Abstract: 【Objective】 To clarify the present situation of wheat processing quality in Sichuan province and provide key information for quality breeding. 【Method】 Seven wheat cultivars with different levels of gluten strength were planted in 18 ecological sites that can represent the current wheat producing regions in Sichuan province, in three consecutive wheat growing seasons. The harvested wheat samples were carefully cleaned and stored at room temperature before measuring processing quality parameters.【Result】 The processing quality parameters of the most harvested samples met the national standard for weak-gluten wheat, although these parameters varied among ecological sites, growing seasons and cultivars. When analyzing the data of each ecological site separately, we found that most areas of wheat producing regions in Sichuan (especially Chengdu Plain and north Sichuan) were suitable for the production of weak-gluten wheat. Notably, the samples of elite cultivars shown better weak-gluten quality, compared with those of other cultivars. Analysis of variance (ANOVA) indicated that the effects of cultivars, growing seasons and ecological sites on processing quality ranked as growing seasons>cultivars>ecological sites, under our experimental conditions, which further indicated that Sichuan is suitable for producing of weak-gluten wheat. To evaluate the end-use quality of the harvested wheat samples, the flour was used to make crisp cookies, and 20 brands of popular commercial cookie flour in the supermarket were used as control. With the exception of the cultivar "Shumai969", the flour of other 6 cultivars exhibited better cookie-making quality than control. When considering the difference in ecological sites, the flour in 17 of the 18 sites (except Zizhong County in Neijiang) shown better cookie-making quality than control. 【Conclusion】 The wheat planting region in Sichuan is one of the best place in China to produce high quality weak-gluten wheat, and the growing of elite cultivars in favourable areas is more conducive to the play of ecological advantages of Sichuan.
