We tested 95 new, geographically informative nuclear SNP loci of pedunculate oak in order to identify genetic differences of populations in the same seed zone. In a cluster analysis all individuals of the two studied stands are divided into two distinct groups. We observed statistically significant genetic differentiation of two populations (genetic distance d_0 = 0.170, parameter of differentiation 〖delta〗_T = 0.1696, genetic fixation F_ST = 0.0687) and higher genetic variability in the lowland stand (P = 91,58%, observed heterozygosity H_O = 0.364, expected heterozygosity H_E = 0.330, diversity of alleles υа = 1.58) in comparison to the oak stand in the Volga uplands (P = 77,89%, H_O = 0.327, H_E = 0.272, υа = 1.47). We concluded that these oak forests should be subdivided into different seed zones. Continuing the research by using the set of SNP loci and expanding the set of studied populations will supply Russian forestry by genetic information to optimize the forest seed zoning of the pedunculate oak. |
