| Abstract: | 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. |
