The role of tree breeding in reforestation

This article focuses on the creation of seed sources for forest planting or seeding with a special focus on clonal seed orchards supporting planting Norway spruce and Scots pine in Sweden. Supporting long-term breeding and low input breeding is discussed. The focus is not on clonal forestry, although this is discussed. Natural regeneration is not dealt with and provenance choice only briefly. It is not a manual or literature review and focus on my own evaluations, but more detailed reviews can be found in the literature cited. It is intended to contribute some familiarity with many of the relevant genetic aspects on forest plantations
