The purpose of our study was to show the possibilities of a chemical supermutagen in the regular induction
of certain types of mutations. Winter wheat dry seeds of eight varieties were acted with water (control) and
DAB (1.4-bisdiazoacetylbutane) action in concentrations of 0.1%, 0.1%, 0.3%. Studies have shown that the
use of this mutagen is expedient from the point of view of obtaining valuable forms of low-growing, earlyripening,
late-ripening, high-yielding lines, forms with high productive tillering. The mutagen by its nature
has a rather low affinity, at least for this group of genotypes, however, this factor still affects the frequency
of some types of mutations. Even extreme concentrations of this mutagenic agent did not lead to a significant
decrease in the number of mutations; however, they reached a maximum in the spectrum of possible
changes. Further studies are needed on changes in photosynthetic activity and associated persistence.
