The seed farming of the winter rye varieties of Saratov region

The seed farming questions of the winter rye population varieties on exemplum of Sararovskaya 7 are presented in the article. Individual selection of the plants from the family on the components was conducted in the nursery with growing space 10½40 cm2. The regular control on the results of all variety signs (winter hardiness, grain yields, number of the plants and stems on 1 m2, height of the plants, productive tillering, plant and head productivity) is conducted in competitive strain tests. For sowing are used the seeds from the nursery of the primary multiplication. The comparison of the once-growth original seeds varieties (PR-1 reproduction) (OC) on the grain yields in suitable climatic conditions shows the result of breeding work and quantitative possibility of the seed production in Saratov region. The results of the estimation of the winter rye varieties seeds sowing quality growing on the ARISER fields and Saratov region are shown. The uses of the primary selection in the seed farming schemes allow both keeping the varieties and improve them. It raises the competition ability of the variety on the seeds market. It was grounded that seed farming of the winter rye population varieties is profitable in connection with possibility to obtaining of the next seed reproductions with smaller expenditures in the agricultural economy of the different property forms with participation of the author or originator at seed production of higher reproductions for realization. It was grounded that seed farming of the winter rye to allow provide the grain farming agriculture with accessible and qualitative seeds.
