摘　　要：为进一步了解小麦生物强化育种的可行性,以山农483×川35050杂交衍生的小麦重组自交系(RIL)群体的131个株系(QM1~QM131)及其亲本为材料,连续2年在泰安和菏泽两地种植。测定该RIL群体籽粒镁、磷、硫、钾、钙等常量元素及锰、铁、铜、锌等微量元素的含量,分析了其变异系数、遗传力、相关性及环境对微量元素含量的影响。结果表明,供试材料中各被测元素的变异系数范围为7.9%~32.7%,遗传力的变化范围为29.58%~56.34%;常量元素中,镁和磷间的相关性较大,相关系数为0.440;微量元素中,锰和铜间的相关性较大,相关系数为0.454;环境对小麦微量元素含量有明显影响。高铁元素含量株系QM103、高锌元素含量株系QM105可作为育种材料。In order to further understand the feasibility of bio-fortification breeding of wheat, 131 re- combinant inbred lines（RILs）（QM1-QM131） derived from a cross between Shannong 483 and Chuan 35050 were grown in the experiment stations of the academy of Tai^an and Heze agriculture Science in 2007--2009 wheat season,and the concentration of major mineral elements in grain,including macro- nutrients Mg, P, S, K and Ca, and micronutrients Mn, Fe, Cu, and Zn, were evaluated. The coefficients of variation,hereditary and correlation coefficients were calculated, and the effects of different loca- tions on micronutrient concentration were also analyzed. Experimental results showed that the varia- tion coefficients ranged from 7.9% to 32.7% ,and the heritability ranged from 29.58% to 56.34%. Among the macronutrients,positive correlations between the concentration of Mg and P（r= 0. 440） was highest, and among the micronutrients, positive correlations between the concentration of Mn and Cu （r=0. 454） was highest. The differences in the micronutrient concentration between the two loca- tions were obvious. The high Fe concentration line QM103 and high Zn concentration line QM105were selected and could be used as the breeding materials.
