Abstract

Alfalfa variegated stands out for its high fodder qualities - nutritional value and digestibility, as well as improves soil fertility and structure, is an excellent predecessor for many crops. The purpose of the research is to evaluate of Alfalfa variegated varieties of the Omsk Agrarian Scientific Center selection in the conditions of the southern forest-steppe of the Omsk region and to identify the most promising material for further use in breeding and seed production. The object of research is the varieties Omskaya 7, Flora 7, Flora 8, Pamyati Goncharova. The studies were carried out in 2018–2021 on the experimental fields of the Omsk Agrarian Scientific Center. The most favorable weather conditions for the formation of increased yields of green mass, dry matter and seeds for all varieties developed in 2020. On average, over two cycles of research in competitive variety testing, a significant increase in the yield of green mass and dry matter was noted in the Pamyati Goncharova variety, the excess over the control of Omskaya 7 was 5.40 and 2.23 t/ha or 13.2 and 26.1 %, respectively. The average yield of seeds of varieties was 0.58 c/ha (0.50–0.72 c/ha), and the protein content was 19.27 % (18.46–20.08 %). The yield of seeds and protein content of all varieties in the first year of use of the herbage is much higher than in the second year of use, and in terms of the yield of green mass, a significant excess was noted in the second year of use of the herbage
