In order to save the management work on mother plants and to increase the yield within the year, the raising method of nursery plants with two buds originating from the crown of post-harvest stocks and their adaptability to forcing culture were investigated. When post-harvest stocks were potted with one or two leaves per bud and with a root length of 2 to 5cm, the viability of nursery plants with two buds was higher. Flower bud differentiation was accelerated during short days with tow temperature treatment. Flower bud differentiation, flower bud emergence and flowering nearly coincided in the two buds of a stock. When nursery plants with two buds were planted at the base of the crown depth, slanted and spaced 25 to 30cm apart, the yield was stabilized. Mulching before planting had no detrimental influence on the yield. The average fruit weight was reduced while the number of berries increased, so the yield within the year increased
