Journal of General Plant Pathology Aims and scope Submit manuscript

A total of 45 single uredinial isolates of Phakopsora pachyrhizi were collected from rust-infected soybean and wild host plants (Pueraria lobata and G. soja ) at different localities in central and southwestern Japan. Eighteen pathogenic races were identified using a set of differential varieties composed of nine cultivars of soybean and two accession lines of G. soja. Nine and 11 races were found on soybean and wild host plants, respectively. Two races were common to soybean and wild host plants.
