PRODUCTIVITY AND QUALITY OF WINTER WHEAT VARIETY GRAIN IN CONDITIONSOF MIDDLE VOLGA REGION STEPPE
The purpose of research is to increase the productivity and quality of winter wheat variety trials competitive grain varieties, depending on weather conditions. Studied varieties: Povolzhskaya 86, Kinel’skaya 8, Povolzhskaya niva, Konstantinovskaya. Varieties cultivated by traditional technology, the fresh pair. The data for the 2012-2015 biennium. Grain quality was assessed a number of indicators that characterize its physico-chemical and technological properties: nature grain, vitreous, the strength of flour, protein content, adhesive wine. The maximum value in terms of nature is characterized by grain corn all classes in 2013 and 2014 (782-816 g/l). The high rate of vitreous grains observed in 2012, 2014, 2015 (72-92%). Good data on the same data obtained for the protein content, wet gluten flour strength. It was found that the environmental conditions during the formation and ripening of grain in years of research have a significant impact on productivity and ka-honors winter wheat. The study group of varieties set up in the laboratory breeding and seed, has a rapid rate of accumulation of dry matter. They are adapted to the formation of us, full grain in the conditions of unstable arid climate of the Middle Volga region.
