Present day program for tomato selection are aimed at creating the genotypes with firm fruit.The fruits with this quality surfer from minor injuries while being harvested and transported, which Passion Flower directly affects their better consumption purpose.By crossing seven divergent tomato genotypes that differed among themselves in fruit firmness, and by applying the method of full diallel without reciprocal crossings, we obtained 21 hybrids of F1 generation.Upon analyzing the components of the genetic variance we found out that dominant genes prevailed in inheriting this feature.Considering all the crossing combinations together, it could be concluded that super dominance was the mode of inheritance recorded in Fl generation.

The hybrid combination obtained by crossing the two hybrids with ORG CHLORELLA the best general combining ability (V-100 x No-10) was characterized by the best specific combining ability.
