摘要

The aim of this study was to acquire winter wheat lines with good quality, containnig untraditional HMW-GS (17+18, 13+16), for future incorporation to breeding processes for the purpose of developing new varieties with improved bread-making quality. At first, two sets of progeny were obtained by crossing. In the first set the influence of HMW-GS on breadmaking quality indicators was evaluated in F3 and F4 generations. In F3 generation SDT value was influenced significantly (P<0.01) by alleles at Glu-1A and Glu-1D loci, in the F4 generation SDS test value was significant influenced by alleles of all three loci - Glu-1A, Glu- 1B (P<0.01), Glu-1D (P<0.05), respectivelly. Protein content in the F3 generation was significantly influenced (P<0.01) by alleles on Glu-1A loci, while in the F4 generation on Glu- 1B loci. Hardness of corn was significantly influenced (P<0.01) by alleles at Glu-1D loci in both generations. Wet gluten content was statistically influenced (P<0.01) by alleles on Glu- 1D loci. Quality of second set was not statistically evaluated in the F3 generation.
