The expedition to collect and inventory indigenous sweet potato germplasm in Malaysia and Thailand in 1990 was planned by Agriculture, Forestry and Fishery Research Council (AFFRC), Ministry of Agriculture, Forestry and Fisheries (MAFF), Japan. The collection was carried out for 6 days from February 23 to 28, 1990 in Thailand and the joint exploration was done for 16 days from March 1 to 16, 1990 in Malaysia with the cooperative works between Malaysia and Japan. 2. Two of the three big sweet potato production areas, Chiang Mai area of North Thailand and Rayong area of South Thailand, were selected based on the report of SHIGA and IRIKURA (1982) and surveyed. The collection of sweet potato was made only at local markets in Chiang Mai area and at both of markets and fields in Rayong area. A total of 8 sweet potato tubers and 15 accessions of legume and others were collected as shown in Table 2. 3. For collecting sweet potato germplasm, Sabah and Sarawak have higher priority than other states of Peninsula Malaysia. The expedition sponsored by Tropical Agriculture Research Center, MAFF, Japan, was carried out in Sabah in 1989, and a total of 106 accessions were collected as shown in Table 3. The exploration was conducted mainly in Sarawak and partly in Sabah in 1990. 4. The exploration in Sabah was only done at Ranau, Pantai Barat. It was not surveyed in the previous expedition and was informed as the valuable area for collecting sweet potato. Data were collected from a total of 10 accessions (SB085-SB094) from Sabah, of which only 7 accessions were tuber samples. Weedy or semi-wild sweet potatoes were frequently found at Ranau area. 5. In Sarawak, a total of 56 sweet potato accessions were recorded-45 from the fields and 11 from markets. 37 accessions were tuber samples while vines were collected for 19 accessions, because plants were either too young or old and unmaintained, as shown in Tables 6 and 7.
