Genetic comparison of planted and natural Quercus robur stands in Russia

Year: 2020

Type: article

Abstract: Genetic diversity and the optimal genetic composition are essential for the adaptability and adaptation of tree populations. Artificial regeneration of stands might reduce the genetic diversity and increase family structures if the seeds were collected from a limited number of mother trees. We did a genetic inventory in 12 pedunculate oak stands in Russia using a set of 366 nuclear gene markers (361 SNPs, 5 Indels) in order to look for differences in the genetic composition among natural and artificial stands. Our results did not reveal any systematic differences among both types of stands. However, we found two extreme cases of limited genetic diversity and increased proportion of full-sibs and half-sibs in urban man-made stands. The implications for the forestry and gene conservation programs were discussed.
