Several experiments were carried out to develop a new cultivation system for strawberry suited to Japan’s cooler regions to enable June-bearing cultivars to produce high quality fruits in autumn: (1) Runner plants of cv. Nyoho were subjected to refrigerator-cooling, short-day cycles or shading treatments. Flowering was successfully advanced to early August depending on the treatment conditions. Factors affecting the treatment effectiveness were analyzed. (2) The development of fruit in cv. Morioka-16 varied considerably with the day, night and mean diurnal temperature conditions. Fruit Production with marketable value was not satisfactory at diurnal mean temperatures above 20℃, and the yield was reduced when the day temperatures exceeded 25℃. (3) Based on the results obtained, a new autumn cropping cultural system was proposed and the procedure for determining the optimal time of the processes was outlined.
