Genetic structure of the populations of pinus sylvestris l. and pinus cretacea kalen. and their taxonomic relationships



Genetic structure of the populations of pinus sylvestris l. and pinus cretacea kalen. and their taxonomic relationships



Doklady Akademii Nauk SSSR 319(5): 1230-1234



Isoenzymes were used as the most accurate markers to describe the population and genetic structure of P. sylvestris and P. cretacea, as well as to determine the level of differentiation between these species and to establish their taxonomic status. Pine tree endosperms were analyzed to determine tree genotypes. A diagram that demonstrates the electrophoretic localization of 68 allele variants of 21 loci is presented. It was found that P. cretacea growing on ancient calcareous deposits is a form of P. sylvestris adapted to specific growing conditions. The genetic data obtained in the study show that the most correct taxonomic name of P. cretacea should be P. sylvestris var. cretacea.
