Abstract:

A 8x8 full diallel cross of tomato was evaluated with parents and cheks for heterotic manifestation of yield and yield attributing characters. The heterosis over commercial check-2 to the extent of 107.08, 59.79, -13.59, 174.70 and 13.58 per cent was recorded for plant height at 60 DAP, number of branches per plant 60 DAT, days to fifty per cent flowering, number of fruits per plant and average fruit weight respectively. The crosses showing heterosis for yield per plant were not heterotic for all the characters under study. The heterosis for yield was generally accompanied by heterosis for yield components. Promising crosses for yield per plant are Vaibhav x PKM-1, PKM-1 x Anagha and Arka Sourabh x Anagha, for average fruit weight (more than 70 g), Vaibhav x Arka Saurabh and Vaibhav x PKM-1 crosses found promising with high standard heterosis. The yield and yield components indicated the role of both additive and non-additive gene effect in governing these traits.
