The relationship between the appearances of brown color in the intercotyledonary plane of pistachio nuts is confirmed earlier as a good indicator of high-aflatoxin contaminations. This is used in the present study to investigate the distribution of highly contaminated nuts among three pistachio cultivars and different hull types (i.e., intact green hull, growth split and early split nuts). All individual pistachios were classified based on BGYF presence on shell before the examination of the intercotyledonary area for brown color. The results indicate that the early split pistachios had highest BGYF incidence among all cultivars. There was a significant difference between cultivars, as well. The incidence of brown kernel was significantly different among cultivars and hull types. It is concluded that the BGYF sorting could be used in all studied cultivars to remove possible contaminated nuts. A significant difference between cultivars in share of brown kernels indicates that there is an inherent genetic potential in pistachio for control of aflatoxigenic fungi.
