Objective To understand the quality status of the harvested wheat in 2014 in Jiangsu Province. Methods Totally 917 samples which covering all the grain-producing county in the entire province were selected as test samples, the test weight, unsound kernels, foreign matter, moisture content, the color, and odour of the wheat were inspected according to GB 1351-2008“wheat”. The test weight, moisture content of the wheat were determined by the GB/T 5498-2013 and GB/T 5497-1985. The foreign matter and unsound kernels were determined by GB/T 5494-2008. The color and odour of the wheat were identified by the GB/T 5492-2008. Results The quality of the harvested wheat in 2014 in 13 cities 62 districts of Jiangsu Province was investigated and compared with those in recent five years. The results showed that the proportion of wheat which was generally above the average was 96.3%. The average test weight of wheat was 771 g/L, increased 10 g/L by the last two years. The average moisture content of wheat was 12.5%, which was smallest in recent five years. The average content of foreign matter was 0.9%, which had little changed in recent five years. The unsound kernel content of wheat was 5.0%, which was smallest in recent three years. Moreover, all samples had the normal color and odour of wheat. Conclusion The overall quality of wheat in 2014 in Jiangsu Province was better than the last years, especially the harvested wheat in Xuzhou and Suqian cities had good qualities.
