Abstract
A boost in the crop improvement rate is essential for accomplishing a sustainable food supply and other demands of rapid population growth. Genomic selection (GS), a very promising breeding strategy used effectively in animal breeding, is now used in crop improvement. GS offers a reduced duration of breeding cycles by rapidly selecting better genotypes. Several empirical and simulated research on GS and their implications on agricultural production enhancement have lately been published. We briefly discuss the GS methodology, its present position, the GS advantages over alternative methods of breeding, commonly used prediction models of GS, and factors interfering with the prediction accuracy of GS to provide a comprehensive grasp of the technology. In addition, the integration of speed breeding and other modern techniques for increasing the effectiveness and speed of GS are discussed.
