The genetic factors that condition resistance to kernel discoloration caused by Bipolaris sorokiniana in barley (Hordeum vulgare) were transferred from Chevron (CI 1111) and CI 9539 into lines and cultivars that were somewhat adapted to Minnesota and were then incorporated into potential cultivars by crossing to Manker and Morex. Selection for kernel discoloration was effective in the F₂ through F₄ generations in two populations, and kernel discoloration was sufficiently heritable in three other populations to justify selection in the F₂ and F₃ generations.
