Exploring the genetic basis of anthracnose resistance in Ethiopian sorghum through a genome-wide association study.

ABSTRACT:

Background

Sorghum anthracnose is a major disease that hampers the productivity of the crop globally. The disease is caused by the hemibiotrophic fungal pathogen Colletotrichum sublineola. The identification of anthracnose-resistant sorghum genotypes, defining resistance loci and the underlying genes, and their introgression into adapted cultivars are crucial for enhancing productivity. In this study, we conducted field experiments on 358 diverse accessions of Ethiopian sorghum. Quantitative resistance to anthracnose was evaluated at locations characterized by a heavy natural infestation that is suitable for disease resistance screening.

Results

The field-based screening identified 53 accessions that were resistant across locations, while 213 accessions exhibited variable re
