Twenty-one (21) diverse horsegram accessions collected from various parts of Andhra Pradesh state were screened in greenhouse along with four check varieties against Colletotrichum dematium, causal agent of anthracnose disease. Based on Per cent disease index (PDI), one accession, IC470275 was identified as immune and the remaining accessions were either moderately resistant or susceptible. Grid maps generated using DIVA-GIS indicated the areas with highest Shannon diversity index for PDI and highest coefficient of variation recorded for horsegram accessions collected from Anantapur district of Andhra Pradesh. The results also indicated that diverse accessions for reaction against C. dematium can be sourced from Anantapur district of Andhra Pradesh.
