NIRS Calibration for sensory attributes on raw fresh intact sweetpotato at CIP, Uganda.

The document highlights the NIR prediction models developed using spectra of raw intact sweetpotato roots collected across different genotypes and CIP trials in Uganda, in 2023. The process of sample and spectra collection has been documented earlier (https://doi.org/10.18167/agritrop/00708). Sensory reference data was collected according to documented protocols (Nakitto et al. 2022). Reference values (n=306 samples, 102 genotypes) and spectra were collected in first season of 2023 (2023A). Orange color intensity has consistently been modelled with higher accuracy (R2=0.88).
