Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | A comparative analysis of reproduction of the level of genetic variation observed year after year in the seed progeny of the Pinus pallasiana natural population was made. As the genetic markers, isozymes of 2 enzymous systems were used. No valid allele and genotypic heterogeneity was detected between the mother plants of P. pallasiana and their two-year old posterity, but a decrease in the level of heterozygosity in generations was observed. So, the deficit of heterozygotes was 6 and 19,2 % for the seed progeny of P. pallasiana in 1996 and 1997 years respectively. True allele and genotypic heterogeneity was detected between P. pallasiana posterity of the either year, that may be accounted for by the different roles of the cross- and selfpollination of the trees in two years of observation. |
