Abstract :

Recognition and using of appropriate cultivars in production process and quantitative and qualitative improvementof crops yield have a special impact. In this research, nine imported cotton genotypes including hybrids and promising cultivars along with Varaminas conventional cultivar were evaluated based on randomized complete block design with four replications in Moghanregion for one year. In each plot,cotton genotypes were planted in sixlines with 8 meter length at intervals of 20 × 80 cm. Quantitative traits such as plant height, boll number and weight, one week before harvest and  yield, early maturity were recorded after harvesting. G-43347 and G-43259 cultivars with average yield of 4785 and 4625 kg/ha, respectively had the highest yield and G-43347 and Opal cultivars with 84 and 83% early maturity, respectivelywere the most early maturingcultivars. Therefore, G-43347 and Opal cultivarswould be suitable candidates to be replaced for current conventional cultivars in Moghan region. Varamincultivar as check 71% early maturity and yield of 3992 kg/ha could not compete with new studied cultivar emphasizing using G-43347 and Opal cultivarsin this region.
