Rare and private alleles as a measure of gene pool richness in Scots pine planting material

In forestry management, artificially produced planting material is mainly used for renewal the tree population. Seedlings are cultivated in two systems: in the ground (the bare−root seedlings) and in controlled conditions (container seedlings). The aim of the study was to analyse the microsatellite markers of nuclear and chloroplast DNA, in terms of the number and frequency of rare, private, low frequency and common alleles in the planting material of Scots pine. The rare alleles included alleles occurring with less than 1% in analyzed group of seedlings and low frequency alleles occurred with a frequency of less than 25%. The private alleles were detected only in one group of seedlings. Genetic pools of seedlings from traditional (soil) and container production were compared. Planting material came from nurseries in the Olsztynek (N Poland) and the Oleszyce (S Poland) forest district. With the similar number of observed nDNA and cpDNA alleles in both analyzed locations, a higher number of rare, low frequency and private alleles was found within container seedlings. Most private alleles were a rare allele. Rare and private alleles are supposed to be responsible for adaptation to changing climatic conditions and a stressful environment. It seems reasonable to continue research on the meaning of rare and private alleles under conditions of strong selective pressure.
