High-density linkage map and QTL analyses for fruit quality traits in the wild blueberry relative Vaccinium stamineum.

ABSTRACT: The wild blueberry relative Vaccinium stamineum offers a rich source of diversity for expanding the genetic pool of cultivated blueberries, and it has also potential for breeding as a crop on its own. Understanding the genetic architecture of fruit quality traits in this wild species can facilitate and speed up future breeding efforts for introgression and de novo domestication. Therefore, in this study, we developed a biparental population of 147 progenies from V. stamineum, which were phenotyped and genotyped for quantitative trait loci (QTL) mapping. Phenotypic data for acidity [total titratable acidity {TTA} and pH] and sweetness (soluble solids content) were collected over 3 yr. Genotypic data were obtained through targeted sequencing using 6,000 probes developed for blueberry. A link
