The purpose of this study was to identify mungbean (Vigna radiata L.) cultivars with appropriate characteristics for labor saving culture (whole crop feeding and combine harvesting), and to investigate seed quality in the southern South Korea. Cultivar Dahyeon exhibited strong lodging resistance, excellent disease tolerance, and greater pod numbers per plant resulting in higher yield. Cultivar Owool and Keumseong, the two most common mungbean cultivars in Korea, exhibited lower yield than Dahyeon due to weaker disease tolerance or lower pod numbers per plant. Cultivar Samgang demonstrated higher seed starch content, Jangan, Nampyeong, and Keumseong exhibited higher crude protein content, and Sohyeon exhibited higher vitexin and isovitexin contents. However, no statistical differences were found among the cultivars in crude fat content. Unsaturated fatty acid ranged from 51.8 to 57.2%, with saturated fatty acid ranging from 36.2 to 40.3%. We detected five unsaturated fatty acids including linoleic acid (36.1 to 38.6%), linolenic acid (10.3 to 14.7%), and oleic acid (2.7 to 4.6%), and seven saturated fatty acids including palmitic acid (28.7 to 30.9%), stearic acid (2.9 to 4.1%), and arachidic acid (1.5 to 3.7%). There were significant differences between the cultivars in amylogram properties of seeds: the Nampyeong cultivar exhibited a lower gelatinization temperature; Dahyeon was higher in peak viscosity and breakdown; and Sohyeon, Nampyeong, and Dahyeon were lower in setback.
