茶树DNA分子指纹图谱研究进展

摘要

Molecular fingerprintings revealthe differencesbetweenindividualsatDNA level directly, which can identify tea cultivars effectively and protect the right of the varietyplant. In this paper, the classification, concept and characteristics of fingerprintingwere described.The research progressincluded 7technologies fortea plant fingerprinting,as well as the application of fingerprinting in tea germplasm resources and breedinginvestigation were introduced.The problems existed in fingerprinting researchoftea plantwerediscussed,and the construct of standard fingerpinting of tea cultivarswasproposed.%分子指纹图谱直接反映生物个体在DNA水平上的差异，可有效鉴别茶树品种，保护品种权。本文概述了指纹图谱的分类、概念和特点，近年来国内外7种分子指纹图谱方法在茶树中的研究进展，以及指纹图谱在茶树种质资源与育种研究中的应用，探讨了我国茶树分子指纹图谱研究中存在的一些问题，并由此提出构建茶树标准指纹图谱的设想。
