Six genotypes of Tea Camellia sinensis L. i.e., Indonesian, Sri Lankan, Ruopi, Qi men, Chuye & Japanese were tested at NTRI during 2008, for 8 qualitative & 12 quantitative characters. Germplasm was classified into three clusters based on qualitative traits analysis using wards method.This indicates the trait homology between Indonesian & Qi Men for Leaf shape, leaf margin, leaf lower surface, leaf upper surface, shoot color,& posture of leaf base. The linkage distance of their homology is 1.4 LD. The highest value for Veins pairs per leaf showed by Indonesian (13.60), followed by Qi men...
