基于SSR标记对茶树紫阳群体种种质资源的遗传多样性研究
Genetic Diversity of Camellia sinensis Ziyang Population Germplasm Resources Based on SSR Markers
摘要
Abstract
Thirty Camellia sinensis Ziyang germplasm resources and 9 Camellia sinensis cultivars were used to analyze the genetic diversity based on 25 pairs of SSR markers.A total of 236 stable and clear bands were amplified,with an average of 9.44 bands per one marker.Among them,225 bands were polymorphic,with a polymorphism rate of 95.34%.The genetic distance of Camellia sinensis Ziyang populations were 0.195～0.736,with an average genetic distance of 0.591.The genetic distance between ZY01 and ZY18 was the largest(0.736),with the farthest genetic relationship.The genetic distance between ZY10 and ZY12 was the smallest(0.195),with the closest genetic relationship.When the genetic distance was 0.640,39 tea tree materials could be clustered into 13 categories,of which 30 Camellia sinensis Ziyang population germplasm resources were clustered into 10 categories.The results indicated that the genetic diversity of Camellia sinensis Ziyang population germplasm resources was higher.关键词
