ASHS 2024 Conference

Numerous QTL and GWAS studies have been conducted on various species of Prunus, but there is limited knowledge on the overall genetic architecture regulating fruit quality traits among these species. As part of a 2022-funded SCRI- project to advance database resources for specialty crop research, efforts are directed towards collecting and curating all types of big data in the Genome Database for Rosaceae (www.rosaceae.org). We conducted an extensive literature review on over 120 QTL and GWAS studies on Prunus traits to extend the existing data in GDR. We aligned the traits to the peach genome to compare important traits in various Prunus species. The consensus map showing QTL hotspots will be accessible using various tools in GDR. Implications of the newly created resources and tools in GDR for breeding will be discussed.
