Heterosis study is the one method widely utilized for the selection of superior cross combinations. Since the exploitation of heterosis has become commercially feasible and more attention is being paid to study the phenomenon of hybrid vigour in this crop. A study was made to assess the nature and extent of relative heterosis, heterobeltiosis and standard heterosis using forty eggplant hybrids along with their respective parents. Among the 40 hybrids, the hybrid obtained from the cross Alagarkovil Local x Annamalai (L4xT1), Palamedu Local x Punjab Sadabahar (L5xT3), Palamedu Local x EP 65 (L5xT4) and Keerikai Local x KKM 1 (L7xT2) were found to be suitable for heterosis breeding. Per se performance of parents revealed that the lines Alavayal local (L1), Sedapatty local (Green) (L2) and the tester Annamalai (T1) were identified as the good parents for further breeding programme to exploit high yield along with low incidence of pest and diseases.
