Noodle Quality Evaluation of New Wheat Cultivars from Northern China Winter Wheat Regions
摘要
Abstract
Fifty-two cultivars and lines from Northern China Winter Wheat Regions, and six cultivars from Australia and America were planted in two locations in two years to evaluate their milling quality, Mixograph and Mixolab parameters, pasting properties and noodle quality. Five gene-specific markers were used to test their effects on quality traits. The results indicated that most of the tested cultivars were featured with hard grain and strong gluten. Large variations of flour yield, flour a* value, b* value, yel-low pigment content, PPO activity, Mixograph parameters, Mixolab parameters such as development time and stability were ob-served. The Mixograph parameter width at 8 min and Mixolab parameter stability were important for predicting noodle quality, accounting for 36.9% and 28.0% of the variation for noodle total score, respectively.Ppo-A1aandPpo-A1bgenotypes had the frequency of 41.4% and 58.6%, respectively, with significant difference in (P< 0.05) PPO activity. The frequency ofPpo-D1a and Ppo-D1bwas 51.7% and 48.3%, respectively, and there was no significant difference in PPO activity between two genotypes. The frequency ofPsy-A1a andPsy-A1b was 81.0% and 19.0%, respectively, and the yellow pigment contents of two genotypes were significantly different (P< 0.05). The 1BL/1RSand non-1BL/1RScultivars had the frequency of 13.8% and 86.2%, respectively, with significant difference (P< 0.05) in flour L* value, yellow pigment content, Mixgraph parameters such as right of peak slope and width at 8 min, and Mixolab parameter stability. Four cultivars including Zhoumai 26, Zhongmai 895, Sunzell, and CA1004 showed excellent noodle quality. This study provides important informations for wheat breeding and cultivar extension.关键词
