Abstract

An investigation was carried out with fifty sesame genotypes to identify source of resistance to powdery mildew and macrophomina stem/root rot diseases during late kharif 2022 at RARS, Jagtial under protected conditions. Among the genotypes screened, four genotypes JCS 4047, JCS 4026, JCS 3880 and GT 10 were found resistant to powdery mildew. The powdery mildew PDI was ranged from 25.1%-73.3%. Based on the PDI score, fifty genotypes were classified into Resistant (4), moderately resistant (27) and Susceptible (19) categories. From fifty genotypes, JCS 4047 showed highly resistant reaction and EC 182833 showed highly susceptible reaction to powdery mildew. The macrophomina stem/root rot incidence was ranged from 65%-100%. FFAT 04 shown the lowest root rot incidence (65%) among fifty genotypes screened. None of the genotypes found to be immune. Identified resistant genotypes can be utilized as parents in breeding programme for development of resistant varieties.
