Duguid, S. D., Rashid, K. Y. and Kenaschuk, E. O. 2014. Shape flax. Can. J. Plant Sci. 94: 157-160. Shape, a medium maturing oilseed flax (Linum usitatissimum L.), was released in 2007 by Agriculture and Agri-Food Canada, Morden Research Station, Morden, Manitoba. Developed from the cross M4684/FP1043 made in 1997, Shape was evaluated in the Flax Cooperative Trials in (2004-2006) before being registered in 2007. Shape's desirable combination of agronomic traits and seed quality, particularly its significantly improved oil and protein content, oil quality profile and disease resistance, should make it a useful and unique cultivar for producers and the flax industry.
