Abstract:

Genetic variation and differentiation in cloned, seed produced, and wild tea plants of Camellia sinensis var. Assamica were analyzed by amplified fragment length polymorphism (AFLP) markers. Population diversity was highest in the wild and lowest in the cloned tea plants. Analysis of molecular variance revealed great variation among the groups (31.40%). Furthermore, a dendrogram constructed based on Nei’s genetic distance and principal component analysis clustered the tea population into three groups. Taken together, our study demonstrated that there is wide genetic variation among cloned, seed produced and wild tea plants of var. Assamica in Yunnan.
