Efficiency of Using Permanent Seed Sources for Conservation of Genetic Pool of Scots Pine (Pinus sylvestris L.) in Belarus

Abstract

On the basis of electrophoretic isoenzyme, analysis of permanent seed sources of Scots pine from Belarus is conducted. Research revealed that almost all of the analyzed plus stands, genetic reserves, seed orchards of the I order provenance and 71.5 % of seed orchards of the II order support maintenance of the level of average heterozygosity characteristic of Scots pine in Belarus. It is shown that in the plantation and population, seed from permanent seed sources can ensure the conservation of the species gene pool at higher productivity than created forest plantations.
