ABSTRACT
An investigation was carried out in F2 population of cross IT-38956-1 and KBC-2 and their parents to understand the association among the yield components and their direct and indirect effects on the seed yield. Grain yield per plant recorded significant and positive correlation with pod length, days to maturity, plant height, primary braches per plant, secondary braches per plant, pods per plant and seeds per pod.Pod length recorded highest magnitude of direct effects on seed yield per plant followed by secondary branches per plant and plant height. Hence, selection on the basis of pod length, days to maturity, plant height, primary braches per plant, secondary braches per plant, pods per plant and seeds per pod in segregating populations of cowpea will be more effective in the development of promising genotypes.
Key words: Correlation, Cowpea, Path analysis, Segregating population.
