Polimorfizm izoenzymów świerka pospolitego rasy istebniańskiej, tarnawskiej oraz wybranych pochodzeń doświadczenia IPTNS-IUFRO 1964/68 w Krynicy

In this study the genetic structure of Istebna and Tarnawa plus trees was studied and polymorphism of twenty four provenances of spruce tested in a IPTNS−IUFRO 1964/68 site in Krynica representing selected regions of the species occurrence was analyzed. The genetic diversity was estimated with seven isoenzyme systems encoded in eleven loci. The highest genetic polymorphism was shown by plus trees of the Istebna and Tarnawa race and the lowest by spruce from IUFRO experiment. There was a statistically significant effect of origin on the mean number of alleles per locus. The origin of the analyzed trees had no effect on other parameters of genetic variability: the effective number of alleles per locus, observed and expected heterozygosity and Wright index.
