Genetic Gain and Inbreeding from Genomic Selection in a Simulated Commercial Breeding Program for Perennial Ryegrass.
Genomic selection (GS) provides an attractive option for accelerating genetic gain in perennial ryegrass () improvement given the long cycle times of most current breeding programs. The present study used simulation to investigate the level of genetic gain and inbreeding obtained from GS breeding strategies compared with traditional breeding strategies for key traits (persistency, yield, and fl...
متن کاملAccuracy of Genomic Prediction in a Commercial Perennial Ryegrass Breeding Program.
The implementation of genomic selection (GS) in plant breeding, so far, has been mainly evaluated in crops farmed as homogeneous varieties, and the results have been generally positive. Fewer results are available for species, such as forage grasses, that are grown as heterogenous families (developed from multiparent crosses) in which the control of the genetic variation is far more complex. He...

With more and more Single Nucleotide Polymorphisms (SNPs) being identified throughout the genome, some of those SNPs will be found to be located within candidate genes, allowing the researchers to use the candidate gene approach on a genomewide scale. SNPs have some drawbacks but when compared to other markers they are more efficient and SNP consortium is growing to meet the requirements of gen...

متن کاملEconomic evaluation of genomic selection in small ruminants: a sheep meat breeding program.
Recent genomic evaluation studies using real data and predicting genetic gain by modeling breeding programs have reported moderate expected benefits from the replacement of classic selection schemes by genomic selection (GS) in small ruminants. The objectives of this study were to compare the cost, monetary genetic gain and economic efficiency of classic selection and GS schemes in the meat she...
