Advances in Genome-Wide Association Study Associated Important Traits in Apple
This paper briefly introduces the basic principles,analysis processes,and advantages of genome-wide association study(GWAS),and focuses on the new progress in the identification of genes related to important traits such as apple phenological period,appearance and internal quality,and resistance to biotic and abiotic stresses in apple.The limitations and prospects of the current research were put forward in order to provide a theoretical basis and reference for breeding breakthrough cultivars of apples.
