Screening of Promising Selection Samples of Alfalfa Variable in Productivity and Longevity

The article presents the results of studying the numbers of alfalfa variable in breeding nursery (2011- 2019 and 2015-2019) on the complex of economically valuable traits. High winter resistance of all varieties was revealed. On average, for three years in the breeding nursery the establishment of 2015-2019 years significantly exceeded the standard number on the seed yield: Victoria — by 70%, CHP-1 — 84%, CHP-2 — 24%, 192-92 (f) — 41%, 213 -11 — 74%. For three years of testing all these promising numbers significantly exceeded the Sarga variety (standard) in seeds yield. On average for three years the yield of green mass was 5.0-20.1 kg/10 m2 . According to this indicator the following samples significantly exceed the standard: Victoria — by 20.4%, 213-11 -5.1%, 199-06 — 15.0%. Dry matter collection was 1.08-4.27 kg/10 m2 (standard 3.78 kg/10 m2 ), excess of 4.5- 13.0%. During the longevity test in the breeding nursery of alfalfa (sowed in 2011) the following data was obtained: the seeds yield of breeding numbers in 2019 was 50.0 - 333.3 g from 10 m2 . The highest yield was noted in numbers: 20-89N (st), 203-06, 197-06/1, 27-86 (f), 199-06/1, 101-2 (st), 20-89N (st).
