Abstract
To study Fusarium species associated with potato dry rot during October 2001-April 2002, samples from stored potatoes were collected from Ardabil, Tehran and Hamedan provinces. Decayed segments were cultured on potato dextrose agar. Species were identified based on morphological characters. A total of 208 isolates obtained belonging to Fusarium acuminatum, F. culmorum, F. equiseti, F. lateritium, F. oxysporum, F. sambucinum, F. solani, F. reticulatum and F. verticillioides. This is the first report of F. culmorum and F. reticulatum as the causal agent of potato dry rot in Iran. The prevalence of isolated species in descending order for Ardabil Province was F. equiseti, F. sambucinum, F. oxysporum, F. solani, F. culmorum, F. lateritium and F. verticillioides; for Tehran Province was F. oxysporum, F. solani, F. equiseti, F. sambucinum and F. reticulatum and for Hamadan Province was F. sambucinum, F. acuminatum, F. solani, F. oxysporum, F. equiseti and F. reticulatum. A conidial suspension (1×104 conidia/ml) for each isolate was inoculated on potato tubers. Isolates of F. solani were the most pathogenic while those of F. reticulatum had the lowest pathogenicity. F. sambucinum, F. oxysporum and F. solani were the most pathogenic species in all three provinces, whereas F. equiseti and F. acuminatum, were respectively important in Ardabil and Hamedan Provinces.
