| In order to further understand the feasibility of bio-fortification breeding of wheat,131 recombinant 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 macronutrients 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 locations on micronutrient concentration were also analyzed. Experimental results showed that the variation 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 locations were obvious. The high Fe concentration line QM103 and high Zn concentration line QM105 were selected and could be used as the breeding materials. |
