Assessment of genetic variability and character association in promising genotypes of Mungbean [Vigna radiata (L.) Wilczek]

Abstract

Character association study on seed yield and its component characters was made on forty genotypes in order to access genetic parameters namely variability, heritability and genetic advance. Simultaneously studies on character association for seed yield per plant and its component characters. The maximum variability was observed for number of branches per plant followed by biological yield per plant, seed yield per plant, 100 gm seed weight and number of pods per plant. Heritability estimates were found higher for all the traits except harvest index and 100 seed weight. High estimate of heritability coupled with genetic advance were observed for biological yield per plant, plant height and number of pods per plant for seed yield per plant, pods per plant and plant height indicating that these characters are least influenced by environmental variation. Seed yield per plant had significant and positive association with days 75% flowering, days to maturity, plant height, pods per plant, number of branches per plant, biological yield per plant and 100 seed weight.
