This study aimed to assess their phenotypic and nutritional diversity to explore their potential for breeding and meeting dietary needs. Twenty-nine local landraces and one control cultivar (\u2018Qingsu 7\u2019) were evaluated for key agronomic traits, yield components, nutritional traits, and isoflavone profiles, using hierarchical clustering, principal component analysis (PCA), and correlation analysis. Substantial phenotypic diversity was found, with the germplasm classified into four groups. First pod height and effective pods per plant were highly variable. Nutritional traits showed low variability for crude protein but high diversity for crude fat, soluble sugars (dominated by sucrose), vitamin C, and free amino acids. Total isoflavone content in dry seeds varied widely, with genistin, daidzin, and daidzein as the main forms. \u2018Xiangshui Maodou\u2019 had high free amino acids and vitamin C, \u2018Heiyan Susudou\u2019 showed superior soluble sugar content, and two landraces exceeded 1500 \u03bcg\/g DW total isoflavones. The landraces possess rich phenotypic diversity and nutritional diversity. This germplasm represents a valuable resource for breeding programs to enhance crop quality and address global nutritional demands.<\/jats:p>","DOI":"10.3390\/foods15132382","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T14:33:06Z","timestamp":1783089186000},"page":"2382","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Comprehensive Evaluation of Agronomic Traits and Nutritional Composition in Summer-Sown Vegetable Soybean Varieties from Shanghai, China"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-6401-9351","authenticated-orcid":false,"given":"Biting","family":"Cao","sequence":"first","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lihua","family":"Zhu","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5537-9108","authenticated-orcid":false,"given":"Jiaqi","family":"You","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Yuan","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weihong","family":"Gu","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongjuan","family":"Yang","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duo","family":"Lv","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingzhu","family":"Li","sequence":"additional","affiliation":[{"name":"Forest and Pomology Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0713-3872","authenticated-orcid":false,"given":"Chaohan","family":"Li","sequence":"additional","affiliation":[{"name":"Shanghai Key Laboratory of Protected Horticultural Technology, Protected Horticultural Research Institute, Shanghai Academy of Agricultural Sciences, Shanghai 201403, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,3]]},"reference":[{"key":"ref_1","first-page":"1821","article-title":"Diversity of morphological, agronomic, and quality traits of soybean (Glycine max L.) and their potential as edamame","volume":"56","author":"Hijrah","year":"2024","journal-title":"SABRAO J.
