GBS data of Cornus florida pseudo-F2 population: F2-06-128
DNA was extracted using the QIAcube (Qiagen, Hilden, Germany) with the QIAamp 96 DNA QIAcube HT Kit (Qiagen) following the manufacturer's protocol, except for doubling the RNase (8ul) and adding 2% mass/volume polyvinylpyrrolidone (PVP) to the working solution. Samples were sent for genotype-by-sequencing (GBS) at The University of Wisconsin-Madison Biotechnology Center (Madison, WI, U.S.) with PstI/MspI restriction enzymes. Samples were sequenced on the Illumina NovaSeq X Plus platform.
