Abstract

 

Through the use of mutagens the diversity of the source material for breeding of winter wheat has been significantly increased. Perspective sources by the parameters of short steam, earliness, changes in shape and colour of the ear, productivity, protein content have been obtained. The frequency of mutations by these parameters has been developed, mutagenic factors and their optimal dose for the induction of this type of mutation have been defined. Earliness, ultra earliness, semi-dwarf, with long ears mutant lines have been developed as valuable. Six mutant lines with good productivity and protein content have been proposed for immediate use to breeding process. Мutant lines have been analysed by gliadins and gliadins formula of six promising lines has been showed.
