Abstract: An investigation was carried out to assess the combining ability in eggplant genotypes using a diallel mating design (without reciprocal crosses) using 10 genetically diverse eggplant genotypes namely, Pusa Purple Long, Pusa Uttam, Punjab Sadabahar, Selection-2, Mukta Shree, Type -3, Pusa Upkar, BR-112, Azad-331 and Udaipur Local. The experiment was set up in a randomized complete block design (RCBD) with 3 replications during autumn-winter season of 2011-12. General combining ability studies revealed that Pusa Purple Long was the best combiner for major flowering contributing characters including days to anthesis of first flower, days to 50 per cent flowering and days to first fruit picking and Pusa Uttam was best combiner for yield and yield attributing traits including fruit yield per plant, fruit weight and number of fruits per cluster in all the environments. However, the estimates of specific combining ability showed the desirable SCA effects in crosses Pusa Purple Long x Pusa Uttam was suitable for heterosis breeding since it expressed desirable values for six important characters in all the environments. The hybrids Pusa Upkar x Azad-331and Pusa Uttam x Selection-2 could be considered as next best hybrid suitable for heterosis breeding.
