Abstract
Twenty eight hybrids of tomato developed using eight parents (PusaRohini, PusaGaurav, Roma, Cherry Orange, Selection-1, Taiwan, N-5 and C-10-15-27-3) in half diallelfashion were studied for estimation of heterosis for yield and its attributing traits. Hybrids PusaGaurav x Taiwan, PusaRohini x PusaGaurav and PusaRohini x Roma were found most promising for yield and its contributing traits. These hybrid exhibited heterosis to the tune of 48.14%, 44.47% and 73.41% over better parents and 83.43%, 76.78% and 74.24%, respectively over the check cultivar for fruit yield per plant. The cross combination PusaGaurav x Taiwan expressed highest significant standard parent heterosis and SCA estimates for yield and its attributing traits and it was identified for evaluation in multilocation trail and commercial exploitation.
