Abstract

93 words

A field study was carried at Gwebi VTC to determine relationships among the morpho-physiological traits associated with drought tolerance in cowpea. Fifteen genotypes were planted in RCBD with three replications under two moisture environments, unstressed (US) and water stressed (WS). Thus, plants with reduced stomatal conductance and high chlorophyll absorbance should be selected in order to develop cowpea varieties tolerant to drought. Direct selection for number of pods per plant, harvest index and 100 seed weight would be effective under water stressed conditions since the positive correlationship was mainly due to direct effects.
