A comparative study of yellow-anthered and red-anthered forms of Scots pine, growing in hydrothermally contrasting bog and upland ecotopes, was performed by karyological traits and nuclear DNA content. Some differences were revealed between yellow-anthered and red-anthered forms of pine as components of intraspecific diversity in the frequency of occurrence of violations in the number of chromosomes, chromosome sizes (total length of diploid set, absolute and relative lengths), the centromeric index, the localization of secondary constrictions in chromosomes, and the amount of DNA.
