Collaborative Survey and Collection of Vegetable Genetic Resources in Myanmar, 2019 and 2020

Exploration and collection surveys were conducted from November 2 to November 15, 2019, and from December 26, 2019, to January 7, 2020, under a collaboration between the Tokyo University of Agriculture (TUA), Japan and the Department of Agriculture Research, Myanmar. The first survey was conducted in the northern part of the Sagaing region, and the second in the southern part of Sagaing region, the mountainous area of Nay Pyi Taw, and Shan State. For both surveys, genetic resources were collected from farmlands, farm houses, and local markets. In November 2019, 27 accessions were collected, including 17 samples of Brassica juncea, 4 of the B. oleracea L. Alboglabra group, 3 Brassica sp., and 3 Raphanus sativus L. specimens. From December 2019 to January 2020, 104 samples were collected: 34 Brassica juncea, 7 of the B. oleracea L. Alboglabra group, and 7 Raphanus sativus L. Root and tuber crops, such as Dioscorea spp. and Colocasia esculenta L. Schott, as well as one Xanthosoma sagittifolium, Amorphophallus spp., accounted for 15, 29, and 12 accessions, respectively. The collected genetic resources were divided between the Myanmar Seed Bank and the TUA for the PGRAsia Project, and 50 % were exported to Japan as per the Standard Material Transfer Agreement. The exported seeds and tubers will be multiplied and evaluated in Japan and will be available at the NARO Genebank, Japan for research, breeding, and educational purposes.ミャンマー連邦共和国において，農業畜産灌漑省農業研究局（DAR）と東京農業大学の共同で”Mohn Nyin” と呼ばれるカラシナを中心としたアブラナ科野菜およびイモ類の探索収集を行った．１度目の調査は2019年11月１日から15日にかけてザガイン地方域北部において，2度目の調査は2019年12月26日から2020年1月7日にかけてザガイン地方域およびマンダレー地方域，シャン州において行った．その結果，Brassica juncea 51点，Brassica oleracea L. Alboglabra Group 11点，Brassica sp. 3点，Raphanus sativus L. 10点のアブラナ科野菜遺伝資源およびDioscorea spp. 15点，Colocasia esculenta (L.) Schott 28点，Xanthosoma sagittifolium 1点，Amorphophallus spp. 12点の計131点が収集された．収集品は2分し，一方はミャンマーシードバンクで，他方はSMTA に基づき日本に導入された後，農業・食品産業技術総合研究機構遺伝資源センターにて保存される．Figure 1点, Table 2点, Photo 20
