Genetic Evaluation of Two-Year Height of Scotch Pine Seedlings

This paper reports the results of genetic analyses of full- and half-sib Scotch pine (Pinus sylvestris L.) seedlings produced from intra- and inter-racial matings. The objectives of the study were to answer the following questions: (1) What is the heritability of 2-year height growth of progeny grown under nursery conditions; (2) How much within-plot variability is there among the different mating types; (3) Are family variance components high enough to make nursery selection effective?
