Seven cotton (Gossypium hirsutum L.) cultivars (one standard variety namely CRIS-134 and six advanced strains namely CRIS-19, CRIS-82, CRIS-83, CRIS-467 CRIS-468 and CRIS-5-A) were analyzed for quantitative characters. Mean performance of genotypes showed that the Cultivar CRIS468 produced numerically highest seed cotton yield and bolls per plant, the cultivars CRIS-82 and CRIS83 took significantly lowest number of days to open their first boll. Correlation studies revealed significant negative correlation (r = - 0.44) and (r= - 0.28) between character combinations such as, plant height with number of sympodial branches and plant height with Gining Out Turn (G.O.T. %), respectively. Further plant height showed significant positive correlation with characters such as number of days to open first boll (r = + 0.3), number bolls per plant (r = + 0.26) and average boll weight (r = + 0.29) indicating that the plant height is important in increasing seed cotton yield yet it may cause delay in maturity. While correlation study showed highly significant positive association of plant height with number of days to open first boll, number of bolls per plant and average boll weight.
