Investigation of the usability of the ''Corn grass'' mutant type in breeding

Some crossings between the normal inbred line B-14, and two types from ''corn grass'' macromutant, were carried out. The two hybrids ''A'' and ''B'' were compared with two Hungarian standard varieties, MvSC-580 and Mv-26/430. The results showed significant differences between the two hybrids and the two standard varieties in plant height, in the number of ears, in the number of tillers, in the number of leaves, and in the leaf area index characters. There were significant differences in the yield and yield components as well as in the protein content and in the mineral composition. (author)
