Evaluation of physiological and morphological traits conferring drought tolerance in cowpea
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.
