Abstract:

The present investigation on study of “Correlation and path analysis study in cowpea Vigna unguiculata (L.) Walp.] genotypes” was carried out during summer season in the year 2014-2015. The study was under taken on 30 genotypes of cowpea using randomized block design with three replication. The result on phenotypic and genotypic correlation coefficient revealed that pod yield per plot was significantly and positively correlated with number of branches per plant (0.7659), number of nodes (0.5523), pod length (0.3960), number of seeds per pod (0.2815), number of cluster per plant (0.550), number of pods per plant (0.547), number of pods per cluster (0.524), plant height (0.437) and protein content (0.2871). However, days for 50% flowering (-0.2081) showed significantly and negatively correlated with pod yield per plot. Other characters viz., days taken for first flowering (-0.1946), pod diameter (-0.1035) showed negative non significantly correlated with pod yield per plot. Path coefficient analysis of different yield and yield contributing traits on number of branches per plant, number of nodes per plant, number of cluster per plant, number green pods per plant, number of pods per plant, number of seeds per pod, pod weight (g), pod yield per plot and percentage of protein content exhibited positive direct effects on pod yield per plot these characters play a major role in recombination breeding and suggested that direct selection based on these traits will be rewarded for crop improvement of cowpea.
