Infestation of winter barley varieties with leaf diseases in the southern part of the Rostov region The yearly assessment and analysis of leaf diseases is carried out on the infectious field and the plots of the laboratory for barley breeding and seed-growing of FSBSI ARRIGC named after I.G. Kalinenko. The study allows estimating the variety resistance in the natural conditions and extreme infectious conditions similar to epiphytotic disease. The article presents the results of immunological assessment of the varieties of local development and of other RI. The study of the disease manifestation was conducted during the years of 2014-2016. The varieties ‘Timofey’, ‘Erema’, ‘Vivat’, ‘Artel’ (of ARRIGC named after I.G. Kalinenko), ‘Gordey’, ‘Samson’ (KRIA named after P.P.
