Research area of University College of Agriculture, University of Sargodha was used for this experiment from 15-November 2016 to 15-March 2017. Three varieties of linseed (Punjab, Chandani, and PR24) were grown in predefined areas with division six plots. To count the number of pollens, the pollen collector placed in front of the hives at entry of box. The number of bees leaving and returning to the hive counted three times in a day at morning, noon and evening sessions (at 8:00 am, 12:00 pm and 4:00 pm) and the number of pollens counted in every session. Also, seed setting of linseed crop as impacted by foraging activity of honey bees were checked. Non-parametric tests used to evaluate and compare the obtained results. Friedman test applied to estimate honey bee amount during the day at different timings (8:00 am, 2:00 pm and 4:00 pm). The results indicated that maximum numbers of bees leave the box and come back in Chandani variety as well this variety showed the higher results in seed setting.
