Abstract
Pathogenicity and maceration capacity of Erwinia sp. Isolations, obtained from seeds of potato tubers of the variety Spunta with soft rot, was studied under laboratory conditions. Pre weighed healthy tubers of the same variety were inoculated with 200 µL of a 108 ufc/ml bacteria suspension, placed in an incision of 2 cm of depth in the stolon area. In evaluations at 3-, 7and 10-days tubers were washed to eliminate the decayed tissue and weighed again to determine the weight reduction. All isolations studied were pathogen and caused soft rot to the inoculated tubers. The isolations that caused total disintegration of the tubers between 3 and 7 days and made losses between 63.52% and 74.38% were considered more virulent; their prevalence in the studied locate them among the possible causes that motivated soft rot in potato seeds.
