Different commercial cotton cultivars namely Bt. Cotton, BH-147, CIM-497, CIM-506, CIM-511 and Reshmi were studied for their comparative performance during 2012 at Nal district Khuzdar, Balochistan, Pakistan. The experiment was designed in a Randomized Complete Block Design (RCBD) and the genotypes were replicated thrice. These genotypes revealed statistically significant variations for all the studied traits. The cultivars CIM-506, CIM-511 and Bt. Cotton performed better in terms of seed cotton yield and number of sympodia. The cultivar Reshmi was best performing by giving heavier bolls (3.60 g), high ginning out turn (42.61%) and longest fiber length (29.60 mm). The correlation analysis manifested significant and positive association between seed cotton yield plant-1 and yield components. Cultivars CIM-506, CIM-511, Bt. Cotton and Reshmi gave more economical yield. On the basis of better varietal performance these varieties are recommended for gaining high yield per unit area.
