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. | Genetic variability heritability and genetic advance in eggplant Solanum melongena L. genotypes under normal and osmotic stress in invitro condition
