4. 雖因各地環境，及氣候等因素影響塊根生產力，但就春季全省區域試驗，或春季試作結果觀察，沖繩100號對於全省適應性極大，在本省三分之二的試驗地區沖繩100塊根產量每公頃為6.900－31.000公斤左右，超過在來種約10％－20％左右，全省各地之製簽量則均高於在來種約 40％－80％左右。
1. The sweet potato variety, Okinawa No.100 was found from the progenies by crossing the Chifu as female parent with Chaochou as male at Okinawa Agric-ultural Experiment Station in Japan in 1928. It was designated in 1934 and introduced from Japan to China in 1941 and brought to chiayi Agricultrual Experiment Station from Nanking Central Agricultural Experiment Station in 1948.
2. Characteristics of the plant are as follow:
The leaf is green with tri-cleft incition. The vine is dark purple with the tender part remaining green. The tuber skin is light violet and the flesh is yellow. The root is shortly fusiform in shape with sulcate.
3. Okinawa No. 100 is an early matured and wet tolerant variety, but it is not tolerant to dry condition and cold weather. It is not influeuced by heavy rainfall and high temperature during the spring season. So it is very adapted to spring planting,
4. Although the tuber yields were affected by different climate and soil conditions in various localities, it is widely adapted through this island in accordance with results in both spring regional test and spring planting trial. The yield is from 6,900－31,000 Kilogram per hectare and 10－20% highe than the local varieties at two-third of the experimental plantations in this island, Furthermore, the dry chip yield of this variety is 40-80% higher than the check varieties in all the experimental plantations through the whole island.
5. Okinawa No.100 was considerably resistant to the Fusarium disease and sweet pota-to scab disease caused by Sphaceloma batatas Sawada.
