Abstract
The results of selection studies conducted at the Central Experimental Base of the V.R. Williams in the Non-Chernozem Zone of the Russian Federation are presented. Brief data on promising varieties of alfalfa created in the department of alfalfa breeding for the yield of green and dry mass, crude protein and other indicators are presented. Alfalfa varieties of a new generation adapted to local soil and climatic conditions have been created. Alfalfa is one of the best legume grasses for the preparation of high-protein feed. Alfalfa is a culture that is characterized by ecological plasticity, longevity, capable in many regions of Russia to solve the problem of eliminating the deficiency of vegetable protein in the diets of farm animals. It can be used as a legume component of grass mixtures on pastures and hayfields of the Non-Chernozem zone of Russia. The level of productivity and sustainability of fodder agrophytocenoses is determined by the competitiveness of species and varieties. Alfalfa varieties have a low competitive ability, do not withstand three or four times mowing, quickly fall out of the grass stand. It is known that the use of mineral nitrogen in meadow and field feed production is limited due to high energy costs in the production of nitrogen fertilizers. Therefore, the need for nitrogen in meadows and pastures should be met by legume-cereal grass mixtures, for which it is necessary to create new varieties of legumes, in particular alfalfa variable or hybrid.
