Abstract

Abstract: The genetic diversity of four local tea plant [Camellia sinensis (L.) O. Kuntze] populations in Guizhou was analyzed using random amplified polymorphic DNA (RAPD) markers to breed characteristic excellent cultivars. The genetic distance of four populations including C. sinensis ‘Guiding-niaowangcha’ (G), C. sinensis ‘Duyun-maojiancha’ (D), C. sinensis ‘Meitan-taicha’ (M) ,and C. sinensis ‘Shiqian-taicha’ (S) was 0.1792-0.8328, 0.1745-0.8518, 0.1480-0.6507, and 0.1516-0.8691, respectively. In addition, based on Nei’s gene diversity index, Shannon’s index ,and RAPD bands polymorphism analysis, the genetic diversity among four populations was G>D>M>S. Our data showed that these populations had a rich genetic diversity. Their genetic variation was mainly distributed within populations.
