Resistance to Aspergillus flavus in peanut was evaluated through two consecutive experiments (1) in the laboratory by inoculated seeds of 16 cultivars and (2) in the field by inoculated the pathogen into the soil during plant growth. Many cultivars which were susceptible to the fungi in experiment 1, exhibited the resistance in experiment 2. This indicated in consequence, that resistance performed in experiment 1 was due mainly to the condition and composition of seeds which in contrast, the resistance performed in experiment 2 was the action of the resistant gene expressing during physiological processes of plant growth. It therefore, can be concluded that resistance to A. flavus in peanut is due partly to the existed resistant gene and partly to the environment. The correlation between percentages of infected seeds in both experiments was also found to be statistically nonsignificance indicating that niether laboratory test nor field condition test can represent each other. Nevertheless, testing for the resistance needs to be conducted under both conditions.
