Leaf-spotting diseases as a matter of damage of alfalfa breeding populations in an evident multifoliate phase in different cycles of phenotypic recurrent selection

Abstract

Alfalfa (Medicago varia Mart.) is the most important forage crop for considerable amount of regions of the Russian Federation and throughout the entire world. Assessment of the stability and resistance of alfalfa varieties to a complex of leaf-spotting diseases under various environmental conditions is important for breeding programs as a tool for selecting the best varieties and breeding samples
