Abstract:

The present investigation was focused on studying combining ability and heterosis breeding for yield, fibre quality and economically important traits designed among 19 parents and 84 hybrids developed through line x tester method. The analysis of variance indicated substantial variability among the experimental material for yield and fibre quality traits. All the characters were predominantly controlled by non-additive gene action except lint index. Four parents viz., TCH 1705-152, TCH 1705-101, TCH 1705-250, Surabhi were identified as very good general combiners. The hybrids, TCH 1705-152 x BS-1, ARBC 1301 x KC3, DSC-1302 x COD 5-1-2 and C 10-3 x TCH 1705-250 observed significant sca effects and four hybrids viz., TCH 1705-152 x BS-1, TCH 1705-101 x COD 5-1-2, TC H 1705-152 x Surabhi and VS-9-S11-1 x Surabhi were identified as the best hybrids well suited for exploitation through heterosis breeding with regard to per se, sca effect and standard heterosis.
