Under a Memorandum of Understanding, the National Institute of Agrobiological Sciences, Japan and the National Agriculture and Forestry Research Institute, Lao People's Democratic Republic (Laos), have collaborated since 2006 to survey plant genetic resources in Laos. The main objectives of the current survey were to collect accessions of eggplant (Solanum melongena L.) and other target Solanaceae (crop species) in the Houaphan and Xiengkhouang provinces of northern Laos. The survey was conducted from 24 November to 10 December 2014. A total of 134 accessions were collected: 112 of S. melongena, 9 of other Solanum spp., and 3 of Capsicum spp. We discovered large eggplant diversity in the northern part of Laos: the landraces had diverse fruit characteristics such as shape (elongated, round, or slightly flattened), size, and color (purple, green, white, orange or yellow). Moreover, it was very interesting that spineless landraces were popular in this area. Seeds of these genetic resources will be produced by self-pollination, and the HRC staff will evaluate the characteristics of materials collected in this survey in the next season. Seeds produced in the HRC will be shared between Laos and Japan. We plan to evaluate morphological characteristics and resistance to soil-borne diseases, Verticillium wilt, bacterial wilt, Fusarium wilt, and nematodes in Japan.
