[Objective] This study aimed to map quantitative tarit loci (QTLs) associated with salt tolerance of maize inbred line at seedling stage. [Method] The recombinant inbred line (RIL) F7 including 171 plants were developed by single seed descent procedure from a combination, Huangzaosi×Mo17, and used to map QTLs associated with salt tolerance, based on the constructed genetic map of SSR markers. [Result]A linkage map consisting of 81 SSR markers loci from 10 chromosomes (1 428.3 cM in total length, with an average distance of 17.63 cM between two neighbouring loci) was constructed. Six QTLs associated significantly with salt tolerance were detected at chromosomes 1, 5 and 6. [Conclusion] This study is extremely significant for better understanding salt tolerance-related genes, the genes’ location and cloning, salt tolerance mechanism and the marker-assisted selection of salt tolerant maize.
