1986年始,以奥帕克玉米的软硬胚乳相近基因型为材料,在与种子幼胚相同的世代上以单粒胚乳分析为基础,采用莫惠栋3N 胚乳模型探讨胚乳硬质度、胚乳赖氨酸含量及胚乳蛋白质含量的遗传规律。结果表明:奥帕克-2(opaque-2)主基因的修饰基因属多基因系统·位点间上位性互作效应起重要作用。6～9对因子间互作被鉴别出来。比较了采用2N 模型分析3N 性状所带来的偏差。并对胚乳性状遗传特点与模型配合的有关问题作了简要讨论.
Starting from 1986, using the similar genotypes of Opaque maize as the material, based on single endosperm analysis in the same generation as the immature embryos, the model of endosperm hardness, endosperm lysine The Genetic Rule of Acid Content and Endosperm Protein Content. The results showed that the modified gene of opaque-2 gene plays an important role in the interaction between epistasis and epistasis in multiple gene systems and loci. 6 to 9 pairs of factors are identified between the interaction. The 2N model was used to analyze the bias of 3N traits. And the genetic characteristics of endosperm traits and the model with the related issues briefly discussed.
