Quality characteristics (moisture, protein, ash, bulk density, falling number, damaged kernel, and foreign material) of 443 domestic wheat samples harvested between 2011 and 2013 were compared with those of 160 imported wheat samples from the United States, Australia, and Canada. Moisture content of domestic wheat (10.9~13.9%) was generally higher than that of imported wheat (8.0~12.6%). Large variation in protein content was found in domestic wheat compared to imported wheat even though variation in protein content of domestic wheat tended to decrease every year, implying quality control efforts for domestic wheat. A similar trend was observed in ash content, which was approximately 0.1% higher in domestic wheat kernels over 3 years. Imported wheat samples had a falling number of 300 or above. On the other hand, some domestic wheat samples had a falling number of 300, which meant low quality of wheat kernels. Generally, quality variations in domestic wheat kernels decreased over the years; however, it is necessary to maintain minimum requirements of moisture content and falling number for high and consistent quality domestic wheat.
