Seed storability (SS), also called seed longevity, is a valuable trait for seed banks and providing reliable crop seeds to farmers, which is usually negatively correlated to lipoxygenase (LOX) activity. In this study, the seed storability of 60 accessions of CIMMYT core wheat germplasm panel (CIMCOG) was investigated through artificial aging (AA) test, including three parameters relative germination potential (RGP), relative germination rate (RGR) and relative seedling vigor index (RVI). Significant positive relationships were observed among RGP, RGR and RVI. And the genotypes at three LOX activity related QTLs/genes QLpx.caas-4B, QLpx.caas-1AL and TaLOX-B1 were also identified with published trait-associated molecular markers. For QLpx.caas-4B, a total of five alleles were detected at the locus of Xgwm251, and one marker-trait association was identified for RVI. Four and two alleles were detected at the loci of QLpx.caas-1AL and TaLoxB1 that were significantly associated with RGP, RGR and RVI, respectively. A total of 9 haplotypes were detected at three lipoxygenase activity related gene loci, and the haplotype of three lipoxygenase loci showed a significant association with RGP, RGR and RVI. The haplotype of Xgwm251-125bp+ Xwmc312-247bp + TaLox-B1b produced seeds with the best storability in the CIMCOG, which could benefit the breeding for wheat with good seed storability.
