Abstract:
A laboratory experiment was conducted to study genetic variability parameters and character association for seedling traits with 35 genotypes of mungbean under laboratory conditions at 30 °C and 40 °C temperature regimes during 2020 at College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner (Rajasthan). Highly significant differences were found among genotypes for all seedling traits studied except seed germination at 30 0C temperature which indicates the existence of ample amount of genetic variability among genotypes and therefore, signifying the scope of selection for genetic improvement of mungbean. Seedling traits like seedling dry weight, seedling fresh weight and seedling vigour index exhibited high degree of genetic variability along with high heritability and high genetic advance as per cent of mean at 40 °C. Therefore, screening of genotypes on the basis of seedling traits may be conducted at 40 °C. Among seedling traits, seedling fresh weight, seedling dry weight and seedling vigour index had positive correlation with seed yield at 30 °C and directly contributed towards seed yield.
