  • In this study, the selected 789 lines having agronomic values out of over 2,500 mungbean (Vigna radiata (L.) Wilczek) germplasms, examined the 27 characters including hypocotyl color and leaf size of 401 lines in 2005 and of 388 lines in 2006, and analyzed the contents of vitexin and isovitexin in these mungbean germplasms. The average contents of vitexin and isovitexin in mungbean of the 401 lines used in 2005 were 8.71($1.1{\sim}13.4$) and 9.54($0.9{\sim}15.9$) mg/g, respectively, and the correlation coefficiency ($R^2$) of the contents of vitexin and isovitexin was 0.958. Nine lines including VC3890B were selected to be the ones containing high vitexin and isovitexin. The average contents of vitexin and isovitexin in mungbean of the 388 lines used in 2006 were 10.17($2.0{\sim}15.9$) and 10.64($0.2{\sim}17.6$) mg/g, respectively, and the correlation coefficiency ($R^2$) of the contents of vitexin and isovitexin was 0.958. Six lines including VC4096-2B-4-B-2-B were selected to be the ones containing high vitexin and isovitexin. The contents of vitexin and isovitexin were higher in the mungbean with larger leaves and longer ripening period out of the main characters.
