Perspectives of breeding of vegetable crops of Fabaceae family to bean yellow mosaic virus (Potyvirus, Potyviridae) resistance in the conditions of Moscow region

In the context of climate change phytomonitoring of the prevalence of the most common viral pathogens on the crops becomes even more important, because during the last decades the harmfulness of those pathogens, in particular Bean yellow mosaic (BYMVjhas grown in intensity. The causative agent as the most members of Potyvirus genus, has a wide range of host plants belonging to various families including Fabaceae. In Russia the virus was for the first time identified in the south of the Far East, where in the middle of XX century the massive damage of clove, lupine, sweet pea, pea, bean and Russian bean was observed. The distribution area of BYMV considerably expanded after advancement of heat-loving leguminous crops towards north. During the last years epiphytotics were reported in the planted crops of kidney bean (Phasйolus vulgбris L.), and Russian bean (Faba bona Medik. var. major Harz.) under conditions of temperate continental climate of nonchernozem belt in the RF...
