Common buckwheat ( F. esculentum ) is an allogamy crop, which is heterogony. There is heterogeneity in the species. To reveal the genetic diversity within cultivar population, In order to explore the sampling strategy that can reveal genetic diversity of buckwheat resources on the molecular level. PCR with intron-splice junction primers and long random primers was employed to reveal the genetic diversity within nine common buckwheat varieties and one tartary buckwheat cultivar population among different individuals. We established the sampling strategy in its genetic diversity study. Then we used the established sampling strategy, and the same PCR markers technique,to analysis the genetic diversity of 86 common buckwheat resources, the main results are as follows

2 STR-PCR We analysed the results of STR with the silver dye in the beginning. The silver dye of STR analysis on a sporadic DMD family shows the band confirmation is subjective by eyeballing. It can not detect the small repeats and the size of polymorphic fragments. For limitation of the silver dye, we analysed the band size of STR with the SAGAGT Genotyping System. Primer are designed according to the nucleotide sequence of five STR markers (located in 5' terminus and intron 44, 45, 49, 50) of dystrophin gene. The 5' end of the forward primer are attached a M13 tailed primer which conjugated to the infrared flourescent dye.
