Abstract: Ruiming(Camellia sinensis) was newly bred from the natural hybrids of Ruixiang (Camellia sinensis) by the Tea Research Institute, Fujian Academy of Agricultural Sciences usingthe single plant breeding method. It was a strongly aromatic, high-quality oolongtea. In the 5^th round of the National Regional Trial for Tea Cultivarsfrom 2013 to 2018, it displayed, as compared with Huangdan (CK), a latephenological phase in 4 districts and a similar yield in Guilin but notstatistically significant 9.41%～24.86% higher yield inthe other 3 districts, but only the Pu'er district in Yunnan has a significant difference. Thequality of the tea processed from Ruiming leaves in Guilin was comparable tothat of CK, but superior to those in the other districts. The Ruiming cultivarwas strongly cold and drought resistant but sensitive to Jacobiascaformosana infestation as CK. Therefore, Ruiming was deemed to be ahigh-yield, high-quality, stress resistant, late-growing oolong tea cultivarsuitable for cultivation in areas such as Fu'an in Fujian, Pu'er in Yunnan,Guilin in Guangxi, and Yingde in Guangdong.
