以10个不同遗传背景的单倍体诱导系为共同父本,24个人工组配的不同基因型基础材料为受体母本,对基础材料、基础材料的杂交模式和基础材料的组配亲本的单倍体诱导率进行分析。结果表明,不同基因型基础材料间单倍体诱导率差异显著,变化幅度较大,诱导系诱导效率与基础材料基因型有一定的相关性;相同杂交模式的基础材料间诱导率变化也较大,杂交模式间诱导率均值差异不显著;具有相同亲本的基础材料诱导率变化较大,组间差异不显著。诱导率大小受基因互作等多因素影响。
The haploid inbred lines of 10 different genetic backgrounds were the common paternal mothers. The 24 different genotypes with the same artificial parent were used as the recipient maternal parent. The hybrids of the basic materials, the basic materials and the parents of the basic materials The haploid induction rate was analyzed. The results showed that there was a significant difference in the haploid induction rates among different genotypes, and the variation range was large. The induction efficiency of the induction lines was related to the genotypes of the basic materials. The change of the induction rate between the basic materials of the same hybridization patterns was also larger , There was no significant difference in the average induction rate between hybridization patterns. The induction rate of the basic materials with the same parental changes was larger, but the difference between the two groups was not significant. Induce the size of the gene interaction and other factors.
