Abstract
Powdery mildew is a devastating disease in sesame during rabi season, causing considerable yield loss. Utilisation of host plant resistance mechanism is ideal disease management strategy and knowledge of inheritance of tolerance/resistance to powdery mildew will be quite helpful in formulating breeding program. In the present investigation, 30 genotypes were screened against powdery mildew, of which 18 showed susceptible and 12 tolerant reactions. None of the genotype recorded immune response. Study on inheritance of tolerance to powdery mildew revealed that susceptibility was dominant over tolerance and is controlled by two independent recessive genes with complementary epistasis.
