The nature of inheritance of days to first fruit set, days to first picking, plant height, number of primary branches per plant, fruit size, flesh thickness, number of fruits per plant, average fruit weight, fruit yield per plant and number of locules was studied from a 10 parent diallel cross of Solanum lycopersicum L. None of the parents exhibited desirable gca effects for all the traits in individual as well as in pooled over environments. However, overall ranking of genotypes revealed that the parents Arka Vikas, KS-227, Roma, DVRT-I and DARL-63 exhibited significant desirable gca effects for most of the traits.
