Abstract: The polyphenol oxidase ( PPO) is a major factor to cause an undesirable brown discoloration of wheat-based end products during processing or storage. A double haploid (DH) population with 71 lines derived from Zhongyou 9507 with higher PPO activity and CA9632 with lower PPO activity. Field trails we
