“…is one of the dominant forest tree species in Northern Europe, and also one of the most severely impacted by the pine weevil (Wallertz et al 2014). Surprisingly, despite the huge effort for improving growth and timber properties that has been done in this species across multiple countries (Jansson et al 2013), to our best knowledge, no single attempt has been done to explore whether resistance of Norway spruce to the pine weevil is genetically variable and can be enhanced by conventional selection and breeding. Results from breeding programs in Eastern Canada has revealed large genetic variation in Norway spruce in resistance traits against another weevil (the white pine weevil P. strobi), with most of this variation being additive (Mottet et al 2015).…”

“…Despite the lack of information on genetic variation in resistance to the pine weevil for northern conifer species, significant additive variation in resistance has been reported in Mediterranean pines of Southern Europe, such as the native Pinus pinaster Aiton (Zas et al 2005) and the exotic Pinus radiata D. Don (Zas et al 2008). Since Norway spruce is a species characterized by high genetic diversity and low population differentiation (Jansson et al 2013), it seems reasonable to expect a significant intraspecific variation in resistance to H. abietis.…”

Regeneration of northern conifer forests is commonly performed by reforestation with genetically improved materials obtained from long-term breeding programs focused on productivity and timber quality. Sanitary threats can, however, compromise the realization of the expected genetic gain. Including pest resistance traits in the breeding programs may contribute to a sustainable protection. Here we quantified the variation in different components of resistance of Norway spruce to its main pest, the pine weevil Hylobius abietis. We followed insect damage in two large progeny trials (52 openpollinated families with 100-200 individuals per family and trial) naturally infested by the pine weevil. Pine weevils damaged between 17 and 48% of the planted seedlings depending on the trial and year, and mortality due to weevil damage was up to 11.4%. The results indicate significant genetic variation in resistance to the pine weevil, and importantly, the variation was highly consistent across trials irrespective of contrasting incidence levels. Individual heritability estimates for the different components of seedling resistance were consistently low, but family heritabilities were moderate (0.53 to 0.81). While forward selections and breeding for higher resistance seem not feasible, backwards selections of the best parent trees emerge as a putative alternative to reduce weevil damage. A positive genetic correlation between early growth potential and probability of being attacked by the weevil was also observed, but the relationship was weak and appeared only in one of the trials. Overall, results presented here open the door to a new attractive way for reducing damage caused by this harmful pest.

Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is one of the major commercial conifer species in China. The present study concentrated on the assessment of growth, wood property traits, and strobili number in a 12-year grafted clone test of 62 Chinese fir breeding parents, aiming to describe the variation and correlations between these traits and to identify parent clones with the highest potential for future breeding. The results indicate that all of the growth (height, diameter at breast height, stem volume, crown-width) and wood property (wood basic density and hygroscopicity) traits varied significantly (p < 0.01) among clones, with coefficients of variation ranging from 7.6% to 30.6%. Furthermore, these traits consistently had a moderate to high (0.39-0.87) repeatability estimate (broad-sense heritability). Remarkable clonal differences were also observed for the production of male and female strobili. Phenotypic correlations among growth traits were strong (p < 0.01) and positive. Significantly negative correlations (p < 0.01 or 0.05) were found between wood basic density and growth (except for height) and hygroscopicity. The production of male and female strobili appeared to be significantly (p < 0.01) positively correlated with each other. A notable number of faster-growing parent clones were identified (n = 30); 11 of these had higher density wood with an average realized gain of 10.5% in diameter, and a 5.4% gain in wood basic density. When selection was made for growth and strobili, 10 faster-growing parent clones with medium to high production of female strobili were identified. OPEN ACCESSForests 2015, 6 3800

“…Regardless of whether connectivity is increased for example by assisted migration of genotypes among populations or decreased via fragmentation, there is the potential that subsequent genetic changes may influence associated communities. Throughout Europe, the management of Norway spruce includes the extensive transfer of genetic material (Jansson et al, ). Furthermore, assisted migration of forest trees is now considered as a management option in various regions, for example Canada (Winder, Nelson, & Beardmore, ), Europe (Benito‐Garzón & Fernández‐Manjarrés, ), and the United States (Grady et al, ).…”

The extended consequences of genetic conductivity: Mating distance affects community phenotypes in Norway spruce

Anthropogenic landscape‐level alterations such as habitat fragmentation and long distance translocation of genetic material are currently altering the genetic connectivity and structure of forest tree populations globally. As the susceptibility of individual trees to dependent organisms is often genetically determined, it is possible that these genetic changes may extend beyond individuals to affect associated communities. To test this, we examined how variation in crossing distance among the progeny of 18 controlled crosses of Norway spruce (Picea abies) populations occurring across central Sweden affected chemical defense, and subsequently, a small community of galling Adelges aphids infecting planted trees at two common garden trails. Although crossing distance did not influence growth, vitality or reproduction in the studied population, it did influence the expression of one candidate defensive chemical compound, apigenin, which was found in higher concentrations within outcrossed trees. We also show that this variation in apigenin induced by crossing distance correlated with susceptibility to one member of the galling community but not the other. Furthermore, the effect of crossing distance on galling communities and the general susceptibility of Norway spruce to infection also varied with environment. Specifically, in the more benign environment, inbred trees suffered greater gall infection than outcrossed trees, which is contrary to general predictions that the effects of inbreeding should be more pronounced in harsher environments. These findings suggest that the effects of variation in crossing distance in forest trees can extend beyond the individual to influence whole communities.
