Abstract

In the present study the experimental material consisted of six parents and 15 F1s produced in halfdiallelmating design. Analysis of variance for combiningability exhibited the significance for gca and sca effects for all the characters studied. The non-additive effects played a more important role than additive effects. CA-32 was good general combiner for green fruit yield per plant. CA-8 was good general combiner for number of fruits per plant which can be exploited in breeding programme. The maximum sca effect for green fruit yield per plant in F1 generation was recorded in the cross of CA-23 x CA-32. The hybrids CA-23 x CA-32, CA-8 x CA-23, CA-8 x CA-32 and CA-6 x CA-23 were best specific crosses for several characters on the basis of specific combining ability effect. The results suggested exploitation of hybrid vigour in chilli.
