Abstract: The article presents information about the yield, nutritional value of the green mass of clover, the collection of dry matter, the yield of seeds in the nurseries of competitive variety testing of different years. Ksinursery was founded in 2015 and 2016, were evaluated biaxial numbers and hybrid populations of clover. The area of the plot is 10 m2, the repetition is fourfold, each nursery has 14 rooms. Weather conditions in 2015‒2017 were markedly different from the annual average. SCC for the growing season in 2015 amounted to 2.13; in 2017 ‒ 1.54, which is close to the mean annual values (1.57), and in 2016 – 0.81, which is characterized as favorable. The yield of green mass in clover numbers of the first year of use in 2016 was in the range of 5.3‒7.8 t/ha in the first mowing and 14.8 ‒ 21.3 t/ha in the second. In total, for two mowing, the yield of green mass in the rooms was 38.5‒41.8 t / ha and the collection of dry matter for the season ‒ 3.35‒4.46 t/ha. Clover of the third year of life (2017) formed in the first mowing the yield of green mass 17.0‒23.3 t/ha, and in the second mowing the yield was lower and amounted to 5.5‒9.5 t/ha. In the two mowing green mass yield was from 23.5 to 32.1 t/ha of dry matter ‒ 3,53 ‒ of 5.31 t/ha. According to the results of the assessment in the nursery of competitive variety trials planting 2015 of greatest interest for complex traits represent numbers: 172‒10, 171‒10, 173‒10, 168‒10, Dixon. The selected promising hybrids will be further breeding and study.
