- Abstract
In order to explore the pathogenicity variation of Sclerotium rolfsii affecting peanut, 39 strains collected from different geographical locations were tested on peanut plants (cut stems and branches, and detached leaves). The results showed that all the S. rolfsii strains were pathogenic on peanut plants, but they displayed a significant difference in disease index. Their disease indices in fields were significantly correlated with those of cut stems, branches and detached leaves tested in greenhouse. The strains within the same MCGs (mycelial compatibility groups) exhibited pathogenicity variation both in field and in greenhouse. The revealed variation of pathogenicity of S. rolfsii could provide theoretical and technical basis for management of peanut stem rot disease and cultivar distribution.
