ABSTRACT
Seven diverse lines of tomato crossed with three testers in line x tester mating design to study the estimates of average heterosis, heterobeltiosis and standard heterosis for fourteen yield and yield contributing traits in tomato. The parent material was sown to generate F1 s during Rabi season 2016-17 and the parents along with F1s were raised in early Summer 2017 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. The two cross combinations EC 620494 x Arka Vikas and EC 620494 x Pusa Ruby were found to be promising for fruit yield per plant. These heterotic hybrids found superior over better parent and three standard checks have the potential to be exploited commercially.
Key words: Tomato, Heterosis, yield.
