In addition to increasing grain yield, a promising direction in the use of mutagens is to obtain complex changes that increase the content and quality of grain protein. The main purpose of investigation is to develop possibilities of difference mutagen agents in induction mutants by protein content and quality, bread-making technological qualities and pathways for obtaining forms with combination of good grain production and qualities parameters. From 13 perspective high grain productive mutant lines 3 were separated out by combination of good grain quality and grain productivity on the level no less than national standard. Medium dose of gamma-rays (100 Gy) and concentrations of nitrosomethilureas (0.0125%) are effectively for mutation breeding on grain productivity and quality in complex. It is planned to conduct research for the optimal doses and concentrations of mutagens to obtain forms which are tolerant to abiotic stresses.
