Abstract:Drought stress is a major problem for mungbean production and the drought tolerance evaluation is a priority research for mungbean in whole world. The germination rate of four accessions of mungbean germplasm resources was tested with 5 PEG-6000 density. The results showed that 21.8% (-0.9MPa) of PEG-6000 is the suitable density for screening drought resources at bud stage for mungbean. The drought resistance of 113 accessions of mungbean germplasms resources were evaluated with -0.9MPa PEG-6000 solution. Correlation analysis results showed that relevant germination energy, relevant germination rate, relevant hypocotyl length, relevant radical length, relevant total length, relevant fresh biomass, relevant dry biomass, relevant germination index and relevant vigor index were closely related to the drought resistance. Based on the average membership function analysis, the highest drought resistant germplasm, Dangdijidou (C0000626) and 16 drought resistance germplasms were identified and recommended to be used in the drought tolerance improvement for mungbean breeding.
