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-1 x Byadagi dabbi and for plant height and number of primary branches the cross GPC-82 x Singanahalli local. The hybrid Punjab Lal x KDC-1 had more number of fruits per plant, while Puri red x Lokur local and Puri red x KDC-1 were early for days to 50 per cent flowering. The hybrid G-3 x VN-2 exhibited highest heterosis for fruit diameter and pericarp weight. For fruit length and number of seeds per fruit the cross Co-1 x Byadagi dabbi while, S-32 x Lokur local showed maximum standard heterosis for dry fruit yield per plant. The hybrids Co-1 x Byadagi dabbi (40.09 %), Co-1 Lokur local (40.97 %), G-3 x Lokur local (39.92 %), Co-1 x KDC-1 (36.10 %), G-4 x Byadagi dabbi (34.19 %) and Kunkaur-3 x Byadagi 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.
