Strawberries traditionally prefer the method of attracting runners generated from the mother plant, but a new raising seedling method is required due to the long seedling period and a large amount of labor input. This study was conducted to examine the possibility of changing to cutting propagation instead of the existing pinning propagation. The cutting propagation had a very high survival rate of over 97.2%, and the number of roots was 9.3 to 12.4 more than that of pinning propagation. Leaf growth was good in cutting propagation, and there was no difference in crown diameter. Fruit yields of cluster flowers 1 and 2 were 403.0 g for pinning propagation and 428.4 g for cutting propagation, showing no significant difference. The cuttings propagation had excellent quality of nursery plant and yield a lot of fruits, so it was possible to change to cuttings propagation when raising seeding strawberries. Depending on the cutting storage temperature and storage period, the survival rate after cutting was as high as 98.7%, and there was no difference in root growth between treatments. The roots number of the nursery plant of cutting propagation on the same day after cuttings was 34.9, the highest, and the weight of the crown was also heavier than the cutting propagation on the same day than the nursery plant stored on the 10th and 20th days. The storage temperature of strawberry cuttings was 3∼8℃, and the storage period was possible up to 20 days. The survival rate after terminal cutting and normal cutting propagation was 98.7%, and the diameter of the crown was 8.64mm for the normal cutting and 8.23mm for the terminal cutting. Root and leaf growth of nursery plant did not different between treatments. A terminal cutting and normal cutting were both possible as cutting materials. The number of leaves in the cuttings materials was corrected to a survival rate of 98.1% in the 1st and 2nd leaves, and the number of leaves was very low at 25.3% in the 0th leaf. The number of roots was 26.3 in 1 leaf, 2 leaf, and 23 in 0 leaf, depending on the presence or absence of leaf. The minimum number of leaves required for cutting propagation should be maintained at 1-2 to increase the survival rate and improve the quality of nursery plants. As for the number of roots by cutting date, cuttings on June 4 had the highest number of roots with 28.8 roots, and cuttings on July 9 had the lowest number of roots with 20.5 roots. The dry weight of the root was the heaviest at 1.05 g and 1.10 g in cuttings taken on June 4 and 11, respectively. The crown diameter was the largest at 11.76 mm and 11.36 mm in the cuttings on June 4 and June 11, respectively, and the smallest at 9.77 mm in the cuttings on July 9. The dry matter weight of the crown was the heaviest at 1.63 g in the cutting on June 4, and the pinning propagation was attracted to the cutting on June 25. It was thought that the date of cutting propagation should be done before June 18 to make a nursery plant of excellent quality of nursery plant.
