ECOLOGICAL STUDY OF WINTER BARLEY VARIETIES IN THE FSBSI ARC “DONSKOY”

Barley is a grain crop, which has a wide range of economic use. Barley productivity greatly varies according to cultivation areas, therefore ecological variety-testings are carried out to reveal variety response to various soil-climatic conditions.  It allows identifying the varieties with good adaptability to definite soil-climatic conditions. The purpose of the work is to study the main economic-valuable traits of winter barley varieties in the southern part of the Rostov region. The study was conducted on the crop rotation fields of the department for barley breeding and seed-growing of the ARC “Donskoy” in 2015–2017. The objects of the study were 25 winter barley varieties of different ecological and geographical origin. There were identified the varieties with a complex of economic-valuable traits and properties. The varieties ‘Hiscory’, ‘Explorer 7’, ‘Wintwalt’ and ‘Explorer 3/2’ showed a complex resistance to leaf diseases.  The varieties ‘Timofey’, ‘Master’, ‘Erema’, ‘Vivat’, ‘Tigr’ (ARC “Donskoy”, Russia), ‘Scala’, ‘Meredian’ (Germany), ‘Explorer 2’, ‘Explorer 6’, ‘Саpten’ (France) showed a large grain content per head. There were identified such large-kerneled varieties as ‘Timofey’ (ARC “Donskoy”, Russia), ‘Scala’ (Germany), ‘Explorer 1’, ‘Explorer 2’, ‘Explorer 6’, ‘Explorer 8’, ‘Wintwalt’, ‘Capten’ (France) with 45.1–50 g; the varieties ‘Meredian’, ‘Hiscory’ (Germany), ‘Explorer 3’, ‘Explorer 4’, ‘Explorer 5’, ‘Explorer 7’, ‘Explorer 3/2’, ‘Explorer 4/2’, ‘Bronskajli’ (France) with more than 50 g. The varieties ‘Master’, ‘Tigr’ (ARC “Donskoy”, Russia), ‘Gordey’ (RCG named after P.P. Lukyanenko, Russia), ‘Scala’, ‘Casino’ (Germany), ‘Explorer 6’, ‘Explorer 7’ (France) showed their early ripeness.
