Drought is increasingly becoming a serious challenge reducing common bean productivity. A study was conducted with the objective of evaluating common bean cultivars against different concentration levels of Polyethylene glycol which induces drought stress in radical length and root biomass to identify cultivars of common beans tolerant to drought stress and rank top performing accordingly. Complete Randomized Design with four replications and 50 treatments were employed in the laboratory experiment. Results showed that root biomass and radical length were maximum at control and decreased with an increase in PEG 6000 concentration. | Role of Polyethylene glycol in screening the common bean (Phaseolus vulgaris L.) cultivars for root traits under water stress conditions
