Correlation and Path Coefficient Analysis for Seed Yield and Its Components in Mungbean (Vigna radiata (L.) Wilczek)

A study was carried out to study the association of it attributing traits in 30 diverse genotypes of mungbean duration Kharif 2009. The experiment as laid out a RBD with three replication row at spacing of 45×15cm. at Agricultural Farm, Rajoula, Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, Chitrakoot, Satna (M. P.). The estimates of correlation revealed that seed yield had highly significant and positive correlation for number of pods per plant, harvest index and number of cluster per plant while significant genotypic correlation for pod length. The correlation coefficient of seed yield per plant showed negative and highly significant correlation with days to flowering, plant height while days to maturity showed highly significant and negative correlation. Path coefficient analysis indicated that the highest positive direct effect on seed yield per plant was exhibited by harvest index, biological yield per plant at both levels, number of cluster per plant, days to maturity and number of pods per cluster at genotypic level and number of pods per plant and pod length at phenotypic level.
