Hyperspectral Reflectance Data and Agronomic Traits Can Predict Biomass Yield in Winter Rye Hybrids

Winter rye (Secale cereale L.), a potential alternative biogas substrate, is traditionally bred for grain yield. Thus, our objective was to evaluate the possibility to predict dry matter yield combining vegetation indices derived from visible to NIR spectral data as a proxy for agronomic traits. A total of 404 elite rye hybrids were tested for grain yield, and a subset of this comprising 274 hybrids were also tested for dry matter yield over 2...
