The spectra were collected from 3 raw-intact tubers, where the raw tubers were cleaned, peeled and cut cross-sectionally across the mid-section. Each piece was immediately scanned with the cut end facing the lense following the published SOP. Sensory data was collected by 12 trained panellists, who consumed small cubes of each cooked potato genotype and rated the overall liking of the samples on a 10-point hedonic scale ranging from 1 (dislike extremely) to 10 (like extremely), for each sensory trait per genotypes. Biochemical traits were collected following standard conventional procedures.
