delivers more accurate predictions. Selection can be based on genomic selection predictions, potentially leading to more rapid and lower cost gains from breeding. Genomic prediction combines marker data with phenotypic and pedigree data (when available) in an attempt to increase the accuracy of the prediction of breeding and genotypic values.

genomic selection. More often, however, molecular breeding implies molecular marker-assisted breeding (MAB) and is defined as the application of molecular biotechnologies, specifically molecular markers, in combination with linkage maps and genomics, to alter and improve plant or animal traits on the basis of genotypic assays.

and animal breeding. In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted selection, and

Genomic selection is a novel approach to traditional marker-assisted selection where selection is made based on only a few markers. Rather than seeking to identify individual loci significantly associated with a trait, genomics uses all marker data as predictors of performance and consequently

Backcrossing is crossing an F1 with its parents to transfer a limited number of loci (e.g. transgene, disease resistance loci, etc.) from one genetic background to another. Usually the recipient of such genes is a cultivar that is already well performing - except for the gene that is to be
150:
Genes (Quantitative trait loci (abbreviated as QTL) or quantitative trait genes or minor genes or major genes) involved in controlling trait of interest are identified. The process is known as mapping. Mapping of such genes can be done using
220:
Transfer of genes makes possible the horizontal transfer of genes from one organism to another. Thus plants can receive genes from humans or algae or any other organism. This provides limitless opportunities in breeding crop plants.
137:. The "omics" for measurement of phenotypes is called phenomics. The phenotype can be indicative of the measurement of the trait itself or an indirectly related or correlated trait.
183:
transferred. So we want to keep the genetic background of the recipient genotypes, which is done by 4-6 rounds of repeated backcrosses while selecting for the gene of interest.
159:). The basic idea is to identify genes or markers associated with genes that correlate to a phenotypic measurement and that can be used in marker assisted breeding / selection.
