The aim of this study was to determine drought response of thirty bean genotypes under glasshouse and field conditions (Kenya) during 1994. The experiment was laid in a Randomized Complete Block in split-plots design with three replications. Significant (p<0.05) genotypic differences in drought resistance were observed under moisture stress conditions. Significant interaction (p<0.01) between variety and moisture level were observed both in the glasshouse and in the field. Drought resistant genotypes showed high relative water content in stress environment as compared to susceptible ones. They also took relatively longer time to wilt, consequently showing low soil water content at wilting and lower biomass reductions under moisture stress conditions. A significant negative correlation was obtained between days to permanent wilting and relative water with biomass reduction. Relative water content was positively and significantly correlated to stomatal conductance and days to permanent wilting. Correlation between stomatal conductance and biomass yield reduction was not significant. The responses relative water content and stomatal conductance, in certain conditions, were recognized as beneficial drought resistance indicators and may be used as selection criteria in bean breeding programme.
