Abstract:
In the present investigation, ten tomato lines were crossed in half diallel mating design to produce 45 F₁ hybrids. The experiment was carried out at research farm, Department of Vegetable Science, College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha. Heterobeltiosis and standard heterosis were estimated for growth, fruit yield and quality traits in F₁ hybrids. The parental lines, viz. BT-22-4-1, BT-507-2-2 and BT-19-1-1-1 were found most promising for exploiting heterosis. Appreciable amount of heterobeltosis and standard heterosis was noticed for majority of the traits studied. Considering all the cross combinations individually, the hybrid combinations that out fielded their parents for a maximum number of components for heterobeltiosis and standard heterosis coupled with high per se values were; BT-19-1-1-1 x BT-22-4-1, BT-22-4-1 x BT-507-2-2 and BT-19-1-1-1 x BT-3. However, hybrids those performed better for yield parameters were not heterotic significantly for quality parameters.
