Charcoal rot caused by Macrophomina phaseolina, is a destructive disease of sesame crop cultivated in Egypt. Eighty six sesame genotypes (Sesamum indicum L.) were used for evaluating disease resistance, in two successive summer seasons 2017 and 2018, in the field. Results obtained showed that highly significant variations were found between sesame genotypes tested in both seasons for disease infection percentage (DI %) and seed yield (SY). In

Sesame is one of the important oil crops in Egypt. It can be infected by fungus Fusarium oxysporum f.sp. sesami which causing wilt disease. Among totally 6 isolates of Fusarium spp. isolated from diseased sesame plants, only isolates of F. oxysporum were found to be significantly pathogenic on sesame Giza-32 cultivar and showed the same ideal wilt symptoms. The objective of this investigation was aimed to; screened 86 sesame genotypes for wilt resistance during summer seasons of 2016 and 2017 under artificial infestation and field conditions with isolate FO2. In first season, a significant differences between genotypes under study in trait of disease infection %. Ten lines were resistance i.
