Present investigation was carried out with 47 genotypes including 11 lines, 3 testers and 33 F1s of brinjal. Best heterotic combinations over standard check for various characters were NDB 21 x PS and KS 356 x PU for days to 50% flowering (-32.65 and -28.57 %); PB 64 x PB 67 and NDB 21 x PB 67 for plant height (32.90 and 31.58 %); Punjab Sadabahar x PB 67 and PB 61 x PU for fruit length and diameter (51.62 and 200.42 %) respectively. The cross NDB 21 x PB 67 showed highest economic heterosis for most of the traits studied including the yield and yield attributing characters thus, this cross could be advanced to recover desirable segregants for the improvement of yield and yield contributing characters. On the basis of standard heterosis, it can be concluded that the heterosis breeding would be advantageous for the improvement of brinjal for yield and its component quantitative traits. The crosses NDB 21 x PB 67, PB 64 x PB 67 and PB 64 x PB 67 could be exploited as commercial hybrids as they demonstrated highly significant heterosis, over the standard cultivar, Pant Samrat.
