Quality Character Analysis of Wheat Lines in Shandong Regional Tests in Recent Six Years
摘要
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.关键词
