One hundred and thirty one isolates of Rhizoctonia spp. were isolated from faba bean plants showing root rot and stem canker collected from different fields in Delta region of Egypt. Forty six isolates were found to be polynucleate and the remaining isolates were binucleates. According to morphological features of isolates, they were classified into 12 groups. Polynucleate isolates were identified as Rhizoctonia solani (Kühn). The most aggressive isolate of R. solani was identified according to sequences of ITS1-5.8S rDNA-ITS4 and the sequence was compared with Thanatephorus cucumeris (teleomorphic phase) and other R. solani (NCBI GenBank). Sequence and comparison revealed that this isolate is R. solani AG4-HGI. Anastomosis test carried out between molecular identified isolate and 11 randomly chosen isolates resembles all groups of polynucleate R. solani. All tested isolates were completely fused between each other indicating that the prevalent AG of R. solani on faba bean is AG4-HG1.
