The present investigation was carried out in 73 eggplant genotypes to assess the nature and extent of genetic variability, heritability and genetic advance under normal (0% PEG-6000 as control) and osmotic stress condition (12 % PEG-6000) in germination phases in three replications in a completely randomized design. The observations on germination per cent, root, shoot and seedling length, fresh weight of seedlings and total dry matter were recorded on tenth day after incubation. Further, seed vigour, root to shoot ratio, root length stress tolerance index and plant height stress tolerance index were computed to understand the drought tolerance ability of the genotypes. The results of the analysis of variance for all the characters studied were found to be highly significant in both the conditions indicating the availability of huge variability. A high range of variation and high heritability coupled with high genetic advance was recorded for most of the traits. It indicates the broad genetic base and less environmental influence which specifies the predominance of genetic factor controlling variability. Hence, early generation selection schemes would be effective for improvement and there is an ample scope for isolation of promising lines from the present gene pool for drought tolerance.
