Genetic diversity and genetic differentiation among Polish populations of Norway spruce (<em>Picea abies</em> (L.) Karst.) were studied analyzing allozyme variation at 24 loci. Presented investigations based on 81 clones represented 6 populations from three different regions: Sudety Mts., Beskid Mts. and North-East Poland. On average, the expected heterozygosity was 0.134, 52.8% of loci were polymorphic, and the number of alleles per locus was 1.8. Our data confirm the hypothesis that a lower level of variation of <em>Picea abies</em> exists in central Europe, compared to other regions of its natural distribution. Relatively small allozyme differentiation among regions was observed (Fst =0.027, and Nei's genetic distances ranged from 0.005 to 0.008). Reasons for the low genetic differentiation observed between Southern and Northern populations are briefly discussed.

The knowledge of genetic diversity degree of given species is of great importance for the successful process of breeding and genetic conservation. The aim of conducted research was to determine the genetic differentiation of Norway spruce (Picea abies (L.) Karst) genotypes with very specific narrow pyramidal and normal crown type, which grows at different altitude of the mountain Golija. For assessment of genetic similarities or differences between studied genotypes co-dominant microsatellite system had been used. This system has proven to be reliable and efficient in the genetic characterization of plant species. In total 22 primer sets have been tested, while 16 (73%) of them resulted in the successful yield of the amplified product. The analysis show that studied individuals had in total 130 alleles, in average 8.125 polymorphic alleles per each locus. The lowest polymorphism was detected in the locus EATC1D10, EATC1F03B and EATC2G09, while the highest level of polymorphism was detected in EATC2G08. Based on microsatellite date and similarity matrix, cluster analysis dendrogram indicates existence of the vertical differentiation of studied genotypes, which is consistent with results of previous Norway spruce studies.

Coffea canephora Pierre ex Frohener is a perennial plant originated from Africa. Two main groups, Guinean and Congolese, have already been identified within this species. They correspond to main refugia in western and central Africa. In this paper we present the analysis of a region that has not yet been studied, Uganda. Two wild, one feral (once cultivated but abandoned for many years), and two cultivated populations of C. canephora from Uganda were evaluated using 24 microsatellite markers. Basic diversity, dissimilarity and genetic distances between individuals, genetic differentiation between populations, and structure within populations were analysed. Expected heterozygosity was high for wild compartments (0.48 to 0.54) and for cultivated and feral ones (0.57 to 0.59), with the number of private alleles ranging from 12 for cultivated genotypes to 37 for a wild compartment. The Ugandan samples show significant population structuring. We compared the Ugandan populations with a representative sample of known genetic diversity groups within the species using 18 markers. Coffea canephora of Ugandan origin was found to be genetically different from previously identified diversity groups, implying that it forms another diversity group within the species. Given its large distribution and extremely recent domestication, C. canephora can be used to understand the effect of refugia colonization on genetic diversity.
