Abstract
The analysis of long-term data showed that in various agrometeorological conditions, the average yield of the selected numbers of the competitive test was 6.76 t/ha and varied from 6.15 t/ha for the line 4/3-12h 933 to 7.04 t/ha for the Noble variety. The maximum yield was shown in 2016 in the varieties Znatny, Nadezhny and breeding lines 30/3-12h 983 and 135/2-12h 1068 at the level of 8.91 to 9.52 t/ha. The differences between the samples in terms of the level of crop structure elements were revealed. In the group of high-yielding genotypes, breeding lines 141/1-09 h 746, 135/2-13 h 1068, 4/3-12 h 933 were distinguished, the weight of 1000 grains in which was 1.7-5.6 g higher than the average value. Ranking by the complex of the most important productivity characteristics determined the high breeding value of Yaromir, Nadyozhny, Znatny varieties and lines 30/3-12h 983, 135/2-13h 1068 as a source material for breeding to increase the yield of new varieties.
