Abstract

The technological parameters of lines belonging to different grain hardness groups were studied in various generations. Studies on the wet gluten content, Zeleny index and farinograph water absorption indicated that the grain yields of F3 lines differed from each other in all the grain hardness groups, and as the hardness increased there was generally an improvement in the technological parameters. Compared with the results achieved for the F 3 lines, there was a reduction in the deviation between the quality parameters of lines in the F5 generation, which can be primarily attributed to selection. For this reason the minimum values were also higher in general than in the F3. At the same time, it proved possible to select with greater frequency for lines with high Zeleny indexes and farinograph water absorption, in which hard grains were combined with good technological quality. It can thus be said that indirect selection for technological parameters on the basis of grain hardness may be successful especially in the case of farinograph water absorption and Zeleny index, but the moderately strong correlations suggest that wheat genotypes with excellent technological properties could also be selected from grain hardness groups 50 and 60.
