Abstract:

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. However, vigour index is a stable character and can be considered as a useful tool to screen drought tolerant genotypes. Besides, non-parametric selection for yield and drought tolerance was scored based on the mean performance of each character. Based on vigour index and non-parametric selection, the genotype ML 267 was found to be drought tolerant with high yield.


Keywords: Mungbean, PEG, Germination percentage, Root length, Shoot length, Vigour index.
