This is a report for the Plant Genetic Resources in Asia project for the collaborative collection and conservation of plant genetic resources in east Cambodia under the agreement between the Cambodian Agricultural Research and Development Institute (CARDI) and the Genetic Resources Center, the National Agriculture and Food Research Organization (NARO), Japan. A field survey was conducted in five provinces (Kandal, Tboung Khmum, Kratie, Mondul Kiri, and Kompong Chan) in Cambodia from October 28 to November 8, 2019. We mainly focused on vegetable amaranths and collected a total of 75 germplasms, including 51 of amaranths (10 Amaranthus blitum, 20 A. spinosus, and 21 A. viridis), 19 of eggplants (Solanum melongena), 2 of turkey berries (S. torvum), 1 of S. violaceum, 1 of tomato (Lycopersicon esculentum), and 1 of Trichosanthes cucumerina. The seeds were divided equally: half were conserved in CARDI, and the other half was transferred to the gene bank at NARO.
