600 grain samples collected from wheat fields in Hail area at the northern part of Saudi Arabia was used for this study. Isolation and identification of seed-borne fungi were conducted according to standard tests described by the International Seed Testing Association (ISTA) using YGCA medium. A total of 505 of external mycoflora and 705 of internal mycoflora  were grouped into five fungal genera namely, Aspergillus ; Alternaria  ; Penillium ; Fusarium and Ulocladium spp. were isolated. Comparsion  between  frequencies and relative densities of external and internal  mycoflora was carried out among the species of the predominant genera. Aspergillus flavus and A. niger reaveled high Fr. and RD of external mycoflora (A. flavus Fr.67.5 - 48.2% , RD. 44.3 - 38.3% and  A. niger Fr. 50.8 - 50.8% and RD. 41.4-36.4 respectively). All the species of Ulocladium and Alternaria were predominant as internal mycoflora except Alternaria  alternata . The most predominant species of Ulocladium and Alternaria were U. atrium (Fr 84.2% -75.8 and RD 88.4%-76.6 as internal – external mycoflora respectively)  and Alternaria alternate (Fr 75.5% - 45.2% and RD. 37.2 - 68.8  as external –internal mycoflora respectively).
