Genetic variability, character association and path analysis in clusterbean (Cyamopsis tetragonoloba (L.) Taub)
2013
Clusterbean (Cyamopsis tetragonoloba (L.) Taub) is commonly known as Guar, is a valuable arid legume crop grown for its gum, vegetable and also fodder. Very few efforts have made to understand the association of various yield components and their direct and or indirect influence on yield of clusterbean. In the present study forty two genotypes of clusterbean selected from various genetic backgrounds with diverse geographical origin were used to study the association pattern among morphological traits and direct and indirect effect of these traits on productivity is also discussed. Number of pods per plant, cluster per plant, pods per cluster, and branches per plant had positive and significant correlation with seed yield per plant, whereas, cluster per pod, 100-seed weight, followed by seed per pod had positive and greater direct effects on seed yield per plant and pod length, branches per plant and days to maturity had negative direct effect on seed yield per plant.
