Biological features pollination and formation of seeds of Medicago sativa L. their influence on the selection of high-performance origin material

Abstract

On the basis of the processed scientific papers, information was summarized regarding the biological characteristics of pollination and the formation of full-fledged seeds of Medicago sativa L. as an important forage entomophilous-cross-pollinated crop. Despite the high potential due to the biological characteristics of alfalfa, it is problematic to obtain a high yield of seeds, depending on the structural features of the flower, pollination, the passage of the embryonic period of ontogenesis and weather conditions during the flowering period.  The main reasons that affect the degeneration of seed buds are given. The ways of increasing the seed productivity of alfalfa varieties are proposed, in particular, a preliminary assessment, as well as selection, of the initial breeding material for the elements of seed productivity and the level of manifestation of autogamy
