| Abstract: | F2:10 RIL population with 154 lines, crossed by Charleston as female parent and Dongnong 594 as male parent were used.164 SSR primers were screened with the two parents and amplified on the 154 lines. A new soybean molecular genetics map, named NEAUSRI-GMS, was constructed by Mapmaker. The total length of the soybean genetic map is 1 913.5 cM,and the average distance among markers is 11.89 cM. The length of linkage group varied from 0.4 to 309.5 cM, and the markers on the linkage group varied from 2 to 28. The distribution of SSR markers on every linkage group is not even. High density region of markers existed on linkage group Al, C2, and Dla. Compared with 5 soybean genetic maps constructed at home and abroad, NEAUSRI-GMS has high homologous with the public genetic map abroad. |
