Time of flight was also not significantly different from zero for both additive and non-additive effects, respectively. Average single-site heritability estimates (±SE) for wood density and DBH were 0.38 ± 0.10 and 0.16 ± 0.08, respectively. Pooled-site heritability estimates for wood density and DBH were 0.38 ± 0.10 and 0.08 ± 0.10, respectively. For density, there was little evidence of genotype-by-environment interaction (GEI) across the eight trials at the additive level (type B additive genetic correlation; r BADD = 0.73 ± 0.08) and type B genetic correlation for full-sib families (r BFS = 0.64 ± 0.08). In contrast, the type B additive genetic correlation for DBH was lower, (r BADD = 0.51 ± 0.14), suggesting evidence of GEI. However, type B genetic correlation for full-sib families was moderate (0.63 ± 0.11) for DBH, suggesting that there may be some stable full-sib families. On the basis of the results of this study, GEI should be considered in order to optimise deployment of improved germplasm in Australia.

To investigate how seed dormancy is controlled, quantitative trait loci (QTL) analyses has been performed in six Arabidopsis thaliana recombinant inbred line populations by analyzing them simultaneously using a mixed model QTL approach. The recombinant inbred line populations were derived from crosses between the reference accession Landsberg erecta (Ler) and accessions from different world regions. In total, 11 delay of germination (DOG) QTL have been identified, and nine of them have been confirmed by near isogenic lines (NILs). The absence of strong epistatic interactions between the different DOG loci suggests that they affect dormancy mainly by distinct genetic pathways. This was confirmed by analyzing the transcriptome of freshly harvested dry seeds of five different DOG NILs. All five DOG NILs showed discernible and different expression patterns compared with the expression of their genetic background Ler. The genes identified in the different DOG NILs represent largely different gene ontology profiles.

Timing of germination is presumably under strong natural selection as it determines the environmental conditions in which a plant germinates and initiates its postembryonic life cycle. To investigate how seed dormancy is controlled, quantitative trait loci (QTL) analyses has been performed in six Arabidopsis thaliana recombinant inbred line populations by analyzing them simultaneously using a mixed model QTL approach. The recombinant inbred line populations were derived from crosses between the reference accession Landsberg erecta (Ler) and accessions from different world regions. In total, 11 delay of germination (DOG) QTL have been identified, and nine of them have been confirmed by near isogenic lines (NILs). The absence of strong epistatic interactions between the different DOG loci suggests that they affect dormancy mainly by distinct genetic pathways. This was confirmed by analyzing the transcriptome of freshly harvested dry seeds of five different DOG NILs. All five DOG NILs showed discernible and different expression patterns compared with the expression of their genetic background Ler. The genes identified in the different DOG NILs represent largely different gene ontology profiles. It is proposed that natural variation for seed dormancy in Arabidopsis is mainly controlled by different additive genetic and molecular pathways rather than epistatic interactions, indicating the involvement of several independent pathways.

@article{sanchez_effect_2010, title = {Effect of selection method on genetic correlation and gain in a two-trait selection scheme}, volume = {74}, doi = {10/f2467c}, abstract = {Adverse genetic correlations between wood volume and quality traits are one of the main constraints in advancing radiata pine and other pine breeding programs. To overcome or deal with adverse genetic correlation in radiata pine and other conifer breeding programs, a Monte Carlo simulation study for the adversely correlated traits DBH and wood density was conducted using allele-based models. Two allelic models were generated for the study: a mixed-loci model using independent and pleiotropic loci (i.e. each locus affecting more than one trait) for adversely correlated traits and an all-antagonistic-pleiotropic-loci model. Selection was conducted for three scenarios: the first was based on a single trait, the second on index selection for two adversely correlated traits (DBH and wood density) with equal or, third, unequal economic weights. Results indicated that: 1. Adverse genetic correlation tends to increase under pleiotropic models with selection. 2. Genetic gains for adversely correlated traits (such as DBH and wood density) could be made for many generations with selective breeding if there are independent loci for individual traits. 3. New alleles (from infusion or mutation) with less antagonistic effect are required for further genetic gain in the two adversely correlated traits simultaneously if all independent alleles are fixed (i.e. without allelic variation) and pleiotropic loci with antagonistic effects are not fixed. 4. For short-term genetic gain in adversely correlated traits, selection based on two traits simultaneously is more effective than selection based on a single trait. Developing economic weights through breeding objectives is a sound approach for short-term breeding programs. Economic weights will influence genetic gain for individual traits and genetic correla tion between traits. 5. For long-term genetic gain, dissecting the genetic basis of traits using a large association population is recommended.

Adverse genetic correlations between wood volume and quality traits are one of the main constraints in advancing radiata pine and other pine breeding programs. To overcome or deal with adverse genetic correlation in radiata pine and other conifer breeding programs, a Monte Carlo simulation study for the adversely correlated traits DBH and wood density was conducted using allele-based models. Two allelic models were generated for the study: a mixed-loci model using independent and pleiotropic loci (i.e. each locus affecting more than one trait) for adversely correlated traits and an all-antagonistic-pleiotropic-loci model. Selection was conducted for three scenarios: the first was based on a single trait, the second on index selection for two adversely correlated traits (DBH and wood density) with equal or, third, unequal economic weights. Results indicated that: 1. Adverse genetic correlation tends to increase under pleiotropic models with selection. 2. Genetic gains for adversely correlated traits (such as DBH and wood density) could be made for many generations with selective breeding if there are independent loci for individual traits. 3. New alleles (from infusion or mutation) with less antagonistic effect are required for further genetic gain in the two adversely correlated traits simultaneously if all independent alleles are fixed (i.e. without allelic variation) and pleiotropic loci with antagonistic effects are not fixed. 4. For short-term genetic gain in adversely correlated traits, selection based on two traits simultaneously is more effective than selection based on a single trait. Developing economic weights through breeding objectives is a sound approach for short-term breeding programs. Economic weights will influence genetic gain for individual traits and genetic correla tion between traits. 5. For long-term genetic gain, dissecting the genetic basis of traits using a large association population is recommended. When the genetic mechanisms controlling adversely correlated traits are better understood, an allele model could be developed to study optimal strategies under different gene actions.
