-environments were identified. Bagou, Nyankpala, Bagauda, Ikenne, and Mokwa constituted the first mega-environment (ME1); Ejura, Ina and Sotuba represented the second (ME2). The ME1 would be more useful for evaluating early maize genotypes for tolerance to drought than ME2 because locations in ME1 were more strongly correlated to Ikenne (managed drought stress site). Among the test locations, Bagou and Mokwa were found to be closely related to Ikenne in their ranking of the cultivars for drought tolerance; Zaria was the exact opposite, indicating that this was the least suitable location for evaluating genotypes for drought tolerance. Nyankpala and Ikenne were identified as the core testing sites for ME1 and Ejura for ME2. TZE Comp 3 C2F2 was identified as the highest yielding cultivar for ME1 and Syn DTE STR-Y for ME2, indicating that they could be used as check cultivars. Ikenne, Nyankpala, and Ejura had moderately high repeatability. They were closer to the average environment axis of each mega-environment and will be useful for culling unstable genotypes during multi-locational testing. Other sites were less representative and not repeatable and will not be useful for evaluating early maize cultivars for drought tolerance.

Liu, S. B., Chai, Q. and Huang, G. B. 2013. Relationships among soil respiration, soil temperature and dry matter accumulation for wheat-maize intercropping in an arid environment. Can. J. Plant Sci. 93: 715-724. Spring wheat (Triticum aestivum L.) intercropped with maize (Zea mays L.) offers an opportunity to boost grain production in short-season areas, but little is known about the sustainability of the intercropping system. This study, conducted at an arid irrigation site in 2009 and 2010, determined water consumption and soil respiration (Rs) characteristics and their relationships to soil temperature (Ts) and above-ground dry matter (DM) accumulation for wheat/maize (W/M) intercropping compared with sole wheat and sole maize. The W/M intercropping had a co-growth period of 70-80 d, allowing the two intercropped species to complete their life cycles. Maximum DM rate for the wheat in the W/M system was significantly greater than that for sole wheat (57 vs. 51 g d^-1), which occurred at around 72 to 77 d after sowing (DAS), whereas the maximum DM rate for the maize in the W/M system was between 31.6 and 44.9 g m^-2 d^-1, or 30 to 43% lower than that of sole maize. The ercroppedhe umulation of a thetime to reach maximum DM was 96 DAS in 2009 and 80 DAS in 2010 for sole maize, and the corresponding time for the intercropped maize was delayed by 6 to 10 d. Soil respiration and DM was a curvilinear relationship; with the increase in DM accumulation, Rs increased, reached a peak at the early flowering stage for wheat and at the silking stage for maize, and then declined. Soil respiration increased linearly with increases in soil temperature during the growth period for both sole and intercropping, suggesting that farming practices aimed at reducing soil temperature will be effective in reducing carbon emissions. Evapotranspiration during the co-growth period averaged 44.1 mm for sole wheat and 48.5 mm for the intercropped wheat and 57.0 mm for sole maize and 48.0 mm for the intercropped maize, but soil water status had little or no effect on Rs. Wheat/maize intercropping had greater grain yield with lower soil respiration over the corresponding sole plantings, and it can serve as a sustainable cropping system for arid irrigation areas.

Isaak, C. K., Petkau, J. C., O, K., Ominski, K., Rodriguez-Lecompte, J. C, and Siow, Y. L. 2013. Seasonal variations in phenolic compounds and antioxidant capacity ofCornus stoloniferaplant material: Applications in agriculture. Can. J. Plant Sci. 93: 725-734. The present study was carried out to establish the antioxidant capacity of plant material of Cornusstolonifera (syn. Cornus sericea, Red Osier Dogwood) grown in Manitoba, by measuring total phenolic content and oxygen radical absorbance capacity (ORAC) over a 3-yr period. The presence and concentrations of flavonoids that might account for antioxidant abilities were investigated using ultra-performance liquid chromatography and a total anthocyanins assay. Both ORAC levels and phenolic content increased during the spring, peaked during the summer months (1631.65±166.30 µmol trolox equivalents g^-1 DW in July 2011, 220.38±2.29 mg gallic acid equivalents g^-1 DW in August 2012), and then declined during the fall in all 3 yr. Analysis of individual flavonoids in 2010 samples revealed that high levels of rutin, a glycoside of quercetin, were present ranging from 7.46±0.09 (July 2010) to 18.77±0.23 mg g^-1 dried sample (October 2010). Anthocyanin content was high in the spring, very low in the summer months, and increased in the fall over all 3 yr. Although polyphenolic and antioxidant content in Cornus spp. plants have been largely attributed to their berries, results from this study demonstrate that other plant material may also be an abundant source of these compounds.

Plant Sci. 93: 735-739. In this preliminary study, Picea glauca seedlings were root drenched with a commercial liquid extract of Ascophyllum nodosum in finisher fertilizer (8N-20P-30K) at the following rates: 1:500, 1:250, 1:125, and 1:75. Fertilizer alone served as control. Applications were made four or eight times over a period of 17 or 43 days, respectively. Compared with control, all rates reduced total root system length in mid October by 44-54%. After freezer storage and then growing under favorable conditions in spring for 21 d, the 1:125 and 1:75 rates increased the number of white roots emerging from the intact peat plug by 42 and 63%, respectively.

Emerson hard red winter wheat (Triticum aestivum L.), a cultivar developed using doubled haploid technology, was registered for western Canadian production in 2012. It is eligible for grades of the Canada Western Red Winter (CWRW) wheat market class. Evaluation across western Canada from 2008 to 2010 was relative to CDC Osprey, AC Bellatrix, Radiant, and CDC Buteo, the CWRW wheat checks in the Western Winter Wheat Cooperative Registration trials. Overall, Emerson had significantly lower grain yield than the mean of these checks; however, in the stem rust, leaf rust and fusarium head blight prone eastern prairies the grain yield of Emerson was not significantly different from CDC Buteo and CDC Falcon, which have been the predominant cultivars in this region. Emerson had good winter survival, intermediate maturity, medium height, strong straw, high test weight, and high grain protein concentration. It expressed improved resistance to fusarium head blight, stem rust, leaf rust, and stripe rust relative to the checks. End-use suitability analysis indicated that Emerson had strong dough rheology, and excellent milling and baking properties.

Mitchell Fetch, J. W., Tekauz, A., Brown, P. D., Ames, N., Chong, J., Fetch, Jr., T. G., Haber, S. M., Menzies, J. G.,, T. F. Townley-Smith, Stadnyk, K. D. and Green, D. A. 2013. Stride oat. Can. J. Plant Sci. 93: 749-753. Stride is a white-hulled spring oat (Avena sativa L.) cultivar with moderate resistance to fusarium head blight. It is postulated to carry the crown rust resistance combination Pc39,Pc68 and Pc94, which was effective against the prevalent crown rust races on the Canadian prairies at the time of its release. It has very good resistance to loose and covered smut, moderately good resistance to most of the prairie stem rust races (likely due to the presence of Pg2 and Pg13), and intermediate reaction to barley yellow dwarf virus (BYDV). Stride has high test weight, but low kernel weight. Stride exhibits high yielding capacity in the oat growing areas of western Canada. Stride was registered (Reg. No. 7180) in Canada 2012 Apr. 23.
