Prediction of Genetic Gains from Selection in Tree Breeding
نویسندگان
چکیده
The prediction of genetic gain from artificial selection in a trait is important plant and animal breeding. Lush’s classical breeder’s equation (BE) widely used for this purpose, although it also applied to predicting evolution under natural selection. current application high throughput sequencing techniques potentially allows breeders at the individual gene level capture both additive non-additive effects. Here, we provide comprehensive evaluation gains multiple hierarchical levels population structure (provenances, families within provenances, individuals provenances). We discuss processes that could influence power BE, including drift, selection, flow. extend BE molecular breeding methods improving gains; they include conventional approach, marker-assistant (MAS), genome-wide association study (GWAS), genomic (GS). Lastly, using multi-omics traits, expression epigenetic traits. Our overall synthesis should contribute better understanding

Genomic selection in tree breeding: testing accuracy of prediction models including dominance effect
Background The concept of Marker Assisted Selection (MAS) is rapidly evolving in animal and plant breeding. With the advent of high throughput molecular technology, numerous molecular markers distributed throughout the whole genome can be produced to characterize many genetic entries involving new perspectives in methodology of selection. An important research activity has begun in the animal w...

Advances in Maize Genomics and Their Value for Enhancing Genetic Gains from Breeding
Maize is an important crop for food, feed, forage, and fuel across tropical and temperate areas of the world. Diversity studies at genetic, molecular, and functional levels have revealed that, tropical maize germplasm, landraces, and wild relatives harbor a significantly wider range of genetic variation. Among all types of markers, SNP markers are increasingly the marker-of-choice for all genom...
