An investigation was carried out in brinjal (Solanum melongena L.) to develop F1 hybrids with cluster bearing and glossy purple fruits. A total number of eight genotypes viz., Poiyur Purple, Ujala, Yendhal, Pusa Purple Cluster, PLR 1, Hybrid Derivative 1, Hybrid Derivative 2 and Hybrid Derivative 3 were chosen as parents and they were crossed in a ‘Full diallel mating design’ to get fifty six cross combinations. All the fifty six F1 hybrids and the eight parents were evaluated for thirteen characters. Based on the per se performance, the parent HD 3 was found to be the best for plant height, number of branches per plant, earliness, number of fruiting clusters per plant, number of fruits per plant, fruit yield per plant, whereas PPC followed by HD 1 and HD 2 excelled for number of flowers per cluster, number of fruits per cluster and fruit length. Among the hybrids, the hybrid PLR 1 x HD 3 registered the maximum per se for plant height, number of branches per plant, earliness, fruiting clusters per plant, fruit yield per plant and number of solitary fruits per plant followed by the hybrid PPC x HD 3 which had the highest number of flowers per cluster, number of fruits per cluster and solasodine content and HD 1 x HD 3 recorded the maximum number of fruits per plant. The hybrids PPC x HD 2 and Yendhal x HD 3, also showed favourable performance for yield and economic traits.
