YIELD AND QUALITY OF GRAIN OF "TVERDYNYA" SPRING HARD WHEAT CULTIVATED UNDER THE CONDITIONS OF ORENBURG PREDURALYE
The grain yields and quality indices of the new “Tverdynya” variety of spring hard wheat cultivated in the Orenburg Preduralye are described in the article. The new variety has demonstrated its superiority in grain yields as compared with the yields of standard Orenburgskaya-10 and Bezenchugskaya steppe wheat varieties in competitive, production and state tests. The analysis of grain quality obtained in different zones of the Orenburg region shows that the “Tverdynya” variety forms grain of high quality in the main cultivation zones. By the mass of 1000 grains and grain nature, the new wheat variety surpasses the standard Bezenchuk-steppe one in the northern and central zone, while in the eastern zone it is somewhat inferior to the above variety. There were observed higher indices in grain glassiness, raw gluten and protein content than those of standard varieties in all the zones of the Orenburg region under study. The introduction of the new wheat variety under the conditions of the Orenburg region is to expand the raw material base of the pasta industry under the conditions of hard wheat grain scarcity and it is to contribute to satisfaction of the consumer demand for high-quality pasta products.
