Sesame (Sesamum indicum L.) is one of the most ancient oilseed crop and rich source of oil, protein, calcium as well as phosphorus, which is cultivated throughout Pakistan. An investigation was conducted during the 2010, in kharif season to identify the resistant sources among four sesame varieties against Alternaria leaf spot disease (Alternaria sesami (Kawamura) Mohanty & Behera. The plants of sesame varieties were evaluated on 0-5 scale against A. sesami in pots and under field conditions for disease reaction. In pot, as well as in field experiments, none of the sesame variety was completely immune. The sesame variety S-122 appeared to be highly resistant and placed in "1" reaction category. Latifi and S-131, placed under category "3", they appeared as moderately susceptible. Variety S-117, placed in "5" reaction category, appeared as highly susceptible sesame variety against sesame leaf spot pathogen.
