Problems of phytoimmunity of grain crops in the Euro-Northeast of the Russian Federation and ways their solution

Breeding of grain crops for phytoimmunity in the FSBSU FASC Northeast is carried out conditions natural and artificial epiphytotics. Every year, more than 1000 samples winter rye, spring soft wheat, barley oats their own breeding from VIR collection are studied. In studies conducted on snow mold, root rot, powdery mildew, brown stem rust, septoria blight, fusarium head ergot; wheat – loose smut; net, dark blotch stripe disease, - red-brown blotch, crown panicle smut. Resistant detected infectious backgrounds will be included process as sources trait. With participation source genes, new varieties rye were created, Snezhana, Grefinya, others, which being studied at different stages. Long-term (2014-2020) provocative among material oats, revealed nonspecific resistance (6-9 points). They used crossbreeding programs with best to obtain high-yielding resistant biotic stressors hybrids that
