Previously collection specifically for wild relatives of azuki bean was conducted by Tomooka (1997) in the area of Fukuoka (福岡), Kumamoto (熊本) and Saga (佐賀) prefectures. During that trip 4 populations of wild azuki were collected. The trip reported here continues the collecting on Kyushu (九州) of the previous mission report of this volume (Tomooka et al., 1999b). The main observations during the trip were that, in less densely populated areas, wild Vigna angularis is sporadically found. Weedy Vigna was found in only one place an unusual shaded habitat. Most of the plants of this weedy population were beneath young coniferous trees. It is possible that the habitat had once been an azuki field and was subsequently planted with trees perhaps about 10 years previously. One seemingly small complex population was found with wild plants and very large plants with very big leaves which appeared to be weedy Vigna. The large size of the plant similar to collection made in Tottori (鳥取) in 1997 (Tomooka et al., 1999a) may have been due to its shady location. Wild soybean (Glycine soja) populations were commonly found throughout the journey. In addition escaped cowpea (Vigna unguiculata) was collected at widely scattered locations in Kyushu (九州). A total of 43 bulk samples were collected, in addition 148 single plant samples were collected from 11 populations of wild or weedy V angularis, and 5 populations of Glycine soja (Table below). For most populations both root nodules and herbarium specimens were obtained.九州では、1996年に福岡、熊本、佐賀において野生アズキを中心とした探索を行い、野生アズキ4集団を収集した (友岡、1997)。本探索は、本報告書のひとつ前の探索報告 (友岡ら、1999a) の隊に続いて福岡から出発し、長崎半島を除く九州を一周したものである。雑草アズキは1集団見つかったが、この生息地はこれまで雑草アズキが良くみられた生育環境とは異なり、若い針薬樹林の下の低日照環境であった。ここは、以前アズキ畑であった場所に針葉樹が10年ほど前に植林された可能性も考えられる。一つの野生アズキ集団では、雑草アズキかと思われる大きな葉を持った大型の個体が混生していたが、これには生息場所の低照度も影響しているかもしれない。野生ダイズは、九州の各地で頻繁にみられた。また、九州ではササゲのエスケープ集団が多くの場所で形成されていることが確認された。本探索では、43集団を調査し種子の収集を行った。11地点の野生・雑草アズキ集団および5地点の野生ダイズ集団からは個体別に種子の収集を行った。また、ほとんどの集団から、根粒を収集し植物体の標本を作成した
