Abstract

Twelve perennial small grain cultivars were examined for eight characteristics favorable to management of greenbug, Schizaphis graminum (Rondani). A greenbug-susceptible variety of hard red winter wheat, Triticum aestivum L., and a greenbug-resistant hard red winter wheat variety were used as checks. Eight of the 12 perennial small grain cultivars (including X Triticosecale spp. / Thinopyrum intermedium // X Triticosecale spp., X Triticosecale spp. / Thinopyrum ponticum // X Triticosecale spp., Thinopyrum ponticum / Triticum aestivum var. Eltan, X Agrotriticum spp. (PI550715) / Tripsacum dactyloides var. Spitzer, and Hordeum vulgare var. MT2 / Tripsacum dactyloides var. Spitzer) had at least one favorable greenbug management characteristic. Cultivars that included X Triticosecale spp. and either Thinopyrum intermedium (Host) Barkworth & D.R. Dewey or T. ponticum wheatgrass in their genetic background had the most favorable characteristics.
