The composition of pigments in mango peel and pulp is an important quality determinant due to their role in consumer attraction and nutrition of the fruit. An experiment was conducted to evaluate the coloring parameters of F1 progenies of Alphonso×Vanraj cross combination. The study revealed that compared with the female parent Alphonso (17.11 mg/100 g), the male parent Vanraj showed significantly higher peel total anthocyanin content (29.74 mg/100 g). In contrast, the peel carotenoid content of Alphonso was twice as that of Vanraj. The total anthocyanin and carotenoid contents in the peel of the progenies ranged from 6.01-29.74 mg/100g FW and 5.04-45.08 mg/100 g FW, respectively. Peel had significantly higher carotenoids compared to the pulp. Correlation studies revealed the associations between color coordinates and pigments. h° (hue angle) was strongly positively correlated with chlorophyll and carotenoids of the peel and negatively correlated with peel anthocyanins. Thus, hue angle can be used as a non-destructive method to predict the pigments of mango peel. Principal component analysis revealed clusters within the progenies on the basis of the observed pigments and color coordinates. This study elucidates the associations between of color coordinates and pigments in the peel and pulp of mango highlighting the indirect selection of progeny.
