山东保存小麦种质资源面粉白度分析
对2068份小麦种质资源进行了面粉白度测定和高白度小麦种质子粒硬度测定。结果表明,山东小麦地方品种、山东小麦育成品种和省外引进小麦品种面粉白度值的分布范围分别为63.9～82.9、63.1～83.8和67.2～84.2。筛选出面粉白度值大于80的小麦种质342份（包括白度值大于83的种质26份）,其中地方品种22份,山东育成品种（系）228份,省外引进种质92份。从高白度小麦种质资源中,筛选出子粒硬度指数≥50符合高白度强筋、中强筋或中筋的种质资源18份,对培育中筋以上高白度小麦新品种,以满足人们口味和健康保障具有重要意义。...

| Bibliography: | The flour whiteness of 2068 wheat landraces and varieties or breeding lines was investigated,and the grain hardness index of wheat germplasm with flour whiteness value over 80 was measured.The results showed that the ranges of distribution in flour whiteness values for Shandong landraces,Shandong varieties or lines,and varieties or lines collected from other provinces were 63.9-82.9,63.1-83.8 and 67.2-84.2,respectively.Three hundred and forty-two varieties or lines with the flour whiteness values over 80 were identified,which included 22 landraces,228 Shandong varieties or lines,and 92 varieties or lines from other provinces.Among them,26 landraces and varieties or lines had flour whiteness values over 83,and 18 landraces and varieties or lines displayed high grain hardness index（≥50）.These 18 high grain hardness landraces and varieties or lines are importance in developing high-flour-whiteness and strong-medium gluten wheat variety to meet people＇s taste and health security.
