Norway spruce, Picea abies (L.) Karst. is the most important conifer species in Romania and the most planted tree species in the Carpathian Mountains. Here we compare the genetic diversity of four Norway spruce clonal seed orchards and two seed stands located in the Eastern Carpathians. A set of highly polymorphic nuclear microsatellite markers was used. The analysis of genotypic identity of ramets for each Norway spruce clone in all seed orchards indicated that nearly all sampled ramets (97%) were genetically identical. The genetic diversity in seed orchards (He=0.700) was slightly smaller compared to the seed stands (He=0.718). Allelic richness was higher in seed stands (10.874), compared to clonal seed orchards (8.941). The Bayesian analysis indicated a genetic structure with two clusters, one corresponding to the clonal seed orchards and a second one consisting of the two seed stands. Our results provide valuable information for the management of Norway spruce seed orchards in Romania.

The alternate host range of cherry-spruce rust is poorly studied although such information could be important in protecting spruce seed orchards from infections. Pathogenicity of cherry-spruce rust, (Fr.) Magnus, was investigated on potential alternate host species in a greenhouse and in a laboratory in Finland. Five common species of Ericaceae, L., L., L., L. and (L.) Spreng, were inoculated in the greenhouse using aeciospores from seven Norway spruce [ (L.) H. Karst.] seed orchards suffering from in 2018. In addition, young detached leaves of spp. and 17 other plant species of ground vegetation from eight Norway spruce seed orchards were inoculated with aeciospores from six seed orchards in the laboratory in 2019. Also, young leaves of L. trees growing within the seed orchards or close to them were inoculated as controls. None of the inoculated leaves of the potential alternate hosts formed uredinia either in the greenhouse or in the laboratory. In contrast, leaves of from the seed orchards were infected by the six spore sources from six seed orchards and produced uredinia. As spores were able to infect only , but not the other tested species belonging to ground flora, it was concluded that disperses only via spp. in Finnish seed orchards.Thekopsora areolataVaccinium myrtillusV. uliginosumV. vitis-idaeaEmpetrum nigrumArctostaphylos uva-ursiPicea abiesT. areolataVacciniumPrunus padusP. padusT. areolataP. padusT. areolataPrunus
