High protein mutants of winter fodder barley induced by radiation and chemical mutagens



High protein mutants of winter fodder barley induced by radiation and chemical mutagens



Genetika i Selektsiya 15(4): 265-269



Several induced mutants of winter fodder barley with high protein content are described. These mutants were produced by treating seeds of cvs. 'Vogelsanger Gold', 'Ager' and '468' with .gamma.-rays, sodium azide and ethyl methanesulfonate (alone and in combinations) and with ethyleneimine and formamide. The .gamma.-ray induced mutants of winter fodder barley had 1-4% higher protein content. The mutant line 109 had, besides high protein content (17.37%), 5.96 lysine/100 g protein, but its endosperm was wrinkled. Mutants produced by chemical mutagens had 6-7% higher protein content than the initial cultivars. All induced mutants had 85-95 cm high stems, i.e., they were 10-20 cm shorter than the initial cultivars. Some of these mutants were more resistant to Helminthosporium gramineum and Ustilago nuda.
