In this study, we examined the changes of fruit number and fruit weight according to the length of bearing branch of Actinidia arguta and identified the correlation the length of bearing branch and fruit characteristics. The fruit weight and the fruit number of A. arguta bearing branch which length are below 15 cm nd over 30 cm were 11.7 g, 4.3 and 12.3 g, 13.8, respectively. From the results, the bearing brach which length was below 15 cm must be removed in winter season pruning. The pruning experiment was conducted to examine the effects on fruit quality and yield of A. arguta. Total fruit yield of heavy-pruning was 14.3±1.5 kg/tree. The production of fruits over 15 g wight was 8.2±0.9 kg/tree, that of fruits between 10 g to 15 g was 4.0±0.7 kg/tree, and that of fruit below 10 g was 2.1±0.3 kg/tree, respectively. Average fruit yield of nonpruning was 26.7±2.1 kg/tree, fruit yield over 15 g, between 10 g and 15 g, and below 10 g were 2.5±0.5 kg/tree, 19.2±1.4 kg/tree, and 5.0±0.6 kg/tree, respectively. Distribution of high quality fruit (over 15 g) showed that non-pruning was almost 15~16 g but pruning was evenly distributed between 15 g and 20 g. According to the survey, The high quality fruit (over 15 g) would not be harvested if the winter pruning is not applied in the A. arguta cultivation.
