Bacterial wilt is the most important disease of potato in Southern Kerman. The results of phenotypical, biochemical, nutritional and pathogenicity tests on 48 strains isolated from wilted potato in Southern Kerman(Jiroft, KaBam, Baft and Bardsir cities) showed that Ralstonia solanacearum is the causal agent of the disease in these areas. All strains of R. solanacearum examined were very similar in all but 25 phenotypic feafures and belonged to race 3, phenotype B of biovar 2 (biotype 2-A). Strains appeared very similar to almost identical in whole-cell protein patterns in SDS-PAGE and also in agar-gel diffusion tests, when a polyclonal antiserum prepared in rabbit against a representative strain was used.
