Studies on Correlations and Path Coefficient Analysis in Clusterbean under Rainfed Conditions

Abstract

Correlation and path coefficient analysis for grain yield and its eomponents were studied in two environments in case of clusterbean (Cyamopsis tetragonloba (Linn.) Taub). Seed yield per plot and seed yield per plant were positively associated with number of pods per plant. Plant he~ght had negative association with number 01 branches while number of branches had positive association with number of clusters per plant in both the environments. Path analysis at genotypic level revealed that characters like higher number of pods per plant with more number of branches, 100 seed weight and number of seeds per pod with medium early maturing and medium dwarf plant type will give more seed yield per plot in seasons having early cessation of rains. In environment with relatively better distribution of rains, the plant type which have medium tall in plant height, late in maturity and high seed yield per plant together with more number of pods/plant, clusters/plant, seeds/pod and 100 seed weight will result in higher level of seed yield per plot in case of clusterbean.
