Abstract

The article presents a study of the comparative characteristics of new promising lines of spring barley L1623 (nutans), L1505 (pallidum) and standards of varieties Suzdalets (nutans) and Leningrad (pallidum) on resistance to leaf diseases in various meteorological conditions of the growing season of 2012-2017. Assessment of leaf pathogens was carried out on a natural infectious background. Barley leaves were infested with powdery mildew (Blumeria graminis / DC), dark brown (Cochliobolus sativus Jto and Kurb) and mesh (Pyrenophora teres, Drechsl) patches. It was found that at an elevated air temperature and a large amount of precipitation (2013, 2014, 2016), the development of dark brown leaf spot reached 30-40%. In dry and warm weather (2012, 2015), the development of leaf pathogens was weak from 1 to 10%. The defeat of the net leaf spot in our experiments under any suitable conditions was 5-10% weak. The resistance to the dark brown patches of the new promising lines L1505 and L1623 is significantly higher than the standards. There were no significant differences in the degree of damage to the net spotting of these varieties.
