Abstract: Ten genetically diverse parental lines, their 45 hybrids of brinjal obtained through half diallel and one standard check GABH 3 were studied to investigate extent of heterosis over better parent and standard check for fruit yield and its quality characters. The analysis of variance revealed hybrids differed significantly among themselves for all the characters under study. Appreciable heterosis was recorded over better parent and standard check for all the traits studied. In order of merit, significantly the highest heterobeltiosis and standard heterosis for fruit yield per plant was recorded with hybrid Doli 5 × Kashi Taru (63.54%) and GBL 1 × Doli 5 (48.28%), respectively. For the quality traits, the estimates of heterotic effects were low to moderate for all the characters except total phenol. The greater magnitude of heterobeltiosis for various characters indicated the differences in the performance between the parental lines and the hybrids. The moderate estimates of heterosis also suggested evidence for unidirectional dominance. Also, significant desirable heterotic effects for ascorbic acid and total anthocyanin (higher per se performance and standard heterosis) were also registered in the hybrid GBL 1 × Doli 5. The other top ranking hybrids were JBL 10-08-07 × AB 13-03, JBL 10-08-07 × GP-BRJ-216, JBL 10-08-07 x Kashi Taru and GAOB 2 × JBL 10-08-01 depicted higher and significant estimates of heterobeltiosis as well as standard heterosis for fruit yield per plant and desirable heterosis for different two to three quality traits. These crosses may be exploited for commercial cultivation and may also be advanced as those would likely to yield superior transgressive segregants for the improvements nutraceutical traits.
