Targeted Genotyping by Sequencing (GBS) is a robust and cost-effective method for marker-assisted breeding and selection. Targeted GBS provides a scalable workflow, allowing for thousands of markers to be genotyped in up to thousands of samples per day. As GBS use expands, demand increases for higher throughput, faster turnaround times, and increased multiplexing capability.
To achieve higher throughput with less material and greater ease of use, we propose a new library prep workflow using partial combinatorial dual barcodes for use with the Ion GeneStudio™ S5 System that not only increases available barcodes, but also achieves complete, normalized libraries for up to 3072 samples in less than a day. Additionally, we propose an analysis workflow optimized for more than 6000 samples to be sequenced and genotyped in less than 24 hours using a single Ion GeneStudio™ S5 System. These optimizations enable completion of genotyping of >30,000 samples within a 5-day week. Here we report early testing results showing high quality results achieved using this novel workflow and analysis pipeline.
