CASSAVA BREEDING I: THE VALUE OF BREEDING VALUE [PDF]

open access: yesFrontiers in Plant Science, 2016
Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials - UYT). This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the

THE RELATIONSHEEP OF THE BREEDING VALUE OF BULLS WITH THE PRODUCTIVITY OF THEIR MOTHERS AND THE BREEDING VALUE OF THEIR PARENTS BREEDING

open access: yesAnimal Breeding and Genetics, 2021
Having a correlation between the pedigree value of the parents and the productivity of the mothers with the pedigree value of the offspring (inheritance through "father-son" and "mother-son") would increase the likelihood of selecting breeders at the stage of custom mating to obtain repair bulls.

Breeding Values in Honey Bees

open access: yesBee 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

open access: yesAnimals, 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

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

open access: yesFrontiers 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.

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

open access: yesAnimal, 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

open access: yesAnimal, 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.

Prediction of haplotypes for ungenotyped animals and its effect on marker-assisted breeding value estimation [PDF]

open access: yes, 2010
Background: In livestock populations, missing genotypes on a large proportion of animals are a major problem to implement the estimation of marker-assisted breeding values using haplotypes.

Evaluation of safflower varieties for productivity and quality in the arid conditions of the Northern Caspian region

open access: yesАграрная наука Евро-Северо-Востока, 2023
In a dry continental climate, safflower has an undeniable advantage over grains and oilseeds due to its morphological structure. The main advantage of this crop is that it is capable of extracting water from deep layers of soil with its developed root ...
