Genotype by environment interaction and breeding for robustness in livestock
The increasing size of the human population is projected to result in an increase in meat consumption. However, at the same time, the dominant position of meat as the center of meals is on the decline. Modern objections to the consumption of meat include public concerns with animal welfare in livestock production systems. Animal breeding practices have become part of the debate since it became ...
متن کاملGenotype - - Environment Interaction
T HE experiment involved 48 pairs of male Holstein fraternal twin calves. Two methods of raising calves were contrasted: (A) High fat (20%) and protein (20%) vealer ration fed from 3 days of age to a market weight of 128 kilograms. (B) The same vealer was fed up to a live weight of 56.7 kg, followed by pelleted grain mixture fed ad libitum and hay offered to a maximum of 0.9 kg per day. Twin pa...
متن کاملEvaluation of Genotype × Environment Interaction for Seed Yield of Sunflower Hybrids using GGE Biplot Method
Extended Abstract Introduction and Objective: The sunflower is one of the most important oilseed plants in the world and its oil has nutritional and high economic value. Identification and selection of high-yielding genotypes with desirable characteristics are especially important in this plant. Evaluating sunflower genotypes under different environmental conditions would be useful to identify...
متن کاملFrom Genotype × Environment Interaction to Gene × Environment Interaction
Historically in plant breeding a large number of statistical models has been developed and used for studying genotype × environment interaction. These models have helped plant breeders to assess the stability of economically important traits and to predict the performance of newly developed genotypes evaluated under varying environmental conditions. In the last decade, the use of relatively low...
متن کاملGenomic Prediction of Breeding Values when Modeling Genotype × Environment Interaction using Pedigree and Dense Molecular Markers
Genomic selection (GS) has become an important aid in plant and animal breeding. Multienvironment (multitrait) models allow borrowing of information across environments (traits), which could enhance prediction accuracy. This study presents multienvironment (multitrait) models for GS and compares the predictive accuracy of these models with: (i) multienvironment analysis without pedigree and mar...
