Abstract

An experiment was conducted to estimate the combining ability in 8 cultivars of G. hirsutum L. General combining
ability (GCA) mean squares for testers were significant for boll number only, whereas GCA for lines and SCA
for hybrids were highly significant for boll number and seedcotton yield. The larger proportion of variance for GCA
revealed that the nature of gene action was predominantly additive for these traits. S-12 for boll number and seedcotton
yield. CRIS-7 A for sympodia, boll number and seed cotton yield, and CYTO-127 and CYTO- I30 for seed cotton
yield proved to be the best general combiners. The crosses S-12 x CYTO-127 and BH-36 x CRIS-54 manifested
highly significant SCA effects for boll number and seed cotton yield per plant.
