Abstract:
Taking 95 peach cultivars as materials, the genetic diversity of peach varieties using 32 pairs of SSR molecular markers were analyzed.The results showed that 93 bands were amplified by 18 informative and reliable primers,of which 50 bands were polymorphic loci.A relatively low level of genetic diversity (Nei’s gene diversity 0.5652 and Shannon index 1.1125) was revealed at population level.For peach maturity,the experimental results for genetic analysis had been taken,and the precocious and medium groups had similar genetic data had been found.In the same way,that the late maturity varieties had more distant relationship with both could be speculaten.The mature differentiation of peach associated with allele frequency could be taken,this would help for the future indepth study genetic analysis of peach.
