Abstract: To study the influences of different sowing dates on the yield and quality of strong gluten wheat, taking‘Yumai 34’strong gluten wheat in the Yellow River area as experimental object, three completely randomized block design experiments were conducted at sowing dates (Oct. 8th, Oct. 18th and Oct. 28th), and parameters such as yield, yield factors, protein content and its components, starch content and its components, and farinograph values were measured. Results showed that during Oct 8th to 28th, early sowing could improve yield (the highest yield was 3593.33 kg/hm², the lowest yield was 1862.25 kg/hm²). When sowing date was postponed, grain protein content increased significantly, starch content decreased, and the effect of sowing date on protein components and starch components was inconsistent. Taking into consideration of flour quality, overall assessment indicates that mid-time (Oct 18th) sowing was the best, and late-time (Oct. 28th) sowing performs the worst.
