The experiment was carried out at Vegetable Research Station, Junagadh Agricultural University, Junagadh, Gujarat during rabi season of 2017-19 to study performance of nine lines and four testers into thirty-six tomato hybrids for fruit yield and its component traits by Line x Tester analysis. The analysis of variance for seventeen characters showed significant differences for all the genotypes indicating that experimental material had sufficient genetic variability for all the characters studied. Among 36 hybrids, 9 and 12 hybrids manifested significant desirable heterobeltiosis and standard heterosis for fruit yield per plant. The heterobeltiosis for fruit yield ranged from -70.26 to 206.04 % while standard heterosis ranged from -66.32 to 189.32 %. The cross JTL-15-02 × Punjab Chhuhara exhibited the highest desirable heterosis over better parent followed by JTL-15-05 × DVRT-2. These hybrids exhibited desirable heterosis for important yield attributes suggesting that the heterosis for marketable yield was associated with heterosis for component characters.
