Abstract:

A 6x6 diallel cross excluding reciprocal of tomato was evaluated with parents for heterotic manifestation of yield and yield attributing characters. The heterosis over better parent (BP) to the extent of -14.64, -7.70, 15.84, 21.29, 15.30 and 38.91 per cent was recorded for days to first flowering, days to marketable maturity, average fruit weight, number of fruit per plant, harvest duration, yield per hectare, and plant height , 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. Three promising crosses viz., UHFT-9 x Solan Lalima, UHFT-10 x Solan Lalima, and UHFT-22 x Solan Lalima were identified for developing high yielding F1 hybrids/ varieties of tomato with many desirable horticultural traits.
