Of total 24 cpSSR primer pairs screened,only four presented length polymorphism in the populations of C.mollissima tested.In order to estimate genetic variation and genetic structure of the Chinese chestnut,we surveyed nine populations around China with cpSSR markers.Of all the haplotypes found in the wild Chinese chestnut,only two variants appeared in all the local varieties.In the Chinese chestnut,average number of alleles(A) and effective number of alleles(N_e) are 3 and 1.635,respectively.PIC is 0.326 a...
