| Abstract: | Genetic differences of 7 accessions of Stylosanthes Swartz germplasm were studied using the isozymatic electrophoresis technique. The result showed that there were certain differences in the number and locus of the esterase(EST) and superoxide dismutase(SOD) isozyme bands among the accessions. The difference of esterase(EST) isozyme in zymograms phenotypes was an important genetic marker at protein level to identify the 7 accessions. According to the genetic distance, the 7 accessions were divided into 4 groups. S. guianensis cv. Reyan 13, S. guianensis cv. Reyan 5 and S. guianensis cv. Mineirao were in the first group. S. hippocmpoides was in the second group. S. hamata cv. Verano and S. scabra cv. Seca were in the third group. S. seabrana was in the forth group. |
