This article analyzed and evaluated the nutritional quality diversity of 528 mung bean samples from 16 regions in China, with the aim of enhancing the quality of mung bean germplasm resources and optimizing breeding efforts. The study found that the ranges of protein content, starch content, fat content, total polyphenol content and total flavonoid content in all tested samples were 16.14-29.19 g/100 g, 34.48-57.68 g/100 g, 0.67-1.34 g/100 g, 1.63-6.78 mg GAE/g and 0.59-2.83 mg RE/g, respectively; the coefficients of variation (CV) were 6.42%, 4.50%, 11.34%, 21.34% and 23.06%, respectively. Further cluster analysis of the nutritional components of mung bean from different regions showed that the nutritional quality of mung bean germplasm resources from different regions exhibited specificity, with Hubei region''s mung bean resources characterized mainly by high protein content; Jilin and Anhui regions'' mung bean resources characterized mainly by high starch content; Shandong, Hubei, Chongqing, Beijing, Xinjiang, Liaoning, Shanxi, Heilongjiang, Anhui and Hebei regions'' mung bean resources characterized mainly by high fat content; Chongqing region''s mung bean resources characterized mainly by high total polyphenol content; and Guangxi, Beijing, Anhui, Liaoning, Inner Mongolia, Jilin, Jiangsu, Shaanxi, Hubei, Hebei, Shanxi, Heilongjiang, Xinjiang and Shandong regions'' mung bean resources characterized mainly by high total flavonoid content. Correlation analysis indicated positive trends between longitude and protein (r=0.21), starch (r=0.30) and total flavonoids (r=0.40), while total polyphenols showed a negative correlation with longitude (r=-0.40) and fat content was negatively correlated with altitude (r=-0.23). These findings provide critical insights for mung bean quality breeding, high-quality germplasm screening, and sustainable development of the mung bean industry.
