Random Amplified Polymorphic DNA Analysis of Germplasm Resources of Exocarpium Citri Grandis / 广州中医药大学学报

ABSTRACT

Objective To investigate the influence of producing areas and sexual reproduction on the genetic features of Citrus grandis‘Tomentosa’. Methods The genetic distance in different species was counted,and the DNA fingerprint of germplasm resources of Citrus grandis ‘Tomentosa’ was established after random amplified polymorphic DNA analysis of Citrus grandis ‘Tomentosa’ and Citrus grandis (L.) Osbeck of various species from different producing areas. Results The genetic distance index D of Citrus grandis ‘Tomentosa’ and Citrus grandis (L.) Osbeck of various species from different producing areas was in the range of 0.01~0.64. Conclusion Sexual reproduction and the changes of producing areas can result in the genetic diversity of Citrus grandis ‘Tomentosa’.
