Abstract
The sporulation of C. arachidicola [Mycosphaerella arachidis] on groundnut is defined as the number of conidia produced/infected leaflet after 96 h incubation at 25 plus or minus 1 deg C under continuous light (800 lux) and 100% RH. A detached-leaf culture technique was used to determine sporulation on leaflets of 9 groundnut genotypes. Genotypes that did not differ in numbers of lesions/leaflet, and numbers of conidia/mm2 of lesion were significantly different in number of conidia/leaflet. No conidia were recovered from some genotypes even after prolonged incubation of infected leaflets. There was a significant linear correlation between necrotic area and lesions/leaflet on Comet, PI 109839, Florunner and Tamnut 74. No difference in percent defoliation was observed among genotypes.
