Yu W.H., and Cheng Q.T., 2024, Accelerating yam breeding cycles with genomic selection, Genomics and Applied Biology, 15(6): 319-331 (doi: 10.5376/gab.2024.15.0033)

This study evaluates the potential of genomic selection (GS) in yam breeding, particularly its advantages in shortening breeding cycles and enhancing the selection efficiency of key agronomic traits. Traditional yam breeding is constrained by long generation times and complex genetic structures. By utilizing genomic data, GS can significantly accelerate generation turnover and increase genetic gain. This study discusses the role of integrating GS with speed breeding in yam breeding, as well as the advantages of GS in managing the complexity of genotype-by-environment (GxE) interactions. In addition, the development and optimization of genomic resources and their potential applications in yam breeding are explored. The application of GS not only improves breeding efficiency but also has a positive impact on the quality and productivity of yam varieties, providing new approaches to enhance global food security.
