| 摘 要： | 锈病是影响花生产量和品质的主要真菌性病害。本研究以“中花10号× ICG 12625”构建的重组自交系群体（RIL）为材料，在武昌和阳逻两个环境中对其F8群体进行锈病抗性鉴定，获得了8份抗锈病材料（QT0348、QT0368、QT0400、QT0402、QT0419、QT0458、QT0463和QT0485）。利用前期构建的遗传图谱进行QTL分析，检测到10个与锈病抗性相关的QTL，贡献率为4.54%~10.78%，分布于7条染色体上。其中，qBB06.1和qBB06.4为重复一致的QTL，贡献率为10.76%。根据侧翼标记在物理图谱进行比对，发现对应区段含有193个基因，其中178个基因被注释，功能注释基因中有1个NBS-R基因。本研究结果为花生抗锈病的遗传改良奠定了基础。

| Abstract: | Rust is a major fungal disease affecting peanut yield and quality. In this study, a recombinant inbred line population （RIL） constructed from “Zhonghua 10 × ICG 12625” was used as material. The F8 generation population was tested for rust resistance in two environments, Wuchang and Yangluo. 8 rust-resistant lines （QT0348, QT0368, QT0400, QT0402, QT0419, QT0458, QT0463 and QT0485） were obtained. QTL analysis using the pre-constructed genetic map detected 10 QTLs associated with rust resistance, with 4.54% - 10.78% phenotypic variation explained （PVE）, distributed on 7 chromosomes. Among them, qBB06.1 and qBB06.4 were repeat consistent QTLs with contribution rates of 10.76%. The corresponding segment in the physical map contained 193 genes according to the flanking markers, of which 178 genes were annotated, and one NBS-R gene was among the functionally annotated genes. The results of this study provide a basis for genetic improvement of rust resistance in peanut. |
