With 4 figures and 3 tables Abstract Many volatile compounds have been shown to influence the flavour of strawberry (Fragaria spp.) fruit. A published study demonstrated that linalool, a critical flavour compound, is produced in cultivated F. × ananassa varieties owing to a truncated form of the NEROLIDOL SYNTHASE (NES) enzyme. The corresponding allele (FaNES1) features a 5′‐deletion that is detectable by PCR. Herein, we tested a broad set of strawberry genotypes to understand the origin of the allele and to identify materials that may be preferred candidates for molecular breeding. The results indicate that the FaNES1 allele (linalool+) is not present in any diploid, tetraploid or hexaploid accession tested. It is present in 112 F. × ananassa cultivars examined. The FaNES1 allele is present in all but three of 46 wild F. virginiana and F. chiloensis genotypes. Two of these three lines continue to produce linalool despite the absence of the allele. This survey suggests that the FaNES1 allele possibly arose following octoploidization and that linalool possibly is an important factor in strawberry biology, aside from its role in anthrocentric fruit quality attributes.

“…These findings also reinforce the utility of vetting potential breeding decisions with molecular markers. The supercore collection of octoploid genotypes has been assembled as representing the diversity of both wild octoploid species and also representing desirable breeding accessions based on many traits (Hancock et al. 2001).…”

“…Based on our own evaluations and previous published reports, we also assembled an elite group of nine North American F. chiloensis genotypes that possessed horticulturally important traits and represented a considerable portion of the geographical range of this species in North America (Hancock et al 2001a(Hancock et al , 2005. We crossed the elite groups of F. chiloensis and F. virginiana with one another and evaluated the hybrid progeny.…”

“…Herein, we describe the variation for several important horticultural traits in these reconstructed F. £ananassa populations including winter injury, photoperiod sensitivity, Xowering date, fruit size, female fertility, and disease resistance and relate these Wndings to our previous evaluations of crosses of the F. virginiana parents with F. £ananassa cultivars . (Hancock et al 2001a). Pigeon Point is female, FRA 0319, FRA 0596, and FRA 0688 have large fruit (particularly FRA 0688), are female, and are probably mildew resistant.…”
