TI - Distribution of some viruses affecting faba bean in El-Beheira Governorate and screening of some faba bean cultivars for resistance to the most prevalent one KW - Fava bean KW - Diseases and pests KW - Resistance KW - Bean yellow mosaic virus N1 - Includes reference N2 - Field survey studies carried out during the growing seasons 2000/2001 and 2001/2002 in El-Beheira governorate revealed the presence of Bean yellow mosaic virus (BYMV), Broad bean mottle virus (BBMV), Broad bean true mosaic virus (BBTMV), Broad bean stain virus (BBSV) and Pea seed borne mosaic virus (PsbMV). BYMV was found to be the most prevalent virus, while BBMV was the least one. BYMV was detected in 99 and 98 samples out of 114 and 155 tested samples in the growing seasons 2000/2001 and 2001/2002, respectively. The percentage of mosaic and mottle diseases incidence ranged from 27 to 77% during the two seasons survey. A total of fourteen faba bean cultivars were screened for resistance to infection with BYMV; the most prevalent one using infection percentage, disease index and concentration as a parameters for evaluation under greenhouse conditions. Results showed that all the tested cultivars were highly susceptible to BYMV. Giza 2 cultivar was found to be the highest susceptible and Nobaria 1 cultivar was the least one UR - http://nile.enal.sci.eg/EALE/2008/AAR/1308/1/107.pdf ER -
