-Accessions US4808 and US4809 were identified as resistant to the four genetic clades of //X. fragariae// (Maas //et al//., 2002; Hartung //et al//., 2003). Introgression of the trait into commercial quality perennial-type germplasm was initiated by Roach //et al//. (2016). Resistance detected in two wild accessions US4808 and US4809 was found to be highly heritable and controlled by a major locus //FaRXf1// on linkage group 6D (Roach //et al//., 2016). Annotation of the //FaRXf1// region in //F. vesca// 
genome revealed the presence of several resistance-associated genes, including nucleotide-binding leucine-rich
repeat (NB-LRRs), zinc finger and serine/threonine-protein
kinase genes (Roach //et al//., 2016). Allelic diversity at the //FaRXf1// locus is unknown.+
