[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.展开更多
