what is genomic selection in plant breeding

Best answer


Genomic selection (GS) is amethod to predict the genetic value of selection candidatesbased on the genomic estimated breeding value (GEBV) predicted from high-density markers positioned throughout the genome. Unlike marker-assisted selection, the GEBV is based on all markers including both minor and major marker effects.

  • What is the basis of genetic selection in plant breeding?

  • Hence, Genomic selection depends on the degree of genetic similarity between training population and breeding population within the Linkage disequilibrium between marker and trait loci. Breeding values have not been a preferred index in plant breeding, however it is in animal breeding.

  • What is the difference between estimated breeding value and genomic selection?

  • estimated breeding value (GEBV): breeding value of an individual calculated using genome- wide marker data to capture small genetic 1 effects dispersed over the genome. Genomic selection (GS): a type of breeding F1 – inducer methodology that selects the best candidates as parents for the next selection cycle based on their

  • How is genomic selection helpful for accelerate breeding cycles?

  • Moreover, Genomic selection helpful for accelerate breeding cycles in such a way that the rate of annual genetic gain per unit of time and cost can be decreased. Genomic selection has been well established in the field of animal breeding, but is in its beginning in crops plants and forest tree breeding.
