Opis:: Four cpDNA regions were analyzed with the use of PCR-RFLP technique and nucleotide sequences of two mtDNA regions were characterized in order to find P. sylvestris and P. mugo species specific markers useful for studies of the species hybridization. The difference in the restriction fragment patterns of trnV-rbcL region after digestion with MvaI endonuclease was detected. The analyses of the species representatives from various geographic regions revealed that the observed polymorphism is species specific. No differences have been disclosed in the analyzed trnS-trnT, trnK1-trnK2, trnC-trnD cpDNA regions. The P. sylvestris and P.mugo mtDNA sequences of orf25 and coxI regions proved to be identical.

Opis:: The aims of this study were 1) to determine the variability in the flowering phenology of Scots pine (Pinus sylvestris L.) clones in a seed orchard and 2) to compare the genetic structure and genetic markers (13 isozyme loci and 5 chloroplast and 3 nuclear DNA microsatellite loci) among groups of clones that are differentiated by flowering phenology. Using the timing of male inflorescence development, 57 plus trees represented by their clones in a seed orchard were classified into three phenological groups: early-, intermediate-, and late-flowering. The microsatellites showed no significant differences in the genetic structure of the analyzed phenological groups. However, the frequency of allele 2 at the shikimate dehydrogenase A locus (ShDH A 2) differed significantly between the groups of early- and late-flowering trees and between the groups of intermediate- and late-flowering trees. In addition, a significant difference in the frequencies of the genotype ShDH A 11 was observed between the intermediate- and late-flowering groups. Nei’s genetic distance indicated that the late-flowering group was the most genetically distant among the phenological groups. These results suggest that the ShDH A locus might be considered as isoenzymatic marker that differentiates these flowering groups of Scots pine clones. At several isozyme and DNA loci, the presence of private alleles in each group of pines was observed. However, these alleles cannot serve as markers of Scots pine flowering time because of their low frequencies.
