Abstract

In order to identify FUSARIUM species associated with ROOT AND CROWN ROT of POTATO, several Field in different region of GORGAN were sampled during growing season (2003-2004). For isolation of fungi, some parts of diseased tissue (root and crown) were surface sterilized with sodium hypochlorite 5% and washed three times with sterile distilled water, and then placed on acidified POTATO dextrose agar. From diseased tissue 35 isolates of FUSARIUM spp. were isolated and purified by single spore. By valid books of FUSARIUM species identification of five species: FUSARIUM oxysporum, F. equiseti, F. moniliforme, F. solani and F croockwellnse were identified, with 22.85, 8.57, 14.28, 42.5, 11.42 frequency percentages respectively. FUSARIUM solani was the most abundant one. Pathogenicity test was performed by inoculation of spore suspension (2x106) on root and crown of 25 days old plants of marfona POTATO cultivar. The result showed that pathogenesis of all fungal isolates of F.solani except oneisolates and all isolates of F.oxysporum, F.moniliforme, Fcroockwellnse and F.equiseti performed root necrosis in mainroot and their branched. In relation to those species of F.oxysporum and F.solani colourchanges of vascular tissue was observed after inoculation on crown part of POTATO. This study was the first report of FUSARIUM on POTATO in GORGAN area.
