A genotype-by-sequencing dataset and identity-by-state matrix of genetic variation in Pinus radiata from 16 counties

Pinus radiata is a commercially important softwood species planted
extensively worldwide, while its native populations remain endangered and
of high conservation concern. This dataset provides genome-wide SNP
genotyping data generated via genotype-by-sequencing (GBS) using
double-digest RAD sequencing (ddRADseq) on needle-derived DNA. Samples
were collected from 16 countries and include both domesticated breeding
material and wild-origin individuals from native populations. The dataset
includes a SNP-by-sample matrix and an identity-by-state (IBS) matrix
describing pairwise genetic similarity among individuals. These data
support applications in population structure analysis, breeding program
design, genetic resource management, and conservation planning for P.
radiata.
