Genetic Diversity in Naked Oat (Avena nuda) Germplasm Revealed by AFLP Markers
用20对AFLP引物组合对281份栽培裸燕麦(Avena nuda)进行遗传多样性分析,共得到1137条带,其中260条为多态性带,引物的平均多态性百分率为22.96%,平均多样性信息指数(PIC)为0.0326.以地理来源分组,不同来源的组群Simpson指数在1.235～1.495之间,Shannon指数范围为0.1558～0.4437,组群内变异贡献率为83.45%,组群间变异占16.55%.组群大小与多态性位点数、组群内变异贡献率、Sim…查看全部>>
Oat (Avena L.) is one of the most important cereal crops in the world, ranked at the sixth top place in planting area and yield among all cereal crops, and possesses high values in food and nutrition, health protection and feeding livestock. Naked oat (A. Nuda) is an endemic type in China. However, a few studies on naked oat germplasm at molecular level have been reported. The aim of this study was to evaluate the genetic diversity of core collection of nake…查看全部>>
