Abstract:
The natural population Kingdonia uniflora Balf.F.et W.W.Smith were used as test materials,by using SCoT markers,was studied to estimate genetic diversity of the natural population Kingdonia uniflora Balf.F.et W.W.Smith,aiming at providing molecular biological basis for the evaluation and protection of the germplasm resources of Kingdonia uniflora Balf.F.et W.W.Smith.The results indicated that selected 20 reproducible and clear bands from 30 primers were amplified by PCR,a total of 99 bands were amplified by 20 primers,including 72 polymorphic bands,and the polymorphic rate was 72.73%.The observed number of alleles in 36 materials was from 1.333 3 to 2.000 0,with an average of 1.724 5.The effective number of alleles was from 1.219 8 to 1.806 3,with an average of 1.533 1;Nei′s gene diversity was from 0.132 5 to 0.439 0,with an average of 0.297 7.Shannon information index was from 0.195 6 to 0.628 9,with an average of 0.432 4.The cluster analysis showed that the genetic similarity coefficient of 36 Kingdonia uniflora Balf.F.et W.W.Smith germplasm resources was from 0.650 0 to 0.949 0,with an average of 0.757 7.The Kingdonia uniflora Balf.F.et W.W.Smith germplasm resources of the neighbouring or similar identifier were clustered in a categorie or subclass.This indicated that genetic diversity of Kingdonia uniflora Balf.F.et W.W.Smith germplasm could be revealed by SCoT markers.
