Delineation of beech provenance regions in Serbia by spatial analysis of genetic diversity

Abstract

The results of spatial analysis of genetic diversity have practical application in the definition and delineation of regional provenances of forest trees. Research in this paper, was based on the material from 27 natural populations of beech in Serbia. The genetic component of the research is based on the analysis of RAPD markers from bulk samples, using 28 primers. The spatial component of the research is based on the geographical position of the studied populations. Grouping of the studied populations in the regions, as well as their separation, was performed using the Monmonier’s algorithm of maximum differences. To visualize the results and mapping the regions of beech provenances in Serbia, GIS was used, with database included the results of this study.

Rezultati prostorne analize genetičkog diverziteta imaju praktičnu primenu u definisanju i razgraničenju regiona provenijencija šumskih vrsta drveća. Istraživanja u ovom radu, obuhvatila su materijal iz 27 prirodnih populacija bukve u Srbiji. Genetička komponenta istraživanja bazira se na analizi RAPD markera iz zbirnih uzoraka, korišćenjem 28 prajmera. Prostorna komponenta istraživanja, bazira se na geografskom položaju ispitivanih populacija. Grupisanje ispitivanih populacija u regione, kao i njihovo razgraničenje, izvršeno je primenom Monmonierovog algoritma najvećih razlika. Za vizualizaciju rezultata i izradu karata regiona provenijencija bukve u Srbiji, korišćen je GIS, čija je baza podataka obuhvatila rezultate navedenih istraživanja.
