Breeding Values in Honey Bees

Bee World, 2023
This article continues our series on the basics of honey bee breeding (Uzunov et al., Citation2017, Citation2022a, Citation2022b). Its purpose is to introduce the background and application of breeding values in honey bees to a readership that is not trained in quantitative genetics.

Sire Breed, Litter Size, and Environment Influence Genetic Potential for Lamb Growth When Using Sire Breeding Values

Animals, 2022
Lamb growth can be optimised with genetic selection using sire Australian sheep breeding values, however, breeding value expression has been shown to be reduced with poor nutrition. It was therefore hypothesised that the genetic potential for lamb growth

Advanced optimum contribution selection as a tool to improve regional cattle breeds: a feasibility study for Vorderwald cattle

Animal, 2020
In the middle of the 20th century, increasing inbreeding rates were identified as a threat to livestock breeding. Consequences include reduced fertility, fitness and phenotypic expression of lethal alleles. An important step in mitigating this inbreeding

Implementation of advanced Optimum Contribution Selection in small-scale breeding schemes: prospects and challenges in Vorderwald cattle

Animal, 2020
Vorderwald cattle are a regional cattle breed from the Black Forest in south western Germany. In recent decades, commercial breeds have been introgressed to upgrade the breed in performance traits.

Molecular and phenotypic profiling of white Guinea yam (Dioscorea rotundata) breeding lines

Frontiers in Horticulture, 2023
Phenotypic and genotypic profiling helps identify genotypes with suitable and complementary traits for genetic improvement in crops. A total of 32 traits were assessed in 36 genotypes of white Guinea yam established in a 6 × 6 triple lattice design.

Reliabilities of estimated breeding values in models with metafounders

Genetics Selection Evolution, 2023
AbstractBackgroundReliabilities of best linear unbiased predictions (BLUP) of breeding values are defined as the squared correlation between true and estimated breeding values and are helpful in assessing risk and genetic gain. Reliabilities can be computed from the prediction error variances for models with a single base population but are undefined ...
