In 2019, the JRA was extended until 2023 under a newly signed addendum. The main objective of the present survey was to collect the samples of eggplant (Solanum melongena L.) and related crop and wild species from the Savannakhet Province of southern Lao PDR. During November 5 to 20, 2019, we collected 163 samples of S. melongena (n=140) and additional Solanum spp. (n=23). We found various eggplant landraces in southern Lao PDR and observed variations in fruit shape (flattened, globular, ovoid, obovate, or ellipsoid), size (7.9 to 95.1 mm long), and skin color (purple, green, or white). Over half of the collected landrace accessions were spineless. The collected seeds are deposited at NAFRI for further evaluation of their general characteristics and reproduction via self-pollination in the next season. Following seed reproduction, a subset of the collection will be transferred to the Genetic Resources Center, NARO, Japan, under the Standard Material Transfer Agreement in accordance with the International Treaty on Plant Genetic Resources for Food and Agriculture. In Japan, NARO will evaluate the resistance of these accessions to Verticillium wilt, Fusarium wilt, bacterial wilt, powdery mildew, and nematode infection as well as their morphological characteristics., 本報告は,独立行政法人農業生物資源研究所とラオス農林省国立農林業研究所(NAFRI)との間で2014 年に締結された共同研究協定(JRA)および2019年に追加された補遺に基づいて行われたラオス国における2019年のナス遺伝資源の調査報告である.調査は,2019年11月5~20日にかけて実施された.今回,我々はラオス国南部地域であるサワンナケート県を調査し,ナス栽培種Solanum melongena 140点およびナス近縁種を23点の合計163点の種子サンプルを収集した.当該地域におけるナスには、果皮色や果形に一定程度の多様性は確認されたものの,そのほとんどは小さな球形の緑色果実であり,これまでに実施した北部や南部での調査に比べると,多様性に乏しい傾向にあった.一方で,とげの有無については,他の地域と同様に半数程度の在来品種がとげなし性であったことは興味深い.収集した遺伝資源の種子は,NAFRIにおいて保存されるとともに,自殖による再増殖の後,特性調査が行われる予定である.再増殖された種子は、「食料及び農業のための植物遺伝資源に関する国際条約」(ITPGRFA)に基づく定型の素材移転契約(SMTA)により農研機構遺伝資源センターに分配され,重複保存される予定である.日本では,土壌伝染性病害虫への抵抗性などの特性が調査され,有望な育種素材が検索される予定である., Figure 2点, Table 4点, Photo 30点}, pages = {57--79}, title = {ラオスにおけるナス遺伝資源の共同探索,2019年}, volume = {36}, year = {2021}, yomi = {ミヤタケ, コウジ and ウサミ, ヒトシ and ヨコタ, マコト and SENGOUNKEO, Phathana and SIMEAUNGKHOUN, Mekkhala} }
