Relationship of Italian and Chinese Tea Germplasm (Camellia sinensis (L.) O.Kuntze), based on microsatellite analysis
The only tea cultivation in Italy is located in Lucca, a city and a province in Tuscany.The major part of the plants of this cultivation comes from the seeds of a common mother plant, still present at the Lucca Botanical Garden, of unknown origin.Another plant imported from Kyoto, Japan, has generated, through cuttings, many other plants that make up a separate plot.In this study, 66 tea cultivars belonging to the germplasm collection of the China National Germplasm Tea Repository (CNGTR) in the TRICAAS located at Hangzhou, Zhejiang, China, and 17 from the Italian cultivation were studied by means of SSR markers.The aim of the study was to determine the genetic relatedness between these two groups, in order to find the possible origin of the Italian tea.In total 84 genotypes were analysed using 63 SSRs of 15 different linkage groups.The results showed a close correlation between the sixteen samples derived from the plant present at the Lucca Botanical Garden and the Chinese tea cultivars.In particular, these samples appear to have a similar DNA to the cultivars of the Zhejiang provinces.The sample imported from Kyoto,on the other hand, probably belongs to the assamica variety.
