Abstract:
A laboratory experiment was conducted to study genetic variability parameters and character association of seed traits with 35 genotypes of mungbean under laboratory conditions during 2020 at College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner (Rajasthan). Highly significant differences were found among genotypes for all seed traits studied which indicates the existence of ample amount of genetic variability among genotypes and therefore, signifying the scope of selection for genetic improvement of mungbean. The high degree of genetic variability along with high heritability and high genetic advance as per cent of mean were estimated for water absorption capacity, water absorption index and porosity which reveals that these characters were under the control of additive gene action and therefore, form the basis of selection for mungbean improvement programme. Among seed traits, water absorption index and 100-seed weight had positive correlation with seed yield and directly contributed towards seed yield.
