The experiment on quantitative and qualitative effects of honeybee pollination on apple crop were carried out on European bee Apis mellifera L. and Indian hive bee Apis cerana F., by placing two colonies of each species in experimental apple orchards located at Padola (2200 m), Kalzar (2514 m) and Jarol (2648 m) areas in Shimla hills of Himachal Pradesh. There was no significant difference (P>0.01) in the fruit set in different experimental designs (honeybees pollinated flowers, open pollinated flowers and in control) in selfcompatible varieties of apple (Golden Delicious and Red Gold), but the differences in these experimental designs were significant (P<0.01) in selfincompatible varieties like Royal Delicious and Red Delicious. There was some difference in the fruit drops of selfincompatible varieties between open and honeybees pollinated flowers but it was not significant (P>0.01). In Golden Delicious and Red Gold, the qualitative pollination data showed that weight, length, breadth, volume and number of seeds per fruit developed were significantly maximum in honeybee pollinated flowers (P<0.01) and minimum in fruits developed under control experimental conditions in all the three orchards. Whereas, in Royal Delicious and Red Delicious varieties, the weight, length, breadth, volume and number of seeds per fruit were significantly more (P<0.01) in fruits developed from honeybees pollinated flowers than in fruits from open
