A diallel (8 x 8) analysis excluding reciprocal was made to assess the expression of heterosis  using 28 eggplant hybrids along with their 8 parents and 2 checks in a RBD with 3 replications for fourteenproductive traits namely, days to 50 % flowering, plant height(cm), primary branches per plant, secondary branches per plant, plant spread(cm2), fruit length(cm), fruit girth(cm), fruit weight(g), fruits per plant, fruit yield per plant(g), Total soluble solids (°Bx), Total phenol (mg g-1), Fruit dry weight ( mg/100mg) and Total sugar (%). The analysis of variance for all the characters revealed that parents were found to be highly significant for all the character studied except primary branches per plant and fruit yield per plant, similarly hybrids were also found highly significant for all the characters. Parents vs. hybrids comparison was found highly significant for all the characters studied except plant spread. Hybrids PLR-1 x GBL-1, PLR-1 x Doli-5, KS-224 x Doli-5 and PLR-1 x GJB-2 recorded high per se performance, significant heterosis over local check Surati ravaiya for fruit yield per plant, which may be utilized for further breeding programme.

Key words: Brinjal, Heterosis, fruit yield, Total phenol (mg g-1), Total sugar (%).
