Screening of mungbean (Vigna radiata L. Wilczek) genotypes against water stress mediated through polyethylene glycol

Thirty one mungbean (Vigna radiata L. Wilczek) genotypes were screened for drought tolerance under laboratory conditions in CRD using PEG 6000 at different concentrations of -0.3 MPa, -0.6MPa and -0.9MPa. The genotypes showed reduction in germination percentage and shoot length and increase in root length under water stress condition. Screening of genotypes based on single morphological parameter appears to be limiting due to inconsistency in growth responses of different seedling parts.
