Abstract:
Seven superior lines of tomato viz., Pusa Ruby, EC 620441, EC 914100, EC 914093, EC 914090, EC 620481 and EC 620452 were crossed with three testers (AVTO 1219, AVTO 1314 obtained from World Vegetable Center, Taiwan and one high yielding genotype Money Maker from Yates, New Zealand) in line x tester mating design to study the estimates of average heterosis, heterobeltiosis and standard heterosis for leven yield and yield contributing traits in tomato. The parent material was sown to generate F1 s during Rabi season 2018-19 and the parents along with F₁s were raised in early Summer 2019 in Randomized Block Design with three replications at college of horticulture, SKLTSHU, Telangana. The results revealed that analysis of variance indicated highly significant differences for all the characters, indicating that there is a variation between the characters studied. Top five cross combinations EC 620452 x Money Maker, Pusa Ruby x Money Maker, EC 620441 x AVTO 1314, Pusa Ruby x AVTO 1219 and EC 914100 x AVTO 1314 were found to be promising for fruit yield per plant. These heterotic hybrids found superior over better parent and three standard checks (Arka Rakshak, Arka Vikas and PKM-1) have the potential to be exploited commercially.
