The present investigation entitled “Methods of Pollination Influencing Fruit Development Stages of Exotic Apple Cultivars at High Altitudes of Kashmir Valley” was carried out at “Advanced Centre for Horticulture Development Zainapora, Shopian” during 2012 and 2013. The experimental material (varieties) i.e. treatments were Gala Mast, Royal Gala, Early Red One, Law Red Rome, Scarlet Spur, Oregon Spur, Braeburn, Ginger Gold, Red Gravenstein, Golden Delicious and Red Gold. Observations were made to evaluate the difference in response of these Washington brought genotypes under Kashmir valley and their fruitfulness for horticulture industry. Among the methods, natural selfing recorded the highest initial fruit set 1.48% in Red Gold as compared to zero percent recorded in some other varieties. Under open pollination method, the initial fruit set was highest 88.35, and 87.00 percent, and final 33.30%, and 34.41% in Red Gold cultivar. The lowest initial fruit set 65.77 and 67.71 percent and final fruit set (14.32 and 17.24%) observed in Red Gravenstein and Ginger Gold. The maximum fruit drop (79.64 and 77.56 percent) observed in the cultivar Scarlet spur and Ginger Gold. The minimum fruit drop 62.57 and 61.16 per cent recorded in Golden Delicious followed by 62.30 and 60.44 per cent in Red Gold. In fruit maturity, the cultivar Golden Delicious took significantly more number of 185 and 183 days after full bloom (DAFB) to reach the harvestable stage. Red Gravenstein took minimum number of days (95 and 96 DAFB) to reach harvestable maturity during both years, respectively.
