The article presents the results of a study of the adaptive ability of winter soft wheat varieties in terms of yield and grain quality in the conditions of the forest steppe of the Middle Volga. Studies were conducted in 2013–2015 at the Penza Research Institute of Agriculture. The research material was 17 varieties of winter soft wheat, including 9 zoned varieties and 8 varieties of own breeding. Vegetation conditions during the years of research varied in temperature and the amount of precipitation. The vegetation period of 2013 was characterized by favorable conditions, 163.9 mm of precipitation fell over the entire period, which is 6.7 mm higher than the average long-term norm, the average daily air temperature is 17.1 ?С (higher than the average annual norm by 2 ?С), hydrothermal coefficient (GTK ) is 1.1. In 2014 and 2015 drought during the was observed exit to the earing tube — water supply was 13.4 mm and 20.8 mm, which is 27.5 mm and 20.1 mm lower than the average long-term norm; increased average daily air temperatures up to 18.8 ?С and 17.6 ?С, which is higher than the average annual norm by 3.4 ?С and 2.0 ?С; GTK 0.2 and 0.4, respectively. As a result of studying varieties of winter soft wheat under different growing conditions using stability parameters, the most suitable varieties for cultivation in the forest steppe of the Middle Volga region were identified and recommended as starting material: the grain productivity, Lutescens 35 / 01-2-07 (S2di = 3.6), Lutescens 26 / 03-1-06 (S2di = 10.4); according to the total glassiness, Moskovskaya 39 (bi = 0.37, S2di = 0.19), Lutescens 26 / 03-1-06 (bi = 0.73, S2di = 0.17), Bezenchukskaya 380 (bi = 0.81, S2di = 0.66), Biryuza (bi = 0.81, S2di = 0.86); the nature of grain Biryuza (bi = 0.12, S2di = 2.2), Klavdiya 2 (bi = 0.25, S2di = 8.1), Nympha (bi = 0.75, S2di = 6.3); according to the quality of gluten in grain Bezenchukskaya 380 (bi = 0.63, S2di = 0.60), Lutescens 26 / 03-1-06 (bi = 0.94, S2di = 0.11); according to the protein content in the grain, Bezenchukskaya 380 (bi = 0.88, S2di = 0.25), Orenburgskaya 105 (bi = 0.86, S2di = 0.01), Moskovskaya 39 (bi = 0.90, S2di = 0, 01), Alonushka (bi = 0.94, S2di = 0.26), Lutescens 35 / 01-2-07 (bi = 0.93, S2di = 0.09); according to a set of attributes Bezenchukskaya 380, Lutescens 35 / 01-2-07, Lutescens 26 / 03-1-06 for creating new forms.
