山东小麦地方品种资源铁和锌含量分析

利用等离子体发射光谱仪,对426份山东小麦地方品种资源进行了铁和锌微量元素含量的测定,摸清了山东省小麦地方品种资源铁和锌含量的分布情况。结果表明,山东小麦地方品种资源铁含量的分布范围为5.2～44.1mg/kg,锌含量的分布范围为6.2～50.4mg/kg。铁含量最高的种质是土耳其和落麦,分别为44.1mg/kg和41.8mg/kg;锌含量最高的种质是大青芒,为50.4mg/kg。利用这些铁锌含量高、子粒商品性及面制品口味好的小麦地方品种作育种亲本,对培育子粒中富含铁锌微量元素的高营养小麦新种质,具有十分重要的意义。

Iron and Zinc Contents in Shandong Wheat Landrace

Wheat germplasm is a key factor in sustainable wheat breeding.In this study,the iron and zinc contents in flour of 426 Shandong wheat landraces were determined by inductively coupled plasma optical emission spectroscopy(ICP-OES).The results showed that the iron and zinc distribution ranges of Shandong wheat landraces are 5.2~44.1 and 6.2~50.4mg/kg,respectively,the landraces with the highest iron content 44.1mg/kg and 41.8mg/kg respectively are "Tuerqi" and "Luomai",and the landrace with the highest zinc content 50.4mg/kg is "Daqingmang".Using the selected wheat landraces with high iron and zinc contents also good grain and food quality as cross parents,it may be very important significance to breed new wheat varieties with high nutrient,and to investigate the genetic mechanism of iron and zinc accumulation in the grain.
