Under a Joint Research Agreement (JRA), the National Institute of Agrobiological Sciences (now the National Agriculture and Food Research Organization [NARO]), Japan, and the National Agriculture and Forestry Research Institute (NAFRI), Lao People’s Democratic Republic (Lao PDR) have collaborated since 2014 to survey plant genetic resources in Lao PDR. The main objective of this current survey was to collect samples of eggplant (Solanum melongena L.) and related crop species in the Sekong and Attapeu provinces, of southeastern Lao PDR. From 13th ? 29th of November 2017, we collected 200 samples, including S. melongena (182) and additional Solanum spp. (18). We found a wide diversity of eggplant landraces in southeastern Lao PDR, with a variation in fruit shape (flattened, globular, ovoid, pear shaped, ellipsoid, cylindrical), sizes (24 to 153 mm long), and colors (purple, green, white); spineless landraces were also common. The collected seeds were deposited at NAFRI, and a subset of the collection will be transferred to the Genetic Resources Center, NARO, Japan, as backup under the Standard Material Transfer Agreement (SMTA) of the International Treaty on Plant Genetic Resources for Food and Agriculture. Seeds from these genetic resources will be reproduced by self-pollination, and NAFRI staff will evaluate the characteristics of the plant material next season. Our plan is to evaluate the accessions’ morphological characteristics and resistance to Verticillium wilt, Fusarium wilt, bacterial wilt and nematodes in Japan.
