Interpretive Summary:

Technical Abstract: VitisGen is a multiple institute collaborative project funded by the USDA SCRI program, with a long term goal to accelerate grape cultivar improvement by using cutting-edge molecular marker technologies, rigorous centralized facilities to characterize traits, and molecular breeding expertise. The genotyping team of the VitisGen project adopted the genotyping-by-sequencing (GBS) platform, which is a high-throughput and low-cost genotyping platform originally developed for the highly inbred maize and sorghum populations. We will present an overview of the technology, current progress in adapting GBS for marker discovery and map construction in the outcrossing grape populations, and strategies for transitioning from marker discovery to marker application using GBS. We will also discuss the development of QA/QC procedures for large scale cross disciplinary research collaborations.
