The seeding rate is an important element of the technology of primary seed farming varieties of spring soft wheat

The paper reflects some aspects of the search and effective solutions to the problem of stable productivity increase of spring soft wheat in varietal technologies of original (primary) and elite seed production. For the study years (2015-2017) the analysis of the effect of different seeding rate on yield and the main economic and valuable traits of contemporary varieties of spring soft wheat breeding of the FPBSI Volga RISS. The criteria for selecting and correcting of optimal seeding rates for more complete realization of the biological potential of modern varieties and genotypes of spring soft wheat breeding of our Institute are defined. According to the research results for agricultural producers of the middle Volga region are given recommendations of optimal seeding rates for zoned varieties of spring soft wheat. For the varieties Kinelskaya 2010 and Kinelskaya yubileynaya - 4,5 million, for the variety Kinelskaya niva - 5,0 million, for the variety Kinelskaya otrada - 5,5 million viable seeds per hectare. Data for improvement of elements of technologies of primary seed farming of modern grades are received.
