The present study was carried out on 32 tomato genotypes at Indian Agricultural Research Institute, New Delhi during 2021-22 with the objective to evaluate seed quality parameters of freshly harvested seeds from fully ripe tomato fruits. Among the seed quality parameters, germination percentage, shoot length, root length, total seedling length, seedling dry weight and seedling vigour index had been studied under the study. This study showed significant differences among 32 tomato genotypes for all the seed quality parameters, except root length. The germination percentage freshly harvested tomato seeds were ranged from 99% (H 410) to 4% (904117) across the genotypes. Highest seedling length observed in genotype H 412, whereas significantly lower seedling length demonstrated by genotype 904117. The genotype H 162 was found with significantly higher seedling dry weight, whereas genotype 904117 had significantly lowest seedling dry weight. Highest seedling vigour index I and seedling vigour index II observed in genotype H 410 and P. 120, respectively. Whereas lowest seedling vigour index had been observed in 904117 genotype. Among 32 tomato genotypes, H 391, H 410, H 412, and P. 120 were found to have significantly better seed quality after harvesting at fully ripe stage.
