what is genomic selection in plant breeding

Best answer


Genomic Selection (GS) is a method in plant breeding topredict the genetic value of untested lines based on genome-wide marker data. The method has been widely explored with simulated data and also in real plant breeding programs. However, the optimal strategy and stage for implementation of GS in a plant-breeding program is still uncertain.

  • 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 genomic selection and why is it important?

  • Genomic selection has a clear-cut advantage over pedigree breeding and MAS to enhance genetic gains for complex traits. The appropriate use of genotyping platforms combined with precise phenotyping platforms will also help enhance prediction accuracy and accelerate genetic gains by shortening the breeding cycle.

  • Can genomic selection reduce the breeding interval cycle?

  • India, and Mexico has shown that genomic selection can reduce the breeding interval cycle to at least half conventional time and produces lines that, in hybrid combinations, sig- ni铿乧antly increase grain yield perfor- mance over that of commercial checks.
