Abstract Purpose of Review In this review, we synthesise current knowledge on trade-offs among traits in key fitness dimensions and identify major research gaps with the intention laying groundwork for a rapid advance tree breeding multiple objectives as contribution to sustainability planted forests future. Recent Findings Trade-offs growth, reproduction, defence, stress tolerance product quality predicted theoretically have been reported experimentally many programmes. Among these...
Potential improvement of lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) solid-wood properties was examined by estimating age trends inheritance, age–age genetic correlations, and the efficiency early selection using 823 increment cores sampled from 207 half-sib families at two independent progeny trials, aged 34–35 years, located in northern Sweden. High-resolution radial variation annual ring width, wood density, microfibril angle (MFA), modulus elasticity (clearwood...
The summer drought of 2018 was one the most climatically severe events in Europe that led to record-breaking temperatures and wildfires many parts Europe. main objective this study assess impact on phenotypic genetic response Norway spruce height growth using Standardized Precipitation-Evapotranspiration Index (SPEI). To achieve this, total cumulative about 6000 clones from 2016 2019 four full-sib trials Sweden, aged 6–7 years, 2017 two half-sib Finland, 8–9 were measured. results indicate...
Genetic parameters, performance of provenances, and genotype by environment interaction (G × E) for diameter at breast height (DBH), survival, modulus elasticity time-of-flight (MOEtof) (an indirect measure stiffness), were investigated in six lodgepole pine progeny trials, aged 33–36 years, within three breeding zones northern Sweden. Provenances Yukon origin had the highest growth but lowest stiffness higher latitude, while those British Columbia (BC) grew faster lower latitudes zone 5....
Genetic control of microfibril angle (MFA) transition from juvenile wood to mature was evaluated in Norway spruce (Picea abies (L.) Karst) and lodgepole pine (Pinus contorta Douglas ex Loudon). Increment cores were collected at breast height (1.3 m) 5664 trees two 21-year-old progeny trials southern Sweden 823 trials, aged 34–35 years, northern Sweden. Radial variations MFA pith bark measured for each core using SilviScan. To estimate wood, a threshold level 20° considered, six different...
Quantitative genetic variation of fiber-dimension traits and their relationship with diameter at breast height (DBH) solid-wood (i.e., density modulus elasticity (MOE)) was investigated in lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.). A total 823 increment cores were sampled from 207 half-sib families two independent progeny trials, aged 34–35 years, located northern Sweden. High-resolution pith-to-bark profiles obtained for radial fiber width (RFW), tangential...
We used a regression model approach to examine transferability of the 1.5-generation Swedish Scots pine orchard plus trees using estimated coefficients transfer models recently developed for growth and survival unimproved in Sweden Finland. Differences between observed predicted values obtained height 3214 tree progenies, tested at 58 progeny trials, were regressed on latitudinal transfers (∆LAT). In order evaluate rates improvement selected progenies over trees, average percentage...
Abstract Background Forest geneticists typically use provenances to account for population differences in their improvement schemes; however, the historical records of imported materials might not be very precise or well-aligned with genetic clusters derived from advanced molecular techniques. The main objective this study was assess impact marker-based structure on parameter estimates related growth and wood properties trade-offs Norway spruce, by either incorporating it as a fixed effect...
Abstract Genetic control of microfibril angle (MFA) transition from juvenile to mature was evaluated in Norway spruce and lodgepole pine. Increment cores were collected at breast height 5,618 trees two 21-year-old progeny trials southern Sweden, 823 34-35 – year-old pine northern Sweden. Radial variations MFA pith bark measured for each core using SilviScan. To estimate mature, a threshold level 20° considered six different regression functions fitted the profile tree after exclusion...
Abstract Climate change possess a threat to forests and forestry. Drought has been identified as one of the main issues due its interaction with other biotic abiotic stresses. Few studies have done regarding breeding effect on adaptability climate change. After common garden experiment seedling families Scots pine from northern Sweden, we found differences in drought tolerance between natural origin. We performed high throughput analysis-based phenotyping both canopy root traits. Root...
