Genetic variation at 12 allozyme loci (10 of them being polymorphic ones) has been studied in the archive-clone plantation of 23 Pinus sylvestris plus-trees and their seed progeny in the south-east of Ukraine. More than a half of clones had 4-8 heterozygous loci, whereas their seed progeny was marked by a lower variation than maternal trees. Seed progeny was obtained at a high outcrossing rate (t(m) = 95%). The clone progeny was characterized by a high percentage of abnormal allele segregation in megagametophytes. There was also a high frequency of significant deviation in distribution of seed embryo genotypes from the theoretically expected one according to the Hardy-Weinberg law.
对乌克兰东南部23株欧洲赤松优树及其种子后代的档案克隆种植园中的12个等位酶位点（其中10个为多态性位点）的遗传变异进行了研究。超过一半的克隆具有4 - 8个杂合位点，而它们的种子后代的变异程度低于母树。种子后代是在高异交率（tm = 95%）下获得的。克隆后代的特征是大孢子体中等位基因异常分离的比例很高。根据哈迪-温伯格定律，种子胚基因型的分布也有很高频率显著偏离理论预期。
