Genetic Variances and DNA Fingerprints of 1 5 Teas in Fujian
摘要
Abstract
Identification and preservation of tea cultivars plays a crucial role in the production and development of thetea industry in China.This paper presents the genetic variances and molecular fingerprints of 1 0 tea cultivarsselected and cultivated by our research team and 5 control cultivars in Fuj ian by using SSR molecular markers.Itaimed to further clarify the genetic differences of these cultivars providing a basis for identification of newlyimproved tea cultivars and protection of intellectual property rights.In the course,6 core primer pairs with highpolymorphism were selected from the 1 05 published pairs.The genetic similarity coefficient of the 1 5 tested cultivarsvaried greatly,ranging from 0.3 5 to 0.9 1. It generally reached above average (≥0.6 5)with high at 0.80-0.9 1 forthe 8 tea cultivars and 4 control cultivars from South and North Fuj ian among the tested varieties.Consequently,there was little or no genetic differences among the cultivars.Applying the cluster analysis,all tested materialscould be divided into 8 groups at the similarity coefficient of 0.7 7 ,and 6 groups in the similarity coefficient of 0.6 6.The molecular fingerprints of the tested cultivars were established using the primer pairs combination of W08,D07and L1 1. The characteristic stripes obtained were between 2 1 0-6 30 bp,which could conceivably suffice successfulidentifications of individual cultivars.关键词
