This study evaluated leaf gas exchange and chlorophyll fluorescence traits in seven soybean cultivars grown under irrigated (IR) and rainfed (RF) environments in the Mississippi Delta. At the beginning seed stage (R5), key physiological parameters\u2014including net photosynthetic rate (A), stomatal conductance (gs), intercellular CO\n                    <jats:sub>2<\/jats:sub>\n                    concentration (Ci), transpiration rate (E), instantaneous water\u2010use efficiency (WUE\u2009=\u2009A\/E), instantaneous carboxylation efficiency (ICE\u2009=\u2009A\/Ci), electron transport rate (ETR), and photosystem II quantum yield (\u03a6PSII)\u2014were measured. Seed yield was determined at physiological maturity (R8). Under irrigated conditions, A and ICE showed the strongest positive associations with SY, whereas under rainfed conditions, WUE emerged as the primary predictor of yield. Cultivars DS 25\u20101, Dyna\u2010Gro 4516\u00d7, LG03\u20104561\u201014, and P37A78 exhibited consistently superior physiological performance across both water regimes. These findings highlight the importance of integrating gas exchange and fluorescence\u2010based traits into trait\u2010based selection strategies. However, given the limited number of cultivars, location, and growing seasons evaluated, these results should be interpreted as indicative rather than definitive. This study provides one of the first field\u2010based comparisons of photosynthetic traits across maturity groups III\u2013V within the Early Soybean Production System, offering insights into physiological indicators of yield stability under contrasting water regimes.\n                  <\/jats:p>","DOI":"10.1002\/pei3.70178","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T12:29:21Z","timestamp":1782908961000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Photosynthetic Traits Underlying Yield Differences in Irrigated and Rainfed Soybean Systems in the Mississippi Delta"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7983-4662","authenticated-orcid":false,"given":"Srinivasa R.","family":"Pinnamaneni","sequence":"first","affiliation":[{"name":"Western Colorado Research Center\u2010Grand Valley, Colorado State University  Fruita Colorado USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7231-0719","authenticated-orcid":false,"given":"Isabel M.","family":"Lima","sequence":"additional","affiliation":[{"name":"USDA\u2010ARS, Southern Regional Research Center, Commodity Utilization Research  New Orleans Louisiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean A.","family":"Beacorn","sequence":"additional","affiliation":[{"name":"USDA\u2010ARS, Southern Regional Research Center, Commodity Utilization Research  New Orleans Louisiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,1]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/aob\/mcab141"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2018.12.471"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11099\u2010013\u20100021\u20106"},{"key":"e_1_2_11_5_1","unstructured":"Berrada A.
