摘要: The first genetic map of cranberry (Vaccinium macrocarpon) has been constructed, comprising 14 linkage groups totaling 879.9 cM with an estimated coverage 82.2 %. This map, based on four mapping populations segregating for field fruit-rot resistance, contains 136 distinct loci. Mapped markers include blueberry-derived simple sequence repeat (SSR) and cranberry-derived sequence-characterized amplified region previously used fingerprinting cultivars. In addition, SSR were developed near sequences resembling genes involved in flavonoid biosynthesis or defense against necrotrophic pathogens, conserved orthologous set (COS) sequences. SSRs from next-generation genomic assemblies; thus, the positions these provide information about location scaffold which they derived. use COS other functional sequences, plus 33 blueberry, facilitates comparisons this maps plant species. Regions identified that showed conservation synteny Vitis vinifera Arabidopsis thaliana. Positioned are quantitative trait loci (QTL) resistance (FFRR), fruit weight, titratable acidity, sound yield (SFY). SFY QTL is adjacent to one weight may reflect pleiotropy. Two FFRR regions grape span gene markers, third spans a biosynthetic gene.
