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

Aiming at the high-speed matching controlling problems between adaptive filters inplemented by FPGA and the high-speed AD converters, a high-speed sampling and adaptive filtering system was designedusing asynchronous FIFO. The dual channels AD converter AD9238-40 was used as input stage, two asynchronous FIFOs on-chip were used as high-speed buffer memory, and the sampling and adaptive filtering was controlled by FPGA. The asynchronous FIFO was customized and simulated on Quartus II, the sampling and adaptive filtering controller was designed and also simulated on Quartus II. The high-speed matching controlling of the dual channels AD converter AD9238-40 and the adaptive filter was implemented.
