Under a Memorandum of Understanding, the National Institute of Agrobiological Sciences (Japan) and the National Agriculture and Forestry Research Institute (NAFRI), Lao People's Democratic Republic (Laos) have collaborated since 2006 to survey plant genetic resources in Laos. The main objective of the current survey was to collect accessions of eggplant (Solanum melongena L.) and related crop species from the northern provinces of Oudomxai and Phongsaly in Laos. From 9th to 25th November 2015, we collected a total of 124 accessions, including 101 S. melongena accessions and 23 accessions of other Solanum spp. We discovered a wide diversity of eggplant landraces in northern Laos, with variation in fruit shape (elongated, round, and flattened), length (21-600 mm), and color (purple, green, and white), and spineless landraces were popular. Seeds of these genetic resources will be produced by self-pollination, and NAFRI staff will evaluate the characteristics of the materials during the next season. The seeds produced at NAFRI will be shared between Laos and Japan. We plan to evaluate morphological characteristics and resistance of the accessions to Verticillium wilt, bacterial wilt, Fusarium wilt, and nematodes in Japan.
