Abstract:
Brinjal is a self-pollinated, annual herbaceous vegetable crop. Brinjal is a diploid with 24 chromosomes which originated in India. The fruits of brinjal are widely consumed in various culinary preparations and are rich source of protective nutrients. In the present investigation, information on the magnitude of heterosis and combining ability and its interactions with locations were obtained for fruit yield per plant and its related components following half diallel mating design involving nine parents of Brinjal. The nine parents and their 36 F1s with one standard check were tested for thirteen characters under three environments viz., Navsari (E1), Varanasi (E2) and Waghai (E3) in a randomized block design with three replications. Analysis of variance in the individual environment as well as pooled over environments revealed considerable genetic variation among the parents and hybrids for all the characters. The existence of overall heterosis was evident from the significance of the comparison of parents vs. hybrids in all environments for all the traits. Hybrid viz., GOB-1 x Pusa Upkar, GAOB-2 x GOB-1, Pusa Upkar x GRB-5, GAOB- 2 x Swarna Mani and Swarna Mani x Pusa Upkar manifested high heterosis over the standard check with high fruit yield per plant. The hybrid crosses viz., GOB-1 × Pusa Upkar, GAOB-2 ×GOB-1, Pusa Upkar × GRB-5, GAOB-2 x Swarna Mani and Swarna Mani x Pusa Upkar manifested high heterosis over the standard check with high fruit yield per plant.
