| Title : | ASSESSMENT OF POSITIVE CHANGES IN WINTER WHEAT VARIETIES UNDER MUTAGEN TREATMENT |
| Abstract : | The exploration of novel agents capable of inducing practical genetic diversity in modern winter wheat varieties represents a significant avenue for enhancing both commercial wheat breeding and recombination-based selection methods. This study investigated the effectiveness of a relatively novel chemical mutagen, 1,4-bisdiazoacetylbutane (DAB), as an inducer of beneficial variability in grain yield and quality attributes, as well as in other agriculturally significant traits. Eight varieties of winter wheat (Perspektyva Odeska, Sonata Poltavska, Shpalivka, MIP Lada, Farell, NE 12443, Ronin, and Seilor) were exposed to the mutagen DAB at three concentrations: 0.1%, 0.2%, and 0.3%. Among the tested varieties, Farell, Ronin and Seilor exhibited the highest responsiveness, making them particularly favorable candidates for targeted mutagenesis aimed at enhancing beneficial traits. Optimal results, characterized by substantial genetic variability and an increased proportion of agriculturally beneficial forms, were consistently achieved at the highest DAB concentration tested (0.3%). Two particularly promising mutant lines emerged from the study, exhibiting the most favorable combination of high grain productivity, consistent yield stability and desirable grain quality traits suitable for bread-making purposes. Furthermore, several other mutant lines derived in this study exhibit significant potential as valuable parental lines for cross-breeding. |
