No full textPolyphenol oxidase (PPO) activity is a major cause of undesirable brown color of semolina. In tetraploid wheat, the Ppo-A1 gene is significantly involved in the phenotypic expression of PPO activity. The main goal of this study was to develop and validate a more efficient marker for Ppo-A1 to facilitate marker-assisted selection for low PPO activity in tetraploid wheat breeding programs. A large tetraploid wheat collection, including durum cultivars, domesticated and wild accessions, was used to evaluate the PPO activity. The heritability values indicated that the phenotypic expression of PPO activity was mainly due to genotypic effect. PPO18, and a new marker named MG18, were used to study the Ppo-A1 allelic variation in a tetraploid wheat collection. PPO18 analysis detected four alleles (Ppo-A1b, Ppo-A1e, Ppo-A1f and Ppo-A1g). The high frequency of Ppo-A1g (no PCR product) detected in the tetraploid wheat collection, led to the development of a new genome-specific Ppo-A1 marker (MG18). MG18 analysis identified the same alleles as PPO18 which were associated with low or high PPO activity. The new MG18 marker was more efficient than PPO18 in detecting the four different alleles of Ppo-A1 in the tetraploid wheat collection. Indeed, the accessions assigned to the Ppo-A1g group, according to PPO18, when tested with MG18, were better classified in the four alleles of the Ppo-A1 gene. The MG18 analysis proved that the PPO18 marker overestimated the number of accessions with Ppo-A1g. Therefore, MG18 can be applied to large-scale marker-assisted selection for PPO activity in durum breeding programs
