Among the several biotic limiting factors for sunflower production, Alternaria leaf blight is a potential destructive foliar disease of sunflower in India and elsewhere causing significant yield losses during rainy season. Three CMS lines were crossed with fourteen testers in an L x T mating design and derived forty two experimental hybrids which were evaluated under natural epiphytotic conditions.
