摘要
[Objective] This study aimed to analyze the quantitative trait loci （QTLs） of grain storage durability for maize under controlled deterioration conditions by using SSR markers. [Method] The recombinant inbred line population F 2 derived from the cross of shen 137/02-50 was used to do the simple sequence repeats （SSRs） and QTL analysis. [Result] The 2 parents showed good polymorphisms. Three loci were detected on chromosome 1, chromosome 6 and chromosome 9, accounting for 41.2% of total phenotypic. [Conclusion] This study provided theoretical basis for using molecular marker to assist the breeding of storage durable maize varieties.
[目的]通过SSR标记分析人工老化条件下玉米耐储藏性QTL。[方法]利用沈137和02-50组合衍生的重组自交系群体(F2)对人工加速老化的玉米种子进行发芽试验及耐储藏性QTL分析。[结果]两亲本具有多态性,在第1、6、9染色体上检测到3个耐储藏QTL,能解析总表型变异的41.2%。[结论]为分子标记辅助选择耐储藏玉米品种提供一定的理论基础。
