运用主基因-多基因混合遗传模型理论,对构建的玉米常规自交系与单倍体诱导系杂交组合群体A(四-287×Y11)和两个单倍体诱导系杂交组合群体B(Y6×Y11)的F₂世代的单倍体诱导性状的遗传进行研究。结果表明,群体A的单倍体诱导性状遗传由两个主基因控制,表现加性-显性效应,遗传率达91.27%;群体B检测到1个主基因,表现加性-显性效应,遗传率为38.86%,群体B的诱导率遗传主要由主基因和多个微效基因共同作用。

Two F₂ generations of maize haploid induction lines population A (Si-287×Y11) and population B (Y6×Y11) were used to study the inheritance of maize haploid induction with major gene+ploy gene mixed inheritance analysis. The results showed that the inheritance of haploid induction was controlled by two major genes in population A. The gene action was mainly additive to partial dominance and heritability was 91.27%. A gene with additive to partial dominance effect accounting for 38.86% of the phenotypic variation was identified in population B. It indicated that the trait was controlled by major gene and poly small genes.
