Correlation and Path Analysis in Vegetable Cowpea
Author(s): 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 1st 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... View More»
