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.
