The studies on heterosis were carried with four male sterile lines namely; ms7, ms8, ms9, ms10 and 18 diverse pollinators as tester by using line × tester crossing programme. The 72 F1 hybrids were produced and evaluated along with 22 parental lines during summer 2009 and rainy season 2009 in Randomized Block Design. Observations were recorded on nine quantitative traits during both the seasons. Highly significant variances for all the traits indicated the sufficient variability in the parental material for all the characters under study. The performance of F1 hybrids was much better than the mean performance of parents during both the crop seasons. Appreciable heterosis was observed in all the characters, except flower weight in summer and plant height in rainy season.
