Abstract

Correlation and Path Analysis in Vegetable Cowpea

Gowri Mahalingam* and K. P. Sathiakumar

The genotypic and phenotypic correlations of green pod yield with different components were estimated from 50 genotypes of vegetable cowpea. The genotypic and phenotypic correlations agreed closely with each other. Yield contributing character number of pods per plant had positive and highly significant association with pod yield per plant at phenotypic level. Phenotypic interrelationship between days to 50 @ flowering and days to 1^st pod picking was negatively significant with green pod yield. The genotypic and phenotypic path analysis revealed the high to moderate direct effect of green pod yield per plant with number of pods per plant and pod length. Therefore, number of pods per plant and pod length was important component for improving green pod yield in vegetable cowpea.
