Three hundred and sixty-nine F2 individuals produced from Northeast Agricultural University Resource Population (NEAURP) were genotyped by 23 fluorescent microsatellite markers on chromosome 1. The characterization of these microsatellites was moderate or high polymorphic except marker MCW0058 which was low polymorphic. The length of the sex averaged linkage map was 637.9 cM. The order of MCW0115 and ROS0025 disagreed with that of EL map, but consisted with that of W map. The intervals of markers were larger than those of three reference families.
