Evaluation of Linear Programming and Optimal Contribution Selection Approaches for Long-Term Selection on Beef Cattle Breeding [PDF]
Biology, 2023 The optimized selection method can maximize the genetic gain in offspring under the premise of controlling the inbreeding level of the population. At present, genetic gain has been largely improved by using genomic selection in multiple farm animals ...

The effect of genomic information on optimal contribution selection in livestock breeding programs. [PDF]
Genet Sel Evol, 2013 BACKGROUND: Long-term benefits in animal breeding programs require that increases in genetic merit be balanced with the need to maintain diversity (lost due to inbreeding). This can be achieved by using optimal contribution selection. The availability of

How to achieve a higher selection plateau in forest tree breeding? Fostering heterozygote × homozygote relationships in optimal contribution selection in the case study of Populus nigra [PDF]
Evolutionary Applications, 2021 In breeding, optimal contribution selection (OCS) is one of the most effective strategies to balance short‐ and long‐term genetic responses, by maximizing genetic gain and minimizing global coancestry.

Optimal Contribution Selection Improves the Rate of Genetic Gain in Grain Yield and Yield Stability in Spring Canola in Australia and Canada [PDF]
Plants, 2023 Crop breeding must achieve higher rates of genetic gain in grain yield (GY) and yield stability to meet future food demands in a changing climate. Optimal contributions selection (OCS) based on an index of key economic traits should increase the rate of ...

A fast Newton-Raphson based iterative algorithm for large scale optimal contribution selection. [PDF]
Genet Sel Evol, 2016 The management of genetic variation in a breeding scheme relies very much on the control of the average relationship between selected parents. Optimum contribution selection is a method that seeks the optimum way to select for genetic improvement while ...

Evolving gene banks: improving diverse populations of crop and exotic germplasm with optimal contribution selection. [PDF]
J Exp Bot, 2017 For the first time in self-pollinating crops, we apply optimal contribution selection to manage long-term genetic gain and genetic diversity in pre-breeding populations known as evolving gene banks.

Increased genetic gains in sheep, beef and dairy breeding programs from using female reproductive technologies combined with optimal contribution selection and genomic breeding values. [PDF]
Genet Sel Evol, 2015 BackgroundFemale reproductive technologies such as multiple ovulation and embryo transfer (MOET) and juvenile in vitro embryo production and embryo transfer (JIVET) can boost rates of genetic gain but they can also increase rates of inbreeding ...
