Genotype data of 970 Pedunculate oak trees (Quercus robur L.) in Russia and neighbouring countries at 385 gene loci covering the nuclear and organelle genome

The data set is the result of genetic inventory on 970 Pedunculate oak trees from 97 locations in Russia, Belarus, Ukraine and Latvia representing the eastern part of the natural species range. The data set includes the sample IDs, geographic coordinates of each sampled tree (longitude and latitude in decimal degrees) and the genotype data. All samples were screened with a set of 385 gene markers covering the nuclear (n=364) and the organelle genomes (chloroplast: n=14, mitochondria: n=7) by use of a genotyping by sequencing approach. With exception of three INDELs (Insert and Deletion mutations) all gene markers are SNPs (Single nucleotide Polymorphism).

Methods
At each location ten individual trees were collected. The majority of the samples (85 locations) were collected in natural forest stands and in artificial regenerated stands (7 locations). We set a minimum diameter of 20 cm at breast height and trees separated by a minimum of 50m to reduce the probability to collect related trees. For five locations the material has been collected in a provenance trial which was created in the USSR under the supervision of A. M. Shutyaev on the territory of the Krapivensky forest enterprise-college by employees of the Research Institute of Forest Genetics and Breeding in 1976-1977.
