Abstract:: Taking 12 mango germplasms as metarials，SRAP marker was used to analyze genetic diversities.The results showed that 22 primers selected from 36 SRAP-primer were used for amplification and 251 DNA bands were obtained,including 181 polymorphic bands.Each primer amplified 15.08 polymorphic bands.The percent of polymorphic was 72.11%.Based on UPGMA analysis,all samples showed higher similarities and teir coefficients from 0.77 to 0.89.If the coefficient 0.78 was regarded as divided line of their genetic relationship,12 materials could be clustered into 3 groups by SRAP.The study indicated that the genetic relationship of mango cultivars or lines could be better assessed by SRAP which could be used in mango germplasms identification.
