Abstract: An experiment was laid out in complete block design with three replications at the department of Botany, University of Sindh, Jamshoro, Sindh, Pakistan during 2007 for assessing the performance of commercial cotton cultivars viz., CIM-707, CIM-443, CIM-506, CIM-446, TH-3/83, FH-901, Chnadi-95 and Reshmi. The data was recorded on plant height, sympodia/plant, bolls/plant, boll weight and seed cotton yield/plant. Significantly maximum plant height (127.5 cm) and sympodia/plant (23.0) were displayed by variety TH-3/83 while the maximum seed cotton yield per plant (48.5 g) was shown by CIM-446 followed by TH-3/83. Maximum number of bolls/plant (18.56) and boll weight (5.11) were recorded for varieties FH-901 and Reshmi respectively. Correlation studies revealed that seed cotton yield/plant was significantly associated with sympodia/plant (0.379**), bolls/plant (0.509**) and boll weight (0.329*) which contributed 14.20%, 25.40% and 10.8% respectively toward seed cotton yield/plant. It is concluded that varieties CIM-446 and TH-3/83 showed overall better performance than other cultivars and may be recommended for commercial cultivation in the agro-climatic conditions of Jamshoro.
