4.1. A scheme of molecular genetic map consisted of 20 linkage groups was constructed with the mapping software Mapmaker/EXP3.0 MapChart 2.0, which included 161 SSR markers. It covered approximately 1913.5cM of soybean genome with an average genetic distance of 11.89cM. The number of SSR markers on each linkage group varies from 2 to 28, with the length from 0.4cM to 309.5cM.
