Genotyping by sequencing data from North American Picea and Larix individuals
Here we present genotyping by sequencing (GBS) data from 382 conifer individuals (P. mariana (Mill.) B.S.P., Picea glauca (Moench) Voss, and Larix laricina (Du Roi) K. Koch) from the Arctic-Subarctic forest–tundra transition zone in north-western Canada and Alaska (~ 55–70°N, 170–70°W).
