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.
