Symposium--Using Genotypic Data to Strategically Develop Core Collections, Mini-Cores, and Trait-Specific Subsets

Oral Session

C08 Plant Genetic Resources

Addresses the use of high-throughput genotyping to narrow large collections of accessions down to a manageable number that can then be evaluated by breeders. The goal is to develop core collections, mini-cores, and subsets for specific traits through large-scale genotyping to select accessions for more rigorous and expensive phenotyping. How do genomics-assisted phenotype predictions compare with those that rely on GRIN passport data alone?
