This study was carried out during the growing season 2004-2005 at faculty of science-Omar AL-Mokhtar University the purpose of this study was to isolate and identify the pathogenic fungi Carried on seed of collected chickpea cultivars and estimate their pathogenicity Twelve species of fungi (Aspergillus ustus, A.candidus, A.niger, Cladosporium sp., Chaetomium bostrychodes, Fusarium oxysporum, Phomopsis sp., Pencillium frequentans, Pythium ultimum, Thielaviopsis sp., Rhizopus sp., and Rhizoctonia sp.) Were isolated from seed samples Of local and LIC cultivar.Pathogenicity was tested for isolated fungi on their hosts. Results of pathogenicity test for isolated from local chickpea seeds showed Significant differences between seeds sowned in contaminated soils with isolated fungi and soils free from fungi as control, using percentage of pre and post emergence damping off disease index,seedling length, root length and total fresh and dry weight. Results showed that F. oxysporum gave the highest percentage of pre and post emergence death. Results of pathogenicity test for fungi isolated from chickpea seeds(var. LIC) showed significant results when used The previous parameter and showed that Pythium ultimum gave the highest percentage of pre and post emergence death.
