Description Susceptibility to several biotic constraints, including fungal and viral diseases, is one of the major reasons for low productivity in peanut. This situation is common in several developing countries in Asia and Africa, where resource poor farmers cannot afford expensive chemical pesticides for disease management. With an objective to identify sources of multiple disease resistance in peanut, ICRISAT’s peanut mini core collection (10% of core or 1% of entire collection) consisting 184 accessions was evaluated independently for two important fungal foliar diseases such as late leaf spot (LLS) and rust under field conditions during 2012 rainy season. The same set was evaluated for peanut bud necrosis disease (PBND) under late planting in the field during 2012 rainy season. Results indicated that 8 accessions showed less than 1% PBND incidence, and two accessions (ICG 2019, ICG 13858) were completely immune, compared to the average disease incidence of 25% in the trial and 40% in the susceptible control. In the rust screening trial, 3 accessions (ICG 6022, ICG 11088 and ICG 11426) were highly resistant (
