%X The genetic variability of Scots pine was investigated in six  populations from Poland representing two maternal populations and their  natural and artificial progenies. Thirteen enzyme systems controlled by  25 allozyme loci were analyzed using starch gel electrophoresis. Progeny  populations maintained a high and similar level of genetic variation to  that observed in the maternal populations. As expected, much closer  genetic relationships were observed between maternal populations and  their respective progeny than between the two maternal populations  themselves. Progeny populations had the same major alleles, but differed  in the number of rare alleles. Therefore, probably not all rare alleles  were transferred from the maternal stands to the progenies. In  addition, new rare alleles appeared in the progeny populations, possibly  as a result of external pollen flow into the maternal populations.
