 ABSTRACT

Cowpea [Vigna unguiculata (L.) Walp] is highly drought tolerant and important crop for arid and semi arid areas. Twenty two genotypes of grain cowpea were evaluated for various morphological traits to study the main yield contributory traits during kharif 2018 under rainfed conditions. The high estimates of GCV and PCV were observed for seed yield per plot, number of pods per plant and plant height. High heritability accompanied with high genetic advance as per cent of mean revealed that the additive gene effect controls the inheritance of seed yield per plot, plant height and number of pods per plant. Highly significant and positive correlation were observed between seed yield per plot and plant height followed by days to 50% flowering, days to maturity and number of pods per plant indicated the importance of these characters for seed yield per plot. Highly significant and negative correlation was observed between seed yield per plot and 100 seed weight. The Path coefficient analysis showed that the plant height had the highest positive and direct contribution towards seed yield per plot followed by days to maturity and number of pods per plant indicating that selection for these characters would bring about improvement in seed yield of cowpea under rainfed condition.
