Abstract
The article presents the results of studies of 6 new varieties and genotypes of spring hard wheat, created in the research center of the FGBNU "DZNIISH", adapted to the conditions of the climate continentality increase in the Rostov region. The data of three-year studies are presented, in which the main attention is paid to indicators of yield, resistance to disease and lodging. Promising genotypes of mutant origin showed high resistance to powdery mildew (1-10%) and yellow rust (5-15%), ripened at the standard level or 1-2 days later. When examining varieties of hybrid origin, increased drought resistance was noted. The significance of the influence of climatic conditions on the yield and quality of grain is shown. It was noted that in conditions of drought the quality of grain increased. The number increase in protein was observed in 2014 (up to 16,3% in GOST 4985/13) and gluten in grain (up to 34,5% in Gord., 5057/12). With sufficient moisture in 2016, the amount of gluten was the lowest (24,7-31,0%), and the nature and mass of 1000 grains were the highest: 810 g / l and 41,2 g (in Donela M cultivar). All of the above lines were characterized by high resistance to lodging (except for cultivar 5057/12) despite the fact that in 2016 they were tall. During the years of study in competitive strain tests, new varieties of samples consistently yielded high yields: from 2,67 t / ha to 3.80 t / ha. It is shown that promising genotypes have high ecological plast
icity. When studying in ecological variety testing in Krasnodar NIISH, the yields were surpassed by the standard Volnodonskaya, and the variety of Nicolasha: Gord. 5036/12 – 5,34 t / ha, Gord 4970/13 − 4,56 t / ha.
