Abstract

isolation was made from wilted plants of faba bean, lentil, and chickpea; collected from different regions of Egypt. Isolates of F.oxysproum collected from each crop were grouped depending on their habit characters. Four isolates from faba bean representing four groups of isolates, 6 from lentil, and 6 from chickpea were used in this study. Morphological characters, pathogenicity and pathogenic variability of each crop isolates were studied. The results proved that, all isolates from faba bean were F.oxysporum f.sp.fabae, isolates from lentil were F.oxysporum f.sp. Len­tis and isolates from chickpea were F.oxysporum.sp. ciceri. Morover, re­sults showed clear variation among isolates of each crop, hence we roughly subdivided F.oxysporum f.sp. fabae into 3 types and F.oxysporum f.sp. Lentis into 4 types. F.oxysporum fan. ciceri showed clear variation among the tested isolates in their habit characters.
