Abstract
Under greenhouse and field conditions all peanut cvs. tested varied ¡n their




susceptibility to infection by damping - off, and peanut root rots, Ismaflia I and R 92




cvs. were the most resistant against infection by damping -off, and peanut root rot




diseases and gave the highest percentage of survived plants, while Giza 5, Giza 4




and Gorgia cvs. were the highly susceptible cultivars to infection by dampingoff and




peanut root rot. Varietal reaction showed that pod rot diseases were common on al




cultivars and the nine cultivars tested differed greatly in their reaction to the diseases,




also no one of these cvs. showed completely resistance to aflatoxin production and




¡nvasion with aflatoxšgenic fungi. Aspergillus flavus was more invasive than




Aspergillus parasiticus and often dominated in peanut seeds than shells. Giza 4,




Gorgia and Giza 5 cvs. were the highest susceptible one to pod rot diseases and




recorded at the same time the highest frequency of aflatoxigenic fungi and content of




aflatoxin. While. R 92 and Ismailia I cvs. appeared high resistance in this respect.
