experiment was conducted as an on farm trial in five different locations of Salem district during Kharif season of 2014 in chilli using hybrids TNAU Chilli Hybrid CO 1 and IIHR chilli hybrid Arka Meghana with a private hybrid US611 as check hybrid. TNAU Chilli Hybrid CO 1 showed moderate resistance to fruit rot disease with more number of marketable fruits per plant. Regarding yield attributes, TNAU Chilli Hybrid CO1 recorded 4.25t/ha of green fresh fruit yield and 1.57 t/ha of red ripe dry fruit yield. Whereas the yield of the other hybrid Arka Meghana was 2.57t/ha of green fresh fruit yield and 0.74 t/ha of red ripe dry fruit yield. The private check hybrid US611 recorded green fresh fruit yield of 2.67t/ha and red ripe dry fruit yield of 0.89t/ha. Regarding BC ratio, the TNAU Chilli Hybrid CO 1 given the highest value of 3.96, whereas it was lesser in private hybrid US611 (2.92) and least in (2.65) in Arka Meghana under Kolathur conditions of Salem district. This might be due to the less incidence of fruit rot in TNAU Chilli Hybrid CO 1 (22%) when compared to the other two hybrids (28% to 88%), which resulted in more number of marketable fruits and marketable yield as well as lesser production cost in TNAU Chilli Hybrid CO 1. Hence, performance of TNAU Chilli Hybrid CO 1 was found to be better for the chilli growing areas of Salem district especially in Kolathur Block.
