The present investigations entitled “Studies on Floral biology, Pollination and Fruit set in Kiwi fruit [Actinidia deliciosa (A. Chev.)] under hilly conditions of Uttarakhand” was carried out at the near the P.G. Girls hostel at College of Horticulture, Uttarakhand University of Horticulture and Forestry, Bharsar, from March to May 2016. The different parameters for floral biology, pollination and fruit set were recorded on the basis of time period. The results showed that kiwi plant shows simple dichasium type of bearing habit. Flowering period starts from first week of second week of April to first week of May with total duration of flowering of 32 days to complete 8 stages of floral bud development. Maximum anthesis of flower occurs between 6am-8am in male flowers and 8am-10am in hermaphrodite flowers. Maximum anther dehiscence takes place 15 minutes after the anthesis. From the above findings, it is concluded that for crop improvement and other programmes April third week to May first week is preferred under hilly conditions of Uttarakhand.
