Plot level phenotypic data on University of Illinois soft red winter wheat breeding trials conducted at three locations in 2022 and 2023.

This data consists of plot level phenotypic data on grain yield and canopy spectral reflectance in soft red winter wheat collected by the University of Illinois wheat breeding program. Data are collected at six environments which include Urbana Illinois 2022, Urbana Illinois 2023, Neoga Illinois 2022, Neoga Illinois 2023, St. Peter Illinois 2022, and St. Peter Illinois 2023. Blue, green, NIR, red and red-edge reflectance values are recorded at multiple timepoints. A total of 2415 unique wheat lines were evaluated.
