| Title : | PECULIARITIES OF THE NEW EPIMUTAGEN ACTION ON VARIABILITY OF WINTER WHEAT |
| Abstract : | The study of new agents for enhancing biodiversity in local varieties of winter wheat is a promising approach for developing both new commercial varieties and components for recombination selection. The objective of this study was to explore the potential of Triton-305X (TX-305) as a epimutagen, focusing on optimizing the yield of epimutant forms derived from local varietal resources. Winter wheat seeds from four varieties were treated with water (control) and TX-305 at concentrations of 0.01%, 0.05%, 0.1%, and 0.5%. The most successful results for all varieties were achieved with TX-305 concentrations of 0.1% and 0.5%. Lower concentrations of TX-305 were not optimal for producing valuable forms. All varieties exhibited significant genotype-mutagenic interactions, leading to notable positive changes in variability parameters. This agent shows promise for generating short-stemmed, early-ripening forms, long-spiked lines, and high-yielding forms. The findings highlight the potential of epimutagens as a valuable tool in winter wheat breeding. By regulating chromatin modifications, epimutagens provide a controlled approach to inducing variability, offering new possibilities for crop improvement in response to changing environmental conditions. Further research will focus on the long-term stability of epimutagen-induced traits and their integration into commercial breeding programs. |
