Integrated genomic selection for rapid improvement of crops

Genomics. 2021 Feb 18:S0888-7543(21)00058-6. doi: 10.1016/j.ygeno.2021.02.007. Online ahead of print.ABSTRACTAn increase in rate of crop improvement is essential for achieving sustained food production and other needs of ever increasing population. Genomic selection (GS) is a potential breeding tool that has been successfully employed in animal breeding and is being incorporated into plant breeding. GS promises accelerated breeding cycles through a rapid selection of superior genotypes. Numerous empirical and simulation studies on GS and realized impacts on improvement in the crop yields are recently being reported. For a holistic understanding of the technology, we briefly discuss the concept of genetic gain, GS methodology, its current status, advantages of GS over other breeding methods, prediction models, and the factors controlling prediction accuracy in GS. Also, integration of speed breeding and other novel technologies viz. high throughput genotyping and phenotyping technologies for enhancing the efficiency and pace of GS, followed by its prospective applications in varietal development programs is reviewed.PMID:33610797 | DOI:10.1016/j.ygeno.2021.02.007
