Heterosis and Inbreeding Depression for Yield and Quality Traits in Tomato (Lycopersicon esculentum Mill.)

Ten parental lines of tomato (Lycopersicon esculantum Mill.) were crossed in 10 x diallel mating plan barring reciprocals. The 45 F1 hybrids along with their parents and one standard check (Pusa Ruby) evaluated a randomized block design three replications. This study relevant that heterosis over the better parent, mid-parent, inbreeding depression was observed for all traits under study. Highly significant Days to first flowering (-18.35, -14.42 -3.30%), 50% fruiting (-13.41, -12.30 -6.71%), Fruit diameter (41.20, 46.07 35.57%), fruits length (49.20, 63.23 5.98%), Average fruit weight (59.26, 66.89 26.72%), Number per plant (135.19, 159.63 80.67%), cluster (54.55, 54.55 80.02%) total yield (123.71, 146.41 99.13%) better, mid parents, respectively considerable depression. most promising cross EC-165700 × EC-164563 appeared intensely noteworthy positive way parent plant. These Heterotic found superior have potential be exploited commercially.
