Resistance Components and Temperature Effects on Epidemiology of Cercospora Arachidicola Hori on Peanuts
Abstract
Different techniques have been used to evaluate peanut resistance to Cercospora leafspot. Using solely the number of lesions produced per leaflet, or the number of conidia produced per mm2 of necrotic lesion, or lesions size as a measurement for resistance to early leafspot has major disadvantages. The purpose of this study is to evaluate the sporulating potential per leaflet, as a measure of resistance. The factors or components determining the sporulating potential were determined using the detached leaf culture technique. The effect of temperature epidemiological implications on sporulation are also discussed.
