Abstract

Three foliar pathogens, early (Cercospora arachidicola [Mycosphaerella arachidis]) and late (Cercosporidium personatum [M. berkeleyi]) leaf spots and rust (Puccinia arachidis) are a major constraint to groundnut production in West Africa, although their severities vary from location to location. A total of 424 germplasm lines was screened for resistance to these pathogens in Niger and Burkina Faso and resistant lines were identified. Some sources of resistance to early leaf spot reported in India showed variable reactions in West Africa. Differential reactions to early leaf spot at different locations indicated that there may be physiological races of the pathogen. Sources of resistance to late leaf spot and rust selected at the ICRISAT Centre (India) were also resistant in West Africa. Multiple disease resistance was evident in lines ICG 1707, ICG 6330 and USA 63.
