| Summary: | In Ukrainian forest-steppe environments, breeding for winter hardiness is one of the main directions in the development of winter wheat varieties. Crosses, selection of winter forms from spring wheat varieties sown in autumn, and intravarietal selection are the basic methods of development of winter-hardy forms. Availability of stress factors may help selection of transgressive winter-hardy morphotypes among F2 populations and variety genotypes. Further examination of selected forms allows choice of candidates according to the complex of adaptive traits. In different years, a number of lines were committed for state trial in Ukraine as varieties Oberih myronivs’kyi, Svitanok myronivs’kyi, and Myronivs’ka zolotoverkha and in Russia: Mironovskaya 100, Demiro 100, Mironovskaya kolosistaya, and Mironovskaya vasil’kovaya. Variety Mironovskaya 100 was included into the State register of breeding achievements of Russia in 2011. |
