Abstract

For detection and identification of the causal agents of potato blackleg in Isfahan, the potato fields were surveyed during 2003-2004 growing seasons. Fifty four strains of PECTOBACTERIUM and DICKEYA were isolated from the diseased stems and tubers. According to their biochemical and physiological test results, 43 isolates were identified as D. chrysanthemi. The remaining 11 isolates were placed in the second group which were identical with P. carotovorum subsp. carotovorum in biochemical characteristics. None of the isolates appeared to be P. atrosepticum. The results were confirmed by polymerase chain reaction technique using the recommended specific primer sets. Use of G1/L1 primer pair made it possible to detect Pa, Pcc and Dch in one PCR reaction. By using this primer set, the ITS regions of the bacteria were amplified. On the basis of the banding patterns obtained with G1/L1 the isolates were placed in three groups. The first group of ITS- PCR comprised only the standard isolate Eca SCRI1043. Isolates which were identified as Pcc by biochemical tests were placed in the second group and the third group included isolates that were identified as Dch on the basis of their biochemical and physiological characteristics. Results of the present study indicate that Pcc and Dch are the predominant causal agents of potato blackleg and soft rot in Isfahan.
