Search of loci for Pinus pallasiana, Pinus sylvestris var. cretacea Kalenicz. еx Kom., Abies alba trees marking differentiating by high heterozygosity of seed progeny has been conducted. Connection between heterozygosity of plants and expression of phenotypic features female cones was analysed. Comparative analysis of embryo's genetic heterogeneity was conducted and peculiarities of mating system of plants Pinus pallasiana D.Don were ascertained. Comparative analysis of some quality characteristics of fruit and seeds of Robinia pseudoacacia L. trees, which grew on different dumps and different expositions was conducted. Coefficient meanings of genetic distance showed a certain genetic propinquity of Norway spruce and hybrid spruce population, so that's why there are no any genetic reasons to regard P. x fennica as a separate taxon. 25 allozymous variants of 9 enzymes systems of Juniperus excelsa in Crimea were revealed. Reliable differences of the heterozygosity level of clonal archives of Pinus sylvestris pluss trees and two man-made plantations and two natural populations was established. Isoenzymes loci which can be used for trees marking during creating of forest seeds plantations were defined in Pinus pallasiana, P. sylvestris var. cretacea, Abies alba populations. Analysis of 51 pairs of gene loci of 6 enzymes systems of Abies alba let us established the linkage of only three loci pairs. Product Description popup.authors popup.nrat_date 2020-04-02 Close
