Competition with weeds decreases crop yields globally. Breeding for competitive ability against elevated weed pressure can be difficult because the selection for specific traits which contribute to competitive ability may result in yield losses. The widely studied International Triticeae Mapping...
Differential growth and rooting of upland and peatland black spruce, Picea mariana, in drained and flooded soilsDownload
A reciprocal experiment was analyzed to determine whether 30 open-pollinated families of peatland and upland populations of black spruce [Picea mariana (Mill.) B.S.P.] sampled from a single area in north-central Alberta, Canada, performed consistently when grown in either flooded or well-drained...
We estimated heritabilities and correlations for bud flushing and growth traits of white spruce seedlings, and the correlations of seedling traits with 10- and 11-year height of the same families in the field. The seedling greenhouse experiment had a randomized complete block design with 30...
Genetic variation in height, branch and needle lengths of Pinus sylvestris L. from Siberia tested in Alberta, CanadaDownload
We performed the analysis of variance and covariance on height, branch length, height to branch length ratio, and needle length measurements from thirty open-pollinated families of Pinus sylvestris L. from Siberia, Russia. This progeny trial was replicated on three sites in central Alberta,...
Pork quality and carcass characteristics are now being integrated into swine breeding objectives because of their economic value. Understanding the genetic basis for these traits is necessary for this to be accomplished. The main objective of this study was to improve pork quality traits in two...
Ontogenetic patterns in heritable variation for body size: using random regression models in a wild ungulate populationDownload
Body size is an important determinant of fitness in many organisms. While size will typically change over the lifetime of an individual, heritable components of phenotypic variance may also show ontogenetic variation. We estimated genetic (additive and maternal) and environmental covariance...
Study of early selection in tree breeding - 3. A case study using early information to enhance selection efficiency in late trait in lodgepole pine (Pinus contorta spp. Latifolia)Download
We present a selection procedure that combines early performance from retrospective study and late performance from field testing into an index designed for enhancing the selection efficiency of the late performance. The prerequisite is that early performance from retrospective study and late...
