Tree canopy form, planting density and training affect availability of solar radiation in the orchards. Favourable effect of sunlight exposure on the anthocyanin accumulation on the fruit surface has been reported by several workers, but information regarding the colour development on mango is meagre. The present investigation was undertaken to study the influence of light regime on the fruit colour and total soluble solids in the fruit. Fruits developing at various positions of the tree canopy (exposed to various radiation levels) were sampled for recording information on their surface colour and TSS in the fruit pulp. Fruit surface colour was estimated by tristimulus colourimeter using Hunter scale. The study revealed that the attenuated direct sunlight was unfavourable for surface colour development and total soluble solid content of the fruit. The mean L value which represents the lightness of the fruit surface was signifivantly more in the fruits developing at higher solar radiation fraction. Fruits developing under shade exhibited less TSS and comparatively poor colour as compared to exposed fruits. The studies show that canopy management practices are important for good quality fruits in mango.
