The estimation of heterosis in 72 hybrids for yield and other 13 yield related component traits were studied following Line x tester design in chilli. Maximum heterosis (49.09%) for dry fruit yield per plant and fruit weight (21.70%) over standard check was observed in the cross Co-1x Byadagi dabbi and for plant height and number of primary branches the cross GPC-82xSinganahalli local. The hybrid Punjab LalxKDC-1 had more number of fruits per plant, while Puri redxLokur local and Puri redxKDC-1 were early for days to 50 per cent flowering. The hybrid G-3xVN-2 exhibited highest heterosis for fruit diameter and pericarp weight. For fruit length and number of seeds per fruit the cross Co-1xByadagi dabbi while, S-32xLokur local showed maximum standard heterosis for dry fruit yield per plant. The hybrids Co-1xByadagi dabbi (40.09%), Co-1 Lokur local (40.97%), G-3xLokur local (39.92%), Co-1xKDC-1 (36.10%), G-4xByadagi dabbi (34.19%) and Kunkaur-3xByadagi dabbi (32.66%) were considered most heterotic hybrids for yield and yield related components viz., number of secondary branches, number of fruit per plant, fruit length, fruit weight and pericarp weight.
