Genetic Diversity of Armeniaca sibirica Germplasm Resources Revealed by SRAP Analysis
In this study,the genetic diversity of 25 Armeniaca sibirica clones were analyzed by using SRAP molecular markers.The results showed that 22 pairs of highly stable and polymorphic primer were selected from 100 pairs for amplifying bands of 25 A rmeniaca sibirica clones.The 564 bands were obtained,among which 443 bands were polymorphic bands accounting for 78.5％ polymorphism.The similarity coefficients were calculated by using NTSYS software based on SRAP results and ranged from 0.227 to 0.956.The 25 Armeniaca sibirica clones were divided into 8 groups at the similarity level of 0.685 and their genetic relationship became clear.The result might provide the theoretical date and technical reference for parents selection in A rmeniaca sibirica crossbreeding.
