P opulus trichocarpa is widespread across western North America spanning extensive
variation in photoperiod, growing season and climate. We investigated trait variation in P . …

In order to uncover the genetic basis of phenotypic trait variation, we used 448 unrelated
wild accessions of black cottonwood (Populus trichocarpa) from much of its range in western …

Establishing links between phenotypes and molecular variants is of central importance to
accelerate genetic improvement of economically important plant species. Our work represents …

Background QTL cloning for the discovery of genes underlying polygenic traits has historically
been cumbersome in long-lived perennial plants like Populus. Linkage disequilibrium-…

Genetic mapping of quantitative traits requires genotypic data for large numbers of markers
in many individuals. For such studies, the use of large single nucleotide polymorphism ( SNP …

… The temporal PA (TPA) is then r(GEBV j , EBV k ), where k is age 40 and j is an age less …
of 2(p j –0.5), and p is the frequency of the alternative allele of the SNP at the j th locus. The …

Stomata are essential for diffusive entry of gases to support photosynthesis, but may also
expose internal leaf tissues to pathogens. To uncover trade‐offs in range‐wide adaptation …

The increasing ecological and economical importance of P opulus species and hybrids has
stimulated research into the investigation of the natural variation of the species and the …

Complete pedigree information is a prerequisite for modern breeding and the ranking of
parents and offspring for selection and deployment decisions. DNA fingerprinting and pedigree …

… where u is intercept, Z is genotype at the i th locus of the j th individual and m is the marker
effect. The accuracy of GS to predict the breeding value (BV) was estimated as the correlation …
