Abstract

The genetic diversity and differentiation of 91 individuals from five populations of Longjing tea landrace were characterized by 48 pairs of SSR markers. It was showed that the level of genetic diversity within Longjing tea population was high. The polymorphism information content (PIC) was ranging from 0.0567 to 0.7476 and the average PIC was 0.4382. Among 48 SSR sites in study, 16 was high polymorphism, 30 was medium polymorphism. Hardy-Weinberg equiliberum (HWE) test showed that 33.3% SSR sites were in accord with the HWE and 66.7% sites were not in HWE. AMOVA analysis showed that percentage variation among populations was 3.45% and percentage variation within individuals was 94.98%. The genetic differentiation was lower in Longjing tea population, the fixation indices within individuals and among populations was 0.0502 (FIT) and 0.0345 (FST) respectively.
