“…The linkage maps were saturated, with a 10 cM interval between nearest markers. The average distance between nearest markers detected in this study (approximately 4 cM; Table 3) was also comparable with that in previous studies [46,48,50,52]. The maximum marker gap distance in this study (approximately 20 cM) was also similar to that in a previous study [51].…”

“…This result corroborates that of a previous study on Sakhalin fir, in which several QTLs with small or moderate effects (PVE: 3.8-7.4%) were detected for H17 and D16 at the early stage. QTLs with small or moderate effects on growth traits have also been detected in other conifers [46][47][48][49].…”

“…Long generation times and the outbred mating system of conifers were used to construct a suitable mapping population. Because several pedigrees are available for important traits, including height growth and wood properties, in a tree breeding program, secondgeneration populations were used for QTL mapping [46][47][48][49]. However, F 1 pedigrees have been used for QTL mapping of eco-physiological studies in the evolutionary biology of conifers [50,51].…”

(1) Background: The genetic basis of local adaptation in conifers remains poorly understood because of limited research evidence and the lack of suitable genetic materials. Sakhalin fir (Abies sachalinensis) is an ideal organism for elucidating the genetic basis of local adaptation because its altitudinal adaptation has been demonstrated, and suitable materials for its linkage mapping are available. (2) Method: We constructed P336 and P236 linkage maps based on 486 and 516 single nucleotide polymorphisms, respectively, that were derived from double digest restriction site-associated DNA sequences. We measured the growth and eco-physiological traits associated with morphology, phenology, and photosynthesis, which are considered important drivers of altitudinal adaptation. (3) Results: The quantitative trait loci (QTLs) for growth traits, phenology, needle morphology, and photosynthetic traits were subsequently detected. Similar to previous studies on conifers, most traits were controlled by multiple QTLs with small or moderate effects. Notably, we detected that one QTL for the crown area might be a type-A response regulator, a nuclear protein responsible for the cytokinin-induced shoot elongation. (4) Conclusion: The QTLs detected in this study include potentially important genomic regions linked to altitudinal adaptation in Sakhalin fir.

“…For example, Bartholomé et al [63] detected QTLs that explained up to 5% of the total phenotypic variation of ST in maritime pine. Yang et al [64] found QTLs that explained up to 15% of the total phenotypic variation of the stem straightness of Pinus hybrids. Additionally, Arriagada et al [65] reported five QTLs for ST, explaining a total of 6–14% of the total proportion of trait variation in Eucalyptus cladocalyx .…”

Eucalyptus globulus (Labill.) is one of the most important cultivated eucalypts in temperate and subtropical regions and has been successfully subjected to intensive breeding. In this study, Bayesian genomic models that include the effects of haplotype and single nucleotide polymorphisms (SNP) were assessed to predict quantitative traits related to wood quality and tree growth in a 6-year-old breeding population. To this end, the following markers were considered: (a) ~14 K SNP markers (SNP), (b) ~3 K haplotypes (HAP), and (c) haplotypes and SNPs that were not assigned to a haplotype (HAP-SNP). Predictive ability values (PA) were dependent on the genomic prediction models and markers. On average, Bayesian ridge regression (BRR) and Bayes C had the highest PA for the majority of traits. Notably, genomic models that included the haplotype effect (either HAP or HAP-SNP) significantly increased the PA of low-heritability traits. For instance, BRR based on HAP had the highest PA (0.58) for stem straightness. Consistently, the heritability estimates from genomic models were higher than the pedigree-based estimates for these traits. The results provide additional perspectives for the implementation of genomic selection in Eucalyptus breeding programs, which could be especially beneficial for improving traits with low heritability.

Genetic mapping and QTL analysis in European hazelnut (Corylus avellana L.)

et al. 2016

The European hazelnut (Corylus avellana L.) is the most economically important nut species in the Betulaceae family. Despite the need for new improved hazelnut cultivars, few breeding programs are carried out because of the large plant size, the long life cycle of the plant, and the expense and time required. To date, there are no reports of maps with Quantitative Trait Loci (QTL) in hazelnut. Our objective in the present study was to identify QTL associated with vegetative traits to allow marker-assisted selection (MAS). A F1 progeny (275 plants) of 'Tonda Gentile delle Langhe' X 'Merveille de Bollwiller' obtained in 2009 was used to develop a QTL linkage map for vigour, sucker habit and time of bud burst, after three years of observations. A set of 163 plants were analysed with 152 microsatellite markers. A map of 11 linkage groups was obtained, covering 663.1 cM and 15 QTLs were identified and mapped for the examined traits. Among them, 10 were 'major' QTL, including a stably expressed region on LG_02 for leaf budburst. At least one major QTL for each year underlays the variation in each trait and a clustering of QTL for tc and s/tc ratio with a high inter-trait correlations was observed on LG_05, suggesting a single pleiotropic locus. 3 This research represents an initial step for the future identification of chromosomal regions carrying genes of interest, important for breeding programs and MAS.
