Abstract:
An investigation was carried out with an objective to determine the ideal harvesting stage for fruit quality of two important mango varieties viz. Ratna and Mallika under Kerala conditions. The experiment was carried out at the Department of Post-Harvest Technology, College of Agriculture, Vellanikkara, Thrissur, Kerala during 2019- 21.Flowers were tagged during fruit set and observations on physical characters, biochemical parameters of fruit and stone were taken at different stages of growth along with organoleptic evaluation for fruit quality. It is understood from the current study that the ripe maturity stage in cv. Ratna is at 110 days after fruit set (DAFS) with accumulation of 1107.75 HU and in cv. Mallika it is 140 DAFS with accumulation of 1507 HU in Kerala. Both the cultivars reported better physical and biochemical parameters like TSS, sugar, ascorbic acid, total carotenoid, β-carotene, and crude fibre with less acidity, total phenol, total chlorophyll and maximum marketable fruits with good quality parameters.
