Abstract: Eight newly developed germplasms of Dangui（Camellia sinensis） were compared to Huangdan（Camellia sinensis）（CK）on their botanical characteristics, tea quality, photosynthetic properties and biochemical compositions. The results showed that the new varieties were semi-opened shrubs with elliptical or long elliptic leaves. All of the germplasms had middle- to small-size leaves, and few hairs on their olivine bud leaves. The fresh leaf yields of DG-1, DG-3, DG-5, DG-7 and DG-8 were higher than CK. The oolong tea made from the leaves of DG-1, DG-2, DG-5 and DG-8 were judged by the sensory panels to be superior to that from CK. The net photosynthesis rates of the teas were 11.22～14.22 μmol·m^-2·s^-1, with DG-6 being the highest and DG-2 the lowest among them. Their transpiration rates were 2.58-4.65 mol·m^-2·s^-1, with DG-1 being the highest and DG-4 the lowest among the cultivars. The contents of amino acids in the tea leaves were between 3.58% and 6.41%, as DG-1, DG-3 and DG-5 contained more than the others. Their EGCG contents were 87.5-113.4 mg g^-1, higher in DG-4 and DG-7. Whereas, the total catechins were 156.20～208.46 mg g^-1 for all, with DG-4, DG-6 and DG-8 higher than the others. The comprehensive quality of DG-1, DG-5 and DG-8 were higher than the others.
