Evaluation of the morphological and yield traits in the new Varieties of cotton

Yield increasing and also the introduction of new varieties of cotton is one of the main goals of researchers. The important goal of this research was recognition of superior varieties in terms of yield. New and cultivated cotton genotypes including new varieties B557, T3, T2, SB35 and commercial cultivars like Moghan, Golestan and Sahel were evaluated in a randomized complete block design in Karkandeh Cotton Research Station. The results showed that T2 variety with 2160 kg/ha had the highest yield and SB35 variety with 1806 kg/ha had the lowest yield. Variety of B-557 with 75.8 % and varieties of T2 and T3 with 73.5 and 74.6 % were the earliest genotypes, respectively. Late maturity among varieties belonged to Armaghan and SB35 varieties with 53.8 and 55.7 %, respectively. The highest and lowest bolls weight were related to Golestan cultivar with 183.2g and T3 genotype with 153/8g, respectively
