【 摘 要 】

In Prevolzhsky Federal District winter rye is widespread food crop. The most important reserve of increase and stability of winter rye productivity is a use of new more productive stress tolerant cultivars, which possess better traits and make its growing profitable. Winter rye varieties which consist of great number of heterozygous components, show more stability in productivity and adapt to changing environment better. The article presented a method of breeding of adaptive and highly productive winter rye varieties, based on a combination of inter variety hybridization, assessment of the families on total combinative ability, continuous individual-family or recurrent selection by the method of halves. The use of poly crossing of specially chosen forms gave us an opportunity to increase a share of balanced genotypes with a maximum blend of economic-valuable traits in the population. The economic-biological features of the new winter rye variety ‘Tantan’ were given. The origin of the population is characterized by a wide genetic background, which allowed accumulating many useful traits. The variety is suitable for bakery. ‘Tantan’ combines high productivity, adaptability, good quality of grain and some other advantageous traits and it’s recommended for growing in three regions of RF.
