Abstract
Objective] The aim was to investigate the genetic diversity of Magnolia officinalisfrom different provenances,families and individu-als, provide a theoretical basis for breeding.[ Method] Amplified fragment length polymorphism( AFLP) was used to evaluate the genetic di-versity of Magnolia officinalis from Hubei, Guangxi and Zhejiang among different provenances, families, individuals.[ Result] The genetic dis-tance between the 3 provenances was 0.048 2-0.128 4, and the similarity between Guangxi and Zhejiang was higher than Hubei.The aver-age level of population genetic diversity, total population gene diversity, gene flow were 0.203 5, 0.254 1, 3.421 7.The average number of observed alleles and effective alleles were 1.658 3 and 1.341 4; Nei’s and Shannon diversity index were 0.203 5 and 0.308 7.The genetic diversity level of Hubei was the highest (0.225 8), Zhejiang Jingning was the lowest (0.173 9).The genetic diversity in families were 0.264 4, 0.181 9 and 0.173 8, Shannon diversity index was 0.415 4.[Conclusion]The genetic diversity of Hubei Wufeng was the highest, and so was the genetic diversity among individuals.The diversity index and information index among different provenances were close which in-dicate that the variation level of the different species in families was similar in the respective ecological environment.It should be payed full at-tention to the selection of superior provenances,families and superior individuals in the process of breeding of Magnolia officinalis.关键词
