Genome-wide association studies for inflorescence type and remontancy in Hydrangea macrophylla

Inflorescence type and remontancy are two valuable traits in bigleaf hydrangea ( Hydrangea macrophylla L.) and both are recessively inherited. Molecular marker-assisted selection (MAS) can greatly reduce the time necessary to breed cultivars with desired traits. In this study, a genome-wide association study (GWAS) using 5803 single-nucleotide polymorphisms (SNPs) was performed using a panel of 82 bigleaf hydrangea cultivars. One SNP locus (...
