以米粒中微量元素铁、锌、锰含量各具差异的７个特种稻品种配制完全双列杂交，利用Ｇｒｉｆｆｉｎｇ方法１模型Ⅰ分析３种微量元素含量的配合力；利用变异系数分析法研究７个亲本在不同地点、不同年份间微量元素含量的稳定性。结果表明，铁、锌、锰３种微量元素的一般配合力（ＧＣＡ）方差和特殊配合力（ＳＣＡ）方差均达极显著水平，其中铁含量的ＳＣＡ方差大于ＧＣＡ方差，锌、锰含量ＧＣＡ方差大于ＳＣＡ方差，说明这３种元素同时受加性和非加性基因作用，铁含量以非加性效应为主，锌和锰含量则以加性效应为主。同一亲本３种元素间ＧＣＡ效应差异较大，同一元素不同亲本间差异亦较大；同一元素不同组合间ＳＣＡ表现较大变幅，并有ＧＣＡ效应高的亲本其杂交组合的ＳＣＡ效应多数表现较高的趋势，但亦有ＧＣＡ低的亲本间杂交出现ＳＣＡ高的组合。变异系数分析结果显示，７个亲本在不同年份、不同地点间，各元素含量的差异较大，表明稻米中铁、锌、锰含量除受遗传控制外，还明显受环境条件的影响，并表现基因型×环境互作。
Seven special rice cultivars with different contents of trace elements iron, zinc and manganese in rice grain were prepared for complete double-line hybridization. The combining ability of three kinds of trace element contents was analyzed by Griffing method 1 model Ⅰ. The coefficient of variation The stability of trace elements in the parents at different locations and years. The results showed that the variance of GCA and SCA of three trace elements of iron, zinc and manganese reached extremely significant levels. The variance of SCA of iron content was greater than that of GCA, the variance of GCA of zinc and manganese content Is greater than the SCA variance, indicating that these three elements are affected by both additive and non-additive genes, with non-additive effect on iron content and additive effect on zinc and manganese content. There were significant differences in GCA effects among the three elements of the same parent, and significant differences among parents of the same element. SCA in different combinations of the same element showed a larger amplitude, and most of the SCA effects in hybrid combinations of parents with GCA effect were mostly High trend, but there are also low GCA hybrids appear low SCA high combination. The coefficient of variation analysis showed that there were significant differences among the seven parents in different years and locations, indicating that the contents of iron, zinc and manganese in rice were significantly affected by environmental conditions and gene expression Type × environment interaction.
