QTL analysis of potato tuber flesh color scores and map position of the candidate gene bch. A major QTL for tuber flesh color was found on chromosome 3 with strong correlation to the bch gene marker (red). Variation in expression of the bch gene is explained by the presence of a QTL on the same genetic position as the gene itself (cis-eQTL).
