The data on performance of high and low pollen hoarding colonies revealed significant differences with respect to different colony parameters. Ranking obtained by different colonies with respect to colony strength, brood area, pollen stores, honey stores, pollen stores and hygienic behaviour were scored as per their performance. The main criteria for selecting colonies with high pollen hoarding and low pollen hoarding tendency was average pollen stores. The three high pollen hoarding colonies (H-4, H-5 and H-9) were those which scored 3 to 4.50, whereas low pollen hoarding colonies (L-4, L-6 and L9) scored 4 to 4.50 for average pollen stores and bee foragers. The low pollen hoarding & high pollen hoarding colonies also showed significant seasonal variations with respect to various colonies characteristics. Number of incoming bees with pollen loads at hive entrance was significantly more (51.94 bees per minute) in high pollen hoarding honeybee colonies as compared to low pollen hoarding colonies (42.82 bees per minute). Apple pollen preference in colony number G-2 from general stock showed highest preference for apple pollen foraging with 18.78 per cent of apple pollen loads. Colony H-4 recorded minimum percentage of apple pollen load. Out of nine, 7 colonies collected significantly same percentage of apple pollen. These studies suggest that selection efforts for bees with the preference for apple pollen could be combined with selection for pollen hoarding to get a strain of honeybee with higher preference for apple pollen foraging.
