Abstract
The effect of inoculum concentration on the efficiency of a laboratory screening technique using whole plants, for determining the resistance to Cercospora arachidicola [Mycosphaerella arachidis] in groundnuts was studied using 5 cultivars with varying levels of resistance. Disease symptoms appeared on the tagged leaves of all genotypes within 6 days after inoculation. There were significant differences between the conidial concentrations for most of the disease components studied. In general, number of lesions, percentage leaf area damaged and percentage defoliation were higher with the highest conidial concentration (1000 conidia/millilitre). The number of conidia per lesion was significantly higher in susceptible genotypes than in resistant genotypes.
