摘要：

花生荚果、种子性状与产量紧密相关, 是重要的农艺性状。为挖掘与荚果、种子性状紧密连锁的分子标记, 本研究以大果品种冀花5号和小果美国资源M130组配衍生的315个家系RIL8群体为材料, 利用SSR、AhTE、SRAP和TRAP等标记构建了一张包含363个多态性位点的遗传连锁图谱。该图谱共包含21个连锁群, 总长为1360.38 cM, 标记间平均距离为3.75 cM。利用完备区间作图法对2017—2018年5个环境的荚果、种子相关性状进行数量性状基因座(quantitative trait locus, QTL)分析, 共鉴定到97个与荚果、种子性状相关的QTL, 可解释的表型变异为2.36%~12.15%, 分布在A02、A05、A08、A09、B02、B03、B04、B08和B09等9条染色体上。其中, 9个与荚果长相关, 13个与荚果宽相关, 14个与荚果厚相关, 11个与种子长相关, 14个与种子宽相关, 13个与种子厚相关, 13个与百果重相关, 10个与百仁重相关; 4个主效QTL分别为qPWA08.1、qPTA08.3、qPTA08.4和qSWB08.5, 可解释的表型变异分别为10.02%、11.06%、12.15%和11.97%; 45个稳定表达的QTL在3个以上环境可被重复检测; 连锁群A02、A08、B02、B04和B08上存在QTL聚集区。另外, 检测到15对上位性QTL, 可解释的表型变异为10.23%~51.84%。研究结果将为花生荚果、种子性状的分子标记辅助育种提供重要的理论依据。

Abstract:

Pod and seed traits are important agronomy traits, which are closely related to yield in cultivated peanut (Arachis hypogaea L.). In the present study, to identify molecular markers closely linked to pod and seed traits, a RIL8 population with 315 families was developed that derived from Jihua 5 with large pod and M130 with small pod of US germplasm. A genetic linkage map containing 363 polymorphic loci was constructed using SSR, AhTE, SRAP, and TRAP markers. All polymorphic loci were mapped on 21 linkage groups, which spanned 1360.38 cM with an average distance of 3.75 cM. Subsequently, a total of 97 QTLs for pod and seed traits were identified by ICIM method at five environments from 2017 to 2018, explaining the phenotypic variations of 2.36%-12.15%, and located on A02, A05, A08, A09, B02, B03, B04, B08, and B09 chromosomes. Among them, nine QTLs were detected for pod length, 13 QTLs for pod width, 14 QTLs for pod thickness, 11 QTLs for seed length, 13 QTLs for seed width, 13 QTLs for hundred-pod weight, 10 QTLs for hundred-seed weight. Four QTLs with major effect were detected, including qPWA08.1, qPTA08.3, qPTA08.4, and qSWB08.5, which explained the phenotypic variations of 10.02%-12.15%. Furthermore, 45 stable QTLs were repeatedly detected in more than three environments. QTL clusters were detected on A02, A08, B02, B04, and B08 chromosomes, respectively. In addition, 15 epistatic QTLs were identified that explaining phenotypic variation of 10.23%-51.84%. These results will provide an important theoretical basis for molecular marker-assisted breeding of pod and seed traits in peanut.
