Genomic Selection in Plant Breeding

Plant breeding has undergone a revolutionary shift with the introduction of genomic selection (GS), whichGenomic selection (GS) has surpassed conventional selection techniques. GS uses genome-wide markers to determine genomic-estimated breeding valuesBreeding value (GEBV), which drives a productive approach to finding candidates for future breeding cycles. By utilizing the power of genetically guided approach, this ground-breaking method enables breeders to enhance quantitative traits, such as yield, stress tolerance, and quality—attributes controlled by polygenes with minute impacts. A paradigm change is evident in the switch from traditional selection methods to genetic selection (GS), which emphasizes a more accurate and thorough knowledge of the genetic foundations of traitsTraits of interest. The foundation of GS is made up of statistical methods and instruments that help to decode the complicated genomicGenomics architecture intrinsic complex characteristics. Breeders are able to choose individuals with excellent genomic profiles more quickly and more efficiently through the use of GEBVGenomic estimated breeding value (GEBVs). The current focus of GS research for crop plants is on improving methods, broadening the scope of application, and investigating new avenues for understanding the genetic basis of characteristics. Genomics selection (GS) hasGenomic selection (GS) a wide range of uses, from addressing climate changeClimate change to accelerating breeding cycles. A viable path forward for sustainable agriculture in the face of changing climatic conditions is provided by the possibility for GS to aid in the development of climate-resilient crops. This chapter will essentially explore the many facets of genomic selection (GS), including its statistical support, current status in crop plant research, and potential future role in developing resilient crops.
