Cotton is the first and the main fibrous plant that it plays an important role in the creation of careers for individuals and development of textile industries in all over the world. Selection of a suitable cultivar for the West Azerbaijan region is important, since West Azerbaijan is the origin of cotton in Iran. This research conducted in order to evaluate of quantitative and qualitative traits of hopeful cotton cultivars under cold conditions in Urmia region. In this study eight cultivars evaluated with Varamin and Sahel as check cultivars in form of randomized complete block design with four replications in 2014 and 2015 (two cropping seasons) at Saatlou station of west Azerbaijan agricultural research, education, and extension organization. Results showed that K8802 cultivar is earliness cultivar and also is one of the best cultivars according to the traits such as the number of bolls per plant, sympodia per plant, final yield, seed cotton yield (yield of per plant), and qualitative traits. According to the combination analysis results, the interaction effect between treatment and year (treatment*year) for seed cotton yield, yield, and the number of bolls per plant at probability level (α=0.01) were significant. Stepwise multiple liner regression analysis revealed entrance of three variables, the number of bolls per plant, boll weight, and plant 596

Tissues of higher plants contain novel natural substances that can be used to develop environmental safe methods for insect control. In this study, ethanol extract from flowers of Verbascum cheiranthifolium Boiss. (Scrophulariaceae) was examined for their effect on mortality and progeny production against adults of Rhyzopertha dominica (F.) on two commodities, wheat and barley. The botanical extract was applied at five dose rates, which 0.25, 0.5, 1.0, 2.0 and 3% (w/v). Adults of R. dominica were exposed to the treated wheat and peeled barley at 25 degrees C and 65% RH and mortality was assessed after 24 h, 48 h, 7 day, 14 day and 21 day of exposure. Then all adults were removed and the treated substrate remained at the same conditions for an additional 45 day after this interval, the commodities were checked for progeny production. In two commodities mortality increased with the increase of dose and exposure interval. Results indicated that on wheat, mortality was 100% after 14 days of exposure at the highest dose rate. Whereas, in the same conditions mortality of adults on barley was 63%. Thus plant extract was more effective against adults of R. dominica on wheat than application of barley. Interestingly in two diets, complete suppression (100%) of the progeny production was observed in the treated wheat and barley than in control even in the lowest dose rate.
