Genomic selection accuracies within and between environments and small breeding groups in white spruce

Summary:

Published in BioMed Central Genomics 15: 1048. https://doi.org/10.1186/1471-2164-15-1048

Genomic selection (GS) may improve selection response over conventional pedigree-based selection if markers capture more detailed information than pedigrees in recently domesticated tree species and/or make it more cost effective. Genomic prediction accuracies using 1748 trees and 6932 SNPs representative of as many distinct gene loci were determined for growth and wood traits in white spruce, within and between environments and breeding groups (BG), each with an effective size of Ne ≈ 20. Marker subsets were also tested.
