Abstract
Objective. To investigate the influence of mutagenic factors on the length of the stem in the varieties and hybrids M1, F2M1 and hybrid populations of F3M2 -F5M4wheat of soft winter. Methods. Laboratory for structural analysis of plants, statistical - to determine the variability and reliability of the results. Results A greater number of short-stemmed plants was detected compared to control in variants treated with mutagenic NMCs 0.05%, NES 0.05; 0.1% in M1, F2M1. By mutagenic treatment in the hybrid combinations of F3M2-F5M4 the distribution pattern, mean values and coefficients of variation over the stem length change. Intermediate succession produced less fertile plants. Conclusions The extension of the range of variability based on the length of the stem in the varieties and hybrids M1, F2M1 and the hybrid-mutant populations of F3M2-F5M4 soft winter wheat. Highlighted hybrid mutant populations.

Key words: winter wheat, hybrid combination, length of stem, generation, mutagen, concentration.
