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

heterogony：世代交替

二次世代交替可分為真正世代交替(metagenesis)又爽又大、異型世代交替(heterogony)、變型世代交替(alloiogenesis)等. 世代交替明顯地受環(huán)境因素的影響,這可以在種種生物實(shí)驗(yàn)上表現(xiàn)出來.
