Interspecific hybrids of hirsutum and barbadense are known for high productivity and fibre quality. Estimation of combining ability of a line or inbred is useful for predicting its useful as parent in hybrid breeding. The analysis of general and specific combining ability aids in identification of potential parents for production of superior hybrids. General and specific combining ability effects were estimated for eight lines, four testers and their 32 hybrids. | Combining ability studies in cotton interspecific heterotic group hybrids G. hirsutum x G. barbadense for seed cotton yield and its components
