Collaborative Exploration of Plant Genetic Resources in Southern Cambodia, 2019

Under the Plant Genetic Resources in Asia (PGRAsia) project, National Agriculture and Food Research Organization (NARO) and Cambodian Agricultural Research and Department Institute (CARDI) have conducted several collaborative explorations in Cambodia since 2014. As part of the project, we surveyed and gathered plant genetic resources in Southern Cambodia from October 1 to 10, 2019. In the survey, we explored the genetic resources in 14 districts of Southern Cambodia in Svay Rieng, Pery Veng, Kandal, Phnom Penh, Kampong Speu, Preah Sihanouk, Koh Kong, Kampot, and Takeo provinces and collected 85 accessions from farmers’ storages, back yards, or fields. The accessions corresponded to Solanaceae (34), Cucurbitaceae (35), Fabaceae (8), and Amaranthaceae (8). Among 34 Solanaceae accessions, 29 were from C. frutescens. As the present study was conducted in a flood-prone area, vegetable cultivation during the rainy season was low, and flood-tolerant luffa and hyacinth bean were considered important vegetables for cultivation. The collected seeds were divided equally, and half the seeds were conserved at CARDI in Cambodia. The other half was transferred to the Genetic Resources Center, NARO, Japan, under the standard material transfer agreement.Plant Genetic Resources in Asia (PGRAsia)プロジェクトの下，研究開発法人 農業・食品産業技術総合研究機構（NARO）とカンボジア農業開発研究所（CARDI）は，2014年からミャンマーにおける植物遺伝資源探索を共同実施している．その一環として，2019年10月1日から10日までカンボジア南部の植物遺伝資源の探索・収集を実施した．探索は，Svay Rieng，Pery Veng，Kondal，Phnom Penh，Kompong Speu，Preah Sihanouk，Koh Kong，Kompot，Takeo県を含むカンボジア南部の14地区で実施し，農家で保存している種子の他，庭または畑の植物から合計85系統を収集した．これらにはナス科が34系統，ウリ科が35系統，マメ科が8系統そしてヒユ科が8系統含まれ，そのうち，ナス科ではトウガラシが29系統収集されたが，いずれもC. frutescensに属するものであった．今回の探索地域は洪水多発地域であったため，雨季は通常の野菜栽培が少なく，洪水時でも栽培可能なヘチマ類やフジマメが重要な野菜とされていた．収集した遺伝資源種子は，SMTAによりカンボジアのCARDIと日本の農研機構遺伝資源センターのジーンバンクに均等に分配された．Figure 1点, Table 3点, Photo 7点, Sample Photo 89
