QTL detection and genomic prediction for resistance to anthracnose in alfalfa (Medicago sativa).

ABSTRACT: Forage production, persistence, and associated ecosystem services provided by the major forage legume, alfalfa (Medicago sativa), may be affected by disease susceptibility. Resistance to anthracnose, caused by Colletotrichum trifolii, has been described as an oligogenic trait, but the precise location of resistance genes on the alfalfa genome is not known. Therefore, we phenotyped a set of 417 alfalfa accessions for anthracnose resistance as the frequency of resistant plants. With available genotyping by sequencing data for 380 accessions from this collection, we performed quantitative trait locus (QTL) detection by genome-wide association study (GWAS) and genomic prediction using a validation set of 97 accessions randomly selected. A wide range of variation for anthracnose resistance was
