NEW VARIETIES OF SPRING SOFT WHEAT

In terms of differentiation of agricultural enterprises by the level of intensification of grain production it is necessary to cultivate varieties that are most adapted and cost-effective for specific levels of technologies of growing spring wheat. This is confirmed by the ecological variety testing, which was carried out in different soil - climatic and technological conditions. In the Vladimir niiskh on gray forest soils under normal technology, the new variety of mA’am was characterized by the highest yield, resistance to lodging and disease. In the competitive variety testing on average for 10 years, he provided a yield of 37.7 C / ha (higher than the best studied in the experience of varieties by 5.9-10.3 C/ha) with resistance to lodging 8.4 points on a 9-point scale. The maximum yield varieties in 2009 was 62.0 q/ha. During the last 5 years of competitive variety trials the most stable and productive years was a kind of heater, which on average for 2013-2017 exceeded the grade’am 4.6 t/ha in the same agricultural background. Among studied varieties of spring wheat the highest yields provided a variety Rook, cultivated on intensive technology: high soil fertility in the Republic of Belarus yields reached 99,0 kg/ha in 2013, and in Yaroslavl, NIIZK - 80,0 kg/ha in 2017 In the Vladimir research Institute of agriculture at high doses of fertilizer, but without the protection of plants from diseases, pests and lodging in 2017 received a yield grade of 73.0 kg/ha.
