Abstract : An experiment was conducted to study the microbial spoilage of fruits from mango cultivars Raspuri, Alphanso and Dasheri during storage at 28-30°C and 50-60% relative humidity. The isolated postharvest spoilage causing microorganisms were identified as Rhizopus sp., Aspergillus sp. and Colletotrichum sp. Raspuri had the highest bacterial and fungal contamination in both external and pulp samples. Fruit decay was first observed on the fourth day after harvest in Raspuri whereas Alphanso and Dasheri were in good health until 12 days after harvesting. The rate of physiological weight loss (PLW) gradually increased as the storage period extended in all the 3 cultivars. However, the rate of PLW in Raspuri was high compared to Dasheri and Alphanso at 12 days after harvest.
