The study of the ability to androgenesis in the winter soft wheat anthers

Abstract

The improvement of genetic diversity and acceleration of breeding process are the most important tasks in wheat breeding. In vitro biotechnological methods are of practical interest for breeding process. The current paper has considered the effects of genotypes and nutritious medium on the formation of regenerants. The purpose of the research was to study the ability to androgenesis in winter soft wheat anthers and to identify promising winter soft wheat genotypes. The estimation of the ability to androgenesis was carried out among ten winter wheat samples. 8711 anthers were planted on medium of N6 and PII induction; the 190-2 medium was used for regeneration. As a result of the study, it was found that the process of neoplasms occurrence depends both on the variant of the nutrient medium and on the chosen genotype. It has been proven that the most favorable medium for the cultivation of winter soft wheat anthers is medium N6. It was found that the maximum percentage of neoplasms (5.21%) from winter soft wheat anthers was recorded in the sample “595/13”. It was found that the samples “595/13” (9 plants) and “Niva Dona” (6 plants) developed by the FSBSI “Agricultural Research Center “Donskoy” showed the highest responsiveness to the formation of calluses and plants-regenerants. There were obtained 6 green regenerants and 3 albino forms from the pollen callus of the sample “595/13” and 4 green regenerants and 2 albino regenerants from the sample “Niva Dona”.
