The present experiment was performed to identify, and compare natural mycoflora associated with barley seeds among these locations, also to evaluate sodium hypochlorite’s application, as seed disinfectants against fungal contaminators. Barley seeds were surface disinfected with a 4% sodium hypochlorite for two minutes or washed only with deionized water (control) before plating on potato dextrose agar (PDA) medium. The following parameters were recorded and calculated: seed survival (G %), fungal frequency (F), isolation frequency (IF) and fungal relative abundance (RD). Four fungal species were identified as <em>Aspergillus niger </em>van Tiegh<em>, A</em>. <em>flavus </em>Link (ascomycetes)<em>, Rhizopus stolonifera</em> (Ehrenb. :Fr.) Vuill (zygomycetes)<em>, </em>and<em> Bipolaris australiensis </em>(Bugnicourt) (ascomycetes)<em>. </em>The most predominant recovered species was <em>A</em>.<em> niger</em> followed by <em>B</em>. <em>australiensis</em>, <em>R</em>.<em> stolonifera</em>, and <em>A</em>. <em>flavus</em>, (18.5%), (9.67%) (2.84%), (4.65%), respectively. Results also showed Sultan had the highest seed germination, followed by Almerj and Gerdina, 64.5 %, 44.5%, and 20.5 %, respectively. Moreover, seed’s pretreatment with sodium hypochlorite and seed’s origin had no significant effect on frequency and relative abundance of fungi.</p> ER -
