Abstract: A study was conducted in brinjal (Solanum melongena L. and Solanum aethiopicum L.) to estimate the magnitude of heterosis for growth, yield and its component characters. 28 F1 hybrids were derived from eight parents of brinjal genotypes. Biometrical design diallel (method-II) fashion was used for making crosses and all F1s along with 8 parents were evaluated during Rabi 2010-11 and 2011-12 using randomized block design, replicated thrice for both the years. Highly significant differences were observed among the genotypes for all the traits studied. For fruit yield per hectare the crosses BARI x PB-66, BARI x Pant Rituraj and PB-71 x Pant Samrat were found most heterotic hybrids over the years. These crosses could be exploited as commercial hybrids as they exhibited highly significant heterosis, over standard parent. The cross BARI x PB-66 showed highest economic heterosis for most of the traits studied including yield and attributing characters and may be utilized for commercial exploitation of heterosis for getting maximum yield.
