Abstract
Forty isolates of Botrytis spp. collected from faba bean growing governorates of Northern and Midde Egypt were compared for their mor­phological and physiological characters, as well as for their virulence and aggressiveness on four faba bean cultivars, namely Giza 402, Giza 3 Giza 461 and Giza 716. Bowls spp. isolates showed differences in growth rate, spore production, number and size of sclerotia, and aggressiveness on the 4 different faba bean cultivars. B. fabae isolates which showed the least amount of growth, spore production, and the highest number of small sclerotia were the most vir­ulent on the 4 tested cultivars, while acinerea isolates which were the fastest in growth rate, the highest in spore production and the least in number of large sclerotia were the least virulent on such tested culti­vars. Moreover, results showed differences in virulence among isolates of B.fabae themselves, where isolates obtained from Nubaria were more virulent than those obtained from other governorates.
