GRAIN QUALITY OF SPRING SOFT WHEAT VARIETIES IN THE CONDITIONS OF THE SUBTAIGA ZONE OF THE TYUMEN REGION
The aim of the study is to assess the content and quality of gluten in the grain of spring soft wheat varieties of different maturity groups grown in the subtaiga zone of the Tyumen Region. Field experiments on the study of spring wheat varieties were carried out at the Nizhnetavdinsk state variety section of the Tyumen region, conducted by the state testing service in accordance with the methodology adopted in variety testing. The soil of the experimental plot is gray forest. The predecessor is pure steam. Determination of the content and quality of gluten in the grain of midearly and midseason wheat varieties of the harvest of 2017 and 2018 was carried out in accordance with GOST R 544782011 «Methods for determining the amount and quality of gluten in wheat». In 2017, 35 varieties were studied, in 2018 - 25 varieties. As a result of the study, signifi differences between midearly and midseason varieties in terms of the gluten content in the grain and insignifi differences in the quality of gluten were found. Most of the midearly varieties in both years of research on the gluten content in grain were within the requirements of the fi class of GOST. Under the conditions of 2017, the grain of the majority of midseason varieties corresponded to the standards of the third class in terms of the gluten content, and in the conditions of 2018 - to the standards of the fi class. The varieties Novosibirskaya 31, Novosibirskaya 15, and Iren were characterized by a high gluten content in both years of the study (more than 35 %). The quality of gluten in most of the studied varieties corresponded to the second group with indicators of 78-90 units of IDK. In terms of the content and quality of gluten in grain, the high requirements of the fi class of GOST were met: in 2017, the midearly variety Yarovita and the midseason Novosibirskaya 61; in 2018 - medium early varieties Novosibirskaya 31, Novosibirskaya 15, Ishimskaya 11 and midseason Atlanta 1, Stolypinskaya 2, Nerda. The results obtained can be used by agricultural enterprises in the region in terms of selecting varieties for the production of highquality food grain of wheat.
