LeafPoseNet and wheat flag leaf angle image datasets (Zhao County, Shijiazhuang City, 2022–2023 and 2023–2024 growing seasons)

All 221 common wheat accessions were planted in Zhao County, Hebei Province, China (37°50′N, 114°49′E) in the 2022–2023 and 2023–2024 wheat growing seasons.After flowering, the main tillers of five representative wheat plants were randomly selected from the three middle rows of each plot for measuring the flag leaf angle (FLANG). FLANG images were captured on May 8–9, 2023, and May 17–18, 2024. In addition, the source code and pretrained weights of LeafPoseNet, along with the supplementary data referenced in the manuscript, have been made publicly available.
