Abstract

In 1998 ten new varieties of COTTON (G.hirsutum & G.barbadense) crossed with two current commercial cultivars of Iran (Varamin and Sahel), these two cultivars used as female and tester parents. In 1999 F1 and parents seeds (20 hybrids and 12 parents) planted in field. The experimental design was randomized complete block with three replications. After analysis of variance for seed COTTON yield, earliness, number of bolls and boll weight, traits which had significant F became Line x Tester analysis, then GCA and SCA calculated for each varieties and also we estimated HETEROSIS for each crosses. Results showed that HETEROSIS for seed COTTON yield in interspecific crosses more than iteraspicific crosses. Among interspecific crosses, Varamin (G.hirsutum) T-14 (G.barbadense) cross had maximum HETEROSIS (MP=72.3%, HP=71.6%) and in interaspicific crosses was for Varamin (G.hirsutum) B-557 (G.hirsutum) cross (MP=30.68%, HP=13.01%). Varamin cultivar for seed COTTON yield and earliness, and Sahel cultivars for number of bolls and boll weight showed maximum and significant GCA than others. Varamin (G.hirsutum) T-14 (G.barbadense) cross showed maximum and significant SCA for seed COTTON yield. Evaluation of components of genetic variance explained that were dominance variance more than additive variance for all traits (seed COTTON yield, earliness, number of bolls and boll weight.
