Using wild oats and cultivated oats as research subjects, an experiment was conducted using wild population materials (Atl-03, Atl-05, Atl-06, Atl-08, Atl-11) and cultivated population materials (ITAO-32, ITAO-36, ITAO-38, ITAO-49, ITAO-50). Photosynthetic parameters including net photosynthetic rate, stomatal conductance, intercellular CO2 concentration, transpiration rate, and relative chlorophyll content (SPAD value), as well as agronomic traits such as plant height, panicle length, total tiller number, 1000-grain weight, and mean surface area of seed, were measured at heading stage, early grain-filling stage, late grain-filling stage, and maturity, respectively. The results showed there were significant differences in photosynthetic characteristics between wild oats and cultivated oats. The coefficients of variation of wild oats were higher than those of cultivated oats, but cultivated oats exhibited stronger and more stable photosynthetic performance. Furthermore, significant differences were also observed in agronomic traits between wild oats and cultivated oats. Correlation analysis indicated that net photosynthetic rate, flag leaf area, and SPAD value were all significantly positively correlated with 1000-grain weight. Among the wild populations, Atl-11 exhibited the optimal photosynthetic characteristics and agronomic traits; among the cultivated populations, ITAO-36 showed the optimal photosynthetic characteristics and agronomic traits, and both can serve as excellent germplasm resources.
