Polymorphism of protein markers of Serbian spruce seeds obtained by cross pollination and self-pollination

Abstract

To determine the genetic polymorphism and the similarities i.e. the differences among Serbian spruce genotypes - lines, this study applies the analysis of in the salts soluble proteins of seeds, starting from the hypothesis that they can be sufficiently informative genetic markers also in the research of Serbian spruce. Taking into account the fact that intra-line variability is a great store of genetic variability, conditioned by the average parental heterozygosity and by the system of pollination, the study was carried out on the seeds obtained by cross-pollination and self-pollination. The determined degree of polymorphism, the recorded inbreeding, inter-line differentiation and a relatively high degree of heterozygosity, indicate the open recombination system of limited character, realised within the Serbian spruce seed orchard at Godovik.
