Studies on the Physiological Specialization of Cladosporium fulvum Cooke

II. Racial Identification of Isolates Collected from 11 Prefectures in Japan from 1971 to 1973

Abstract

Sixty isolates of Cladosporium fulvum, collected from eleven prefectures in Japan, were identified as race 0 (48 isolates) and race 1 (12 isolates), according to Day's system. Additionally, seven isolates of race 0 and six isolates of race 1 were classified into three pathogenic types on the basis of their pathogenicity to Japanese resistant varieties of tomato, Okitu No.8, Kyoryoku goko and Shiko No.471.
