Effect of gamma irradiation of seeds on the development of Phaseolus vulgaris L. plants

Relevance. The modern direction of bean breeding is focused on increasing the protein content in seeds and green beans, as well as vitamins, folic acid, biologically active substances and antioxidants, improving organoleptic properties and reducing the content of anti-nutritional substances. When creating the initial material for breeding, the following traits are important: resistance to biotic and abiotic factors, stable high yield, technological effectiveness, bush type and upright form, high symbiotic activity. An effective approach to increasing the genetic diversity of the initial material is radiation mutagenesis. Purpose of research. To study the effect of γ-irradiation of seeds on germination, morphometric parameters and duration of phenophases of Russian bean varieties and to determine the optimal dose of γ-radiation for the radiation mutagenesis protocol.
