Collaborative Exploration of Legume Crops and Wild Vigna Genetic Resources in Sagaing Region, Myanmar 2019

To collect legume genetic resources, a field survey was conducted in the Sagaing Region, Myanmar, from November 1 to 17, 2019. We concentrated on the collection of wild legumes belonging to genus Vigna. As a result, we collected a total of 43 seed samples from 23 survey sites and recorded three additional survey sites from where no seed samples could be collected. Collected seed samples consisted of 2 accessions of domesticated Glycine max (soybean), 2 of domesticated Lablab purpureus (hyacinth bean), 1 of domesticated Psophocarpus tetragonolobus (winged bean), 20 of Vigna angularis var. nipponensis (wild azuki bean), 6 of Vigna hirtella complex (wild Vigna), 6 of Vigna tenuicaulis (wild Vigna), 3 of domesticated Vigna umbellata (rice bean), and 3 of domesticated Vigna unguiculata (cowpea/yardlong bean). The collected seed samples have been primarily conserved in the seed bank of the Department of Agricultural Research in Myanmar, and the subset was transferred to the National Agriculture and Food Research Organization (NARO) Genebank in Japan under the Standard Material Transfer Agreement of the International Treaty on Plant Genetic Resources for Food and Agriculture. After the multiplication of seeds in Tsukuba Japan, the NARO Genebank plans to conserve them as distributable genetic resources for research, breeding, and training purposes for food and agriculture.

マメ科作物の遺伝資源を収集するために，2019年11月1日から17日にかけてミャンマー連邦共和国ザガイン地方域における二国間共同現地調査を実施した．調査は，特にササゲ属野生種遺伝資源を主対象として行われた．その結果，合計43サンプルの遺伝資源を収集し，それに加えて3地点の遺伝資源生育地情報を記録した．収集品の内訳は，ダイズ（Glycine max） 2点，フジマメ（Lablab purpureus） 2点，シカクマメ（Psophocarpus tetragonolobus）1点，ツルアズキ（Vigna umbellata）3点，ササゲ/ジュウロクササゲ（Vigna unguiculata）3点，野生アズキ（Vigna angularis var. nipponensis）20点, Vigna属野生植物（Vigna hirtella complex）6点，Vigna属野生植物（Vigna tenuicaulis）6点である．収集した遺伝資源は，原産国ミャンマーのシードバンクに保存し，そのサブセットをITPGRFAのSMTAを用いてNAROジーンバンクに移転した．NAROジーンバンクでは，本調査で収集した種子を用いて増殖・特性評価を行った後，食糧農業に関する教育・研究・育種利用目的のために配布可能な遺伝資源として公開予定である（https://www.gene.affrc.go.jp/index_en.php）．
