Abstract
The present investigation was conducted to evaluate the seed physiological parameters among twelve mungbean (Vigna radiata L.) genotypes. Significant differences were observed among genotypes for all traits studied, including germination percentage, root length, shoot length, seedling dry weight, seedling vigor index-I, seedling vigour index-II, and speed of germination. Genotype IC-436932 exhibited superior performance in most parameters, recording the highest germination (95.00%), seedling dry weight (0.85 g), seedling vigour index-I (3932.05), seedling vigor index-II (80.75), and speed of germination (49.66). In contrast, IC-252008 consistently showed the lowest values across these traits. The results highlight the existence of considerable genetic variability among the tested genotypes, suggesting potential for selection and improvement of seed quality traits in mungbean breeding programs.
