Comparison of Cephalosporium gregatum Isolates from Adzuki Bean in Japan and from Soybean in U.S.A.

Abstract

A Japanese isolate (A 10) of Cephalosporium gregatum from diseased adzuki bean stem in Hokkaido, Japan and an Iowa isolate (No. 2) from soybean stem in Iowa, U.S.A. were compared in their cultural and morphological characteristics and Gregatins productivities. The cultural and morphological characteristics of both isolates were almost the same and the growth rates at different temperatures and Gregatins productivities were also similar.
