Abstract

The research was conducted in 2011-2013 in the northern forest-steppe of the Tyumen region. The vegetation period of hulless barley samples ranged from 63 to 80 days. The samples with the length of stages - seedling-heading - 38-42 days and heading-ripening - 29-33 days produced the yield higher than the standard Omsk bare-grain 1 by 2.9-60.6%. The largest number of samples (56.6%) formed the eighth group where protein content was 15.1-17.0%; 30.2% of the samples appeared to be in the ninth group (17.1-20.1%), and 13.2% - in the seventh (14.0-14.9%). The highest average 1000 grain weight was observed in barley samples of the ninth group (42.8 g). The samples of the eighth group showed a lower characteristic value (40.3 g) while the samples of the seventh group where protein content was 14.0-14.9% had the lowest value (39.9 g). The average starch content in the samples of all groups was at the level of 58.8-60.5%. The limits of starch variations in barley samples were higher in the seventh group with high protein content. In the same group, the variation range of a trait was much higher (14.2%). The grain-unit g/cm3 increased on average from 6.5 (seventh group) to 6.7 (ninth group). The largest variation range was in the eighth group (2.0). A reliable positive correlation with yielding properties was found in the group with very high protein content (17.1-20.1%). The highest correlation coefficients were found by interrelations with: protein content (r=0.400), 1000 grain weight (r=0.687) and grain-unit g/cm3 (r=0.656). A reliable negatively-associated relationship was found between the starch content and the yield (r=-0.382). The following samples showed high resistance to stem rust (Puccinia graminis Pers), namely: Local (k-3115, Tajikistan), Local (k-3170, Tajikistan), Local (k-3772, Dagestan), Local (k-19709, Denmark), Local (to-21747, Dagestan). By lodging resistance at the level of 9 points, the following samples were distinguished, namely: Local (k-3038, Turkmenistan), Local (k-3165, Tajikistan), Local (k-3938, Mongolia), Buck CDC (k-30173, Canada). In the ninth group with high protein content (17.1-20.1) the local sample from Tajikistan (K-3770) formed standard starch content (60.8%). The local cultivars from Iran (k-3082) and Georgia (k-838) had the highest 1000 grain weight (52.7-55.5 g).
