Quantitative genetics--empirical results relevant to plant breeding
TL;DR: This chapter focusses on reviewing and interrelating recent research results in areas of most significance to plant breeders, such as kinds of genetic variability found, effects of inbreeding and crossbreeding, genotype-environmental interaction, and selection methodology and response.
Journal ArticleDOI
Improvement of metric traits through specific genetic loci
TL;DR: There appear to be no loci that could be used with confidence in the improvement of economic traits in farm animals, but the evidence is often inconsistent and contradictory.
Journal ArticleDOI
Design of Screening Procedures: A Review
Kwei Tang,Jen Tang +1 more
TL;DR: It has been well accepted that dependence on inspection to correct quality problems is ineffective and costly, and hence screening (100% inspection) should not be used as a long-term solution for quality problems.
Journal ArticleDOI
Genetics of wood stiffness and its component traits in Pinus radiata
TL;DR: The potential for breeding Pinus radiata D. Don to improve wood stiffness (modulus of elasticity, MoE) was examined by obtaining pith-to-bark cores from trees at breast height in two independent studies.
Journal ArticleDOI
Very early selection for solid wood quality: screening for early winners.
TL;DR: In this paper, the theoretical basis for indirect selection and correlated response is calculated, followed by a description of issues as to the choice of selection criteria that could explain the lack of substantial progress on breeding for wood quality.

The Genetic Basis for Constructing Selection Indexes
TL;DR: "The key is man9s power of accumulative selection: nature gives successive variations; man adds them up in certain directions useful to him."
Journal ArticleDOI
Phenotypic, genetic and environmental correlations
S. R. Searle,N. Z. Dairy +1 more
TL;DR: This paper investigated the relationship between these three correlations on the basis of a linear model, and demonstrates the situations in which this explanation is correct, and showed that the explanation is the result of a negative environmental correlation in the records of the two traits.
Journal ArticleDOI
Genotype and Environment in Sire Evaluation
TL;DR: Application of the formula for relative genetic progress indicates that it may be advantageous to evaluate sires from daughter performance in all except the low-level herds, and it seems preferable not to exclude any herds unless contract herds were being used to test young sires.
Journal ArticleDOI
Relations between Parts of Lactations and Producing Ability of Holstein Cows
TL;DR: The relations between various parts of completed lactation of at least 243 days duration were considered in 599 lactations of 253 Holstein cows in the Iowa State College herd, with efficiency values ranging from 0.74 to above unity.
