EVALUATION OF SPRING BARLEY GRAIN DIRECTION WITH IMPROVED PRODUCTIVITY FOR THE PURPOSES OF THE PROCESSING INDUSTRY IN THE СENTRAL NON-BLACK EARTH ZONE
A study on the identification of promising varieties and lines of barley for target grain breeding for the groats industry, an assessment of their technological properties and consumer advantages in comparison to already zoned varieties is a very topical area. For the purposes of the processing industry, the technological properties of barley grain of promising varieties and selection varieties of competitive variety trials were investigated, consumer properties of barley cereals obtained from the original grain and the grain subjected to hydrothermal treatment were studied. In the course of the research, it was established that the varieties Vladimir, Nadezhnyj and new varieties under State testing - Zlatoyar, Sudar 'and Znatnyj, had the highest nature of grain, which was 711-720 g/l. The largest weight of 1000 grains (50,5-51,2 g) had varieties Vladimir, Nur and Zlatoyar. The indicator «groats outcome in 4 minutes», corresponding to 56,6 and 57,6% with a glassiness of 33,2-41,8%, characterized the high potential of brewing grain Nadezhnyj, Sudar ', Znatnyj and a selection variety 141 / 1-09h 746 for use for pearl barley. Light cream color of porridge of the cooked groats, corresponding to 5 points, in the years of research had varieties Yaromir, Nur, Moskovskij 86, Zlatoyar and Znatnyj. The highest indicators of glassiness (42,8-45,2%) were found in the most large-grained varieties Nur and Zlatoyar. Along with valuable technological properties, the varieties and breeding lines selected during the research have good productivity. Under the conditions of the Ryazan region, the varieties Nadezhnyj and Yaromir showed the highest yield of 7,83-7,89 t/ha. At the same time, the indicator of the level of stability of the variety of all numbers of competitive tests was below the standard (Puss=43,2-95,9). The highest selection value relative to the standard had varieties Nadezhnyj, Sudar', (Puss=89,0-94,1), Zlatoyar, Znatnyj and breeding samples 35/1-09 h 662 and 141/1-09 h (Puss=82,0-95,9)<sub>.</sub>
