Anthracnose, caused by Colletotrichum lindemuthianum (Sacc. and Magnus) Briosi and Cavara is a fungal disease that affects common bean worldwide. Seed yield loses sometimes reach 100% when the seed is infected and environmental conditions favor the disease. Climbing beans in Guatemala represent the main source of protein for the habitants of this region (9.4 kg/person/year). Unfortunately, anthracnose threatens climbing bean production in the region. Six races were found among samples collected in Guatemala Highlands using the standard common bean differential lines. Also, a germplasm collection from ICTA Guatemala was evaluated for resistance to C. lindemuthianum race 73, which is the predominant race in the U.S. Approximately 10% of 369 climbing bean accessions showed no symptoms (score of 1). GWAS results using 78754 SNP markers indicated that genomic regions for resistance to C. lindemuthianum exist in Pv04 and Pv07. / USAID-Legume Innovation Lab / ICTA (Guatemala)
