The Cambodian Agricultural Research and Development Institute (CARDI) conducted an exploration and collection of plant genetic resources in Southwestern Cambodia in 2022 in cooperation with the National Agriculture and Food Research Organization (NARO), Japan. The exploration was conducted within the framework of the Plant Genetic Resources in Asia (PGRAsia) project funded by the Ministry of Agriculture, Forestry, and Fisheries, Japan. The team mainly explored cucurbitaceous vegetables in four provinces of Southwestern Cambodia (Kampot, Kampong Speu, Koh Kong, and Preah Sihanouk) and collected a total of 85 samples, including 22 accessions of pumpkin (Cucurbita moschata), 30 of melon (Cucumis melo), 5 of cucumber (Cucumis sativus), 3 of watermelon (Citrullus lanatus), 1 of wax gourd (Benincasa hispida), 9 of eggplant (Solanum melongena), and 15 of chili pepper (Capsicum spp.). The seeds of each sample were divided into two parts: half were conserved in CARDI and the other half were transferred to the Research Center of Genetic Resources, NARO, using the standard material transfer agreement (SMTA)., カンボジア農業研究開発研究所(CARDI)と国立研究開発法人 農業・食品産業技術総合研究機構(農研機構)が連携して,2022年にカンボジア南西部において植物遺伝資源の探索・収集を実施した.この探索は,農林水産省委託プロジェクト研究「海外植物遺伝資源の民間等への提供促進」(PGRAsiaプロジェクト)の予算により実施した.本探索ではカンボジア南西部の4つの州(Kampot, Kampong Speu, Koh Kong, Preah Sihanouk)において,合計85点の遺伝資源を収集した.その内訳はニホンカボチャ(Cucurbita moschata)が22点,メロン(Cucumis melo)が30点,キュウリ(C. sativus)が5点,スイカ(Citrullus lanatus)が3点,トウガン(Benincasa hispida)が1点,ナス(Solanum melongena)が9点,トウガラシ(Capsicum spp.)が15点である.収集した遺伝資源の種子の半分はCARDIに保管し,残りの半分は標準材料移転契約(SMTA)に基づいて農研機構遺伝資源研究センターに送付した., Figure 1点, Table 3点, Photo 6点, Sample Photo 84点

- Abstract
Genetic diversity of Cambodian melons was evaluated by the analysis of 12 random amplified polymorphic DNA (RAPD) and 7 simple sequence repeat (SSR) markers using 62 accessions of melon landraces and compared with 231 accessions from other areas for genetic characterization of Cambodian melons. Among 62 accessions, 56 accessions were morphologically classified as small-seed type with seed lengths shorter than 9 mm, as in the horticultural groups Conomon and Makuwa. Gene diversity of Cambodian melons was 0.228, which was equivalent to those of the groups Conomon and Makuwa and smaller than those of Vietnamese and Central Asian landraces. A phylogenetic tree constructed from a genetic distance matrix classified 293 accessions into three major clusters. Small-seed type accessions from East and Southeast Asia formed clusters I and II, which were distantly related with cluster III consisting of large-seed type melon from other areas. All Cambodian melons belonged to cluster I (except three accessions) along with those from Thailand, Myanmar, Yunnan (China), and Vietnam (“Dua thom” in the northwest), thus indicating genetic similarity in these areas. In addition, the Cambodian melons were not differentiated among geographical populations. Conomon and Makuwa were classified into cluster II, together with melon groups from the plains of Vietnam. The presence of two groups of melons in Southeast Asia was also indicated by population structure and principal coordinate analysis. These results indicated a close genetic relationship between Cambodia and the neighboring countries, thus suggesting that Cambodian melons are not directly related to the establishment of Conomon and Makuwa.

amaranth ,breeding ,melon ,pumpkin ,variation ,maize - Abstract
Cambodia is an important center of vegetable crop diversity, including varieties of Cucurbitaceae and Solanaceae crops, and could provide useful genetic resources for crop breeding programs. Field exploration was conducted in northern Cambodia to collect vegetable genetic resources based on cultivation methods and characteristics. A total of 71 samples of six crops, including 28 melons, 22 pumpkins, 11 amaranths, eight maize, one cucumber, and one Solanaceae species, were collected from 36 sites in four provinces. These samples were collected at new sites, with the exception of one amaranth sample, Amaranthus spinosus, which was a different Amaranth species collected from a previously visited site. Based on interviews with farmers and previous reports, we obtained the following overview: common local names for pumpkins, melons, and maize; distinct names for amaranth species; cultivation occurs during the rainy season; comparatively less frequent use of fertilizer and agrochemicals for pumpkin and melon; and frequent cultivation of amaranths in backyard gardens. The observed morphological traits showed variations comparable to those reported in previous studies, such as plant height and panicle length in amaranth, plant height variation among three species of amaranth, and cob length variation in maize. The overview and morphological information provided useful references in the study of Cambodian genetic resources as well as for the management of the collected species. The seeds were divided between the CARDI and the gene bank at NARO., カンボジアはウリ科作物やナス科作物などの野菜の多様性中心の一つで,同国における作物遺伝資源は育種計画において有益な遺伝資源として活用できる.そこで,カンボジア北部において遺伝資源探索を実施し,野生遺伝資源とともにそれら遺伝資源の栽培方法の情報や特性評価情報を収集した.71点の野菜遺伝資源が4つの州における36地点から収集された.その内訳は,28点のメロン,22点の日本カボチャ,11点のアマランサス,8点のトウモロコシ,それぞれ1点のキュウリおよびナスである.収集した試料は,1点を除いて,新規の地点から収集された遺伝資源であり,また,残る1点のアマランサスにおいて種名が従前の探索で収集されたアマランサスとは異なっていたことから,新規の試料であった.日本カボチャ,メロン,アマランサスおよびトウモロコシについて農家からの聞き取り調査によって,呼称がアマランサス種間で異なること,これらの作物が主に雨季に栽培されること,日本カボチャやメロンの栽培においてはほとんど肥料や農薬を施用しないこと,および,アマランサスは家の庭において栽培されていることがわかった.アマランサスの3つの種間における草丈,葉や穂の長さの違い,ならびにトウモロコシにおける雌穂長といった形質変異は既報においても認められた.既報や本調査における4つの作物についての概要や形質の情報はカンボジアの遺伝資源に関する研究や本調査で収集された遺伝資源の管理・利用に有益だと考えられた., Figure 1点, Table 3点, Photo 4点, Sample Photo 70点
