作物近縁野生種の収集と調査, 1997 : 4. 茨城・栃木・千葉県におけるアズキおよびダイズ近縁野生種

To study intra-population variation two wild azuki bean (Vigna angularis var. nipponensis) collection sites found last year in Tochigi (Site No. 34) and Ibaraki (Site No. 10) prefectures were revisited on 6^ November and individual sampling conducted. At the collection site 34, variation in seed color and pod color was the same as observed the previous year. Another trip was made to find growing sites and to collect germplasm of wild azuki and wild soybean (Glycine soja) in Chiba prefecture from 11^ to 12^ November. A total of 8 samples was collected consisting of 5 samples of wild soybean, 2 samples of wild azuki bean, and 1 sample of wild and weedy azuki complex population. It was noticed that most of the pods had shattered in the middle of November in the Kanto district of Honshu, Japan
