Abstract

To concentrate on the connections between early maturity and morph-phonological properties in cotton six varities of upland Cotton named varamin, early developing mutant (Mutagenese), 818-132, Bul-539, B-557 and Chirpan-539 were planted and a half diallel mating configuration included parents investigated in Cotton Research Institute, deputy of Varamin. Six parents and 15 hybrids in the next year were planted in a randomized complete block design with three replications. 17 components were collected and analyzed. Through stepwise regression analysis, early maturity was considered as dependent variable and other properties as independent variables. Accordingly, the production rate index, mean maturity data and plant height were liable for about 75 percent of early maturity changes.

Path analysis results uncovered that direct and negative effects of the production rate index (-0.6682) was viable in the development of the correlation with early maturity of (-0.809**). In any case, the roundabout impacts of production rate index on account of mean maturity data and plant height were unimportant. Direct effects of mean maturity data in correlation of this factor with early maturity (0.455**) was also significant (0.2462). Assessing the selection index revealed that in terms of early maturity, parent plant 1 (539-Bul) and hybrids 1*3, 1*4, 3*5 and 1*6 are superior to other hybrids. Changes in yield of varieties followed roughly 95% the maturity changes (r2 = 0.946). Generally speaking, results from this study illustrated that the production rate index, mean maturity data and the plant height could be utilized as an marker to choose early maturing varieties.
