Abstract

Laboratory and field experiment were conducted at the college of Agriculture, University of Baghdad to investigate the variability in cultural, Morphological characteristic and pathogenicity of the casual of dry root rot, Fusarium solani on sour orange from different regions in Baghdad province. Results indicated the presence of 16 F. solani isolates and the appearance of the fungus at high rates ranged between (93-100) percent in all regions. It might be the dominant fungus in the roots of the sour orange .There were a significant differences between these isolate, Pathogenicity tests of these isolates on cabbage and sour orange seeds indicated that the percentage of germination between (3.3-26.3) % and (30-70) % for cabbage seed and sour orange respectively compared with 96.66 % for the control treatment. Al-Jadriyah isolates considered the most effective and the high pathogenicity where sour orange seed germination did not exceed 38.3% , while it ranged from (48.3-66.6) % for the rest of other isolates .
