Investigation method; Multi-step hybridization with the usage of donors of economically valuable traits and subsequent individual-family selection as regards to combining ability. Brecding is being conducted only on short-stem basis. For the dwelopment of such cultivars we use short-stem donors with dominant monogenic and recessive polygenic governing of a trait. The transfer of short stem and other valuable traits is carried out by means of bachcrosses with futher homoxygotiration. Theoretical and practical results: a new winter rye cultivar Khasto was created and registered at the State Variety Trials in 1999. There have been widened the experiments to study sterility heritability, self-fertility, to create self -pollinated lines, ЦЧС, systems and winter rye hybrids on the basis. In 2000 the first winter rye hybrid in CIC countries was registered in the State Variety Trials, called Pervistok. Product Description popup.authors popup.nrat_date 2020-04-02 Close
