        Inheritance of Straw Stiffness in Winter Barley (Hordeum vulgare L.)

        B.H. HOKG(洪丙憙),C.H. CHO(曺章煥),E.S. LEE(李殷燮),B.K. KIM(金鳳九) 한국육종학회 1980 한국육종학회지 Vol.12 No.2

        To clarify the genetics of straw stiffness and to establish a selection criterion for improvement of lodging resistance 8×8 diallel set and selected F₂ populations were grown at Suweon. The results obtained were summarized as the followings; 1. The components of variation estimated for straw stiffness suggested that the additive genetic variation is very important followed by dominant genetic variation. 2. The allelic distribution was unequal in the parents used and involvement of more dominant genes behaving additively was noticed. 3. Wr, Vr analysis indicated that Kangbori is recessive gene carrier compare to others. Buhung seemingly carries non-allelic dominant gene against to other varieties. 4. F₂ analysis suggested that Kangbori carries two recessive genes associated with stiff straw. Buheung and Olbori may carry one dominant gene which is non-allelic each other. 5. Among the parents tested Buheung. Kangbori Suweon 4, Olbori and Samheung were good combiners while Suweon 18, Suke 165 and CI 6332 were the poors. 6. Heritabilities estimated were high enough to be effective in selection for culm stiffness in the early segregating population.
