Hyperspectral sensing was evaluated for non-destructive phenotyping of biomass (BM) and nitrogen (N) traits in winter wheat cultivars and breeding lines. Grain yield and grain N uptake were spectrally predictable and were more explained by aboveground BM and N accumulation than by allocation and translocation efficiency. Accumulative traits were spectrally better detected than the latter traits. In contrast to heading, the milk ripeness stage was most suitable. Red edge and water band indices are recommended for predicting N and BM traits, respectively, instead of the NDVI.
