“…In this context, adapted populations need to be ex situ conserved and used for the production of seedlings. In this context, the narrow-crowned Norway spruce ideotype could be used by researchers and professional workers on forest restoration and afforestation activities, in the environmental conditions favorable for Norway spruce, with some of them described in the present study as well as in other previous research [7,35,37,52].…”

“…The average annual temperature is 4.8 °C and the sum of the annual precipitation is 880 mm. The design was incompletely balanced, with 4 replications and 3-9 seedlings per split plot, planted at 2.5 by 2.5 m spacing, in which the descendants of six families (three pendula and three pyramidalis) obtained through open or controlled pollinated in the Stâna de Vale population (the blue circle , in Figure 1) were present [7]. This trial was installed in order to compare the pendula trees with the normal crown form trees and also the adaptability of the hybrids of the two forms of Norway spruce.…”

“…This could be achieved, among other methods, by using genetically improved forest reproductive material (FRM) in plantations [4][5][6]. Additionally, increasingly climatic disturbances affect trees' resistance and their physiological processes [7]. The selection of an adapted population and seed trees inside them represents a chance to increase forest stability and productivity over the next generations of breeding programs by using FRM from these populations [8][9][10][11][12][13][14][15].…”

The research objective was to demonstrate the economic impact of using, in afforestation, forest reproductive materials (FRMs) obtained from seed trees selected in the most valuable Norway spruce populations of the FGRs’ (forest genetic resources’) category. The values obtained for the main growth traits (diameter at breast height (Dbh), tree height (Th), and tree volume (Tv)), both in the FGR and in the closest population (with the same age and growth in similar environmental conditions), were compared. Three comparative trials were analyzed, each belonging to different breeding levels: Open-pollinated (Breţcu, 40 years old), half-sib (Măneciu, 25 years), and full-sib (Comandău, 23 years). The difference in volume/hectare between the FGR and an unimproved neighbor population was economically quantified (€), based on the average price per cubic meter (m3) of spruce wood in Romania; the profit at the end of the rotation period (110 years) was projected taking into account the genetic gain that will result from the use of FRM collected from the FGRs. The average FGR growth results were superior to the unimproved neighbor populations, with 8%–13%, 14%–25%, and 26%–79% for Dbh, Th, and volume/ha, respectively, and the differences increased if the best 10% seed trees of the trials were used. For Th, a five times higher family mean heritability was registered for the pendula trees (compared to pyramidalis) in the half-sib trial, while in the full-sib experiment, the pendula trees (both full and half pendula) again registered higher heritability, but for Dbh, which recommends the pendula selection for different traits in the two trials. These results have led to a rate of profitability between 540 and 3366 €/ha, a value that is predicted to increase until the end of the rotation period, when the genetic gain could generate a profit of 7560 €/ha.

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.
