A diverse strawberry family (FVC11) was created by intercrossing elite native clones of the progenitor species of F . ×  ananassa Duchesne in Lamarck [ F . virginiana Miller ×  F . chiloensis (L.) Miller]. The impressive performance of FVC11 led us to identify a core subset within the family for conservation and breeding purposes. Cluster procedures were conducted on the phenotypic data of 16 traits and 29,251 SNP data generated using the genome wide SNP array, Affymetrix Axiom IStraw90 TW . To select a core group, the best performing individuals were identified in each of the major clades shown in the phenographs derived from the genotypic and phenotypic data. A subgroup of 10 individuals was selected that represents most of the genetic diversity in FVC11.
