High-density linkage maps and loci for berry color and flower sex in muscadine grape (Vitis rotundifolia).

Linkage maps of muscadine grape generated using genotyping-by-sequencing (GBS) provide insight into genome collinearity between Muscadinia and Euvitis subgenera and genetic control of flower sex and berry color. The muscadine grape, Vitis rotundifolia, is a specialty crop native to the southeastern USA. Muscadine vines can be male, female, or perfect-flowered, and berry color ranges from bronze to black.
