Genome-wide association studies reveal novel loci controlling tuber flesh color and oxidative browning in Dioscorea alata.

Background: Consumers' preferences for food crops are guided by quality attributes. This study aimed at deciphering the genetic basis of quality traits, especially tuber flesh color (FC) and oxidative browning (OB) in Dioscorea alata, based on the genome-wide association studies (GWAS) approach. The D.
