Abstract：In order to define the present status and progress of wheat quality breeding in Shandong Prov-ince in recent years,the quality characters of 306 new lines were determined in Shandong wheat regional test in 2008 ~2014.The grain quality,protein content,milling quality,farinograph parameters were determined and analyzed.The results showed that the average unit weight of 806 g/L,the hardness index was 66,the grain crude protein content of 14.0%,wet gluten content of flour 35.9%,sedimentation value and 32.5 mL, the water absorbing capacity of flour was 62 mL/100 g,the dough stability time was 3.8 min,the flour yield was 70.6%,and the whiteness of 75.6.The bulk density,hardness index,crude protein content,wet gluten content,water absorbing capacity overall level of new lines were higher;the sedimentation value was seconda-ry;the flour yield and stable time were lower;the flour whiteness was poor.Only four lines had higher com-prehensive quality characters which reached the national standard of strong gluten wheat but not the weak glu-ten wheat.The poor milling quality and the short dough stability time were the main problems of the new wheat lines in Shandong wheat regions test.
