Due to the symptoms starting belatedly, this disease can frequently be detected only when fruits arrive at the importer country, thus generating economic loss for the exportation of the fruit. This study was developed with the aim to investigate which Fusarium species cause peduncular rot in melon and to evaluate if there are differences in aggressiveness and development of symptoms. Species were identified through phylogenetic analysis of two loci and morphological markers. The 28 isolates obtained from diseased melon fruits of different commercial cultivars were identified as Fusarium falciforme (FSSC), F. sulawesiense, F. pernambucanum (FIESC) and F. kalimantanense (FOSC). Three isolates belong to a new phylogenetic lineage within the Fusarium fujikuroi species complex (FFSC). All isolates were tested for pathogenicity, and two days after inoculation, first symptoms of rot in Canary melon were observed. Isolates of F. falciforme and F. sulawesiense showed to be more aggressiveness. Our results extend information on Fusarium species that cause peduncular rot in melon and support the development of management strategies, once there is currently no efficient control for this disease. To our knowledge, this is the first report of occurrence of species from the FSSC, FOSC and FFSC in muskmelon fruits.} }
