茶树新品系‘白云0492’区域试验报告

Regional Test Report on New Tea Variety, Baiyun 0492

摘要: 为明确茶树新品系‘白云0492’（又名白云特早）的区域适应性，以‘福鼎大白茶’为对照品种，在福建省福安市、武夷山市和尤溪县3个区试点连续6年（2012-2017年）对白云0492的种植成活率、生长势、新梢生育期、发芽密度、鲜叶产量、制茶品质、抗性等方面进行鉴定。结果表明：白云0492新品系种植成活率高，生长势好，芽期特早，产量高，适制白茶、绿茶和红茶，抗逆性强，综合经济性状明显优于对照品种，适宜在福建省及气候相似的地区种植。

Abstract: The adaptability of a new tea variety, Baiyun 0492 (Camellia sinensis), for regional cultivation was tested, along with C. sinensis Fuding Dabaicha (Camellia sinensis)as reference (CK), for 6 years in Fu’an, Wuyishan City and Youxi. The characteristics of the tea bushes including survival rate, growth potential, phenological phase, bud density, fresh leaf yield, finished tea quality, and environmental resistance were monitored. The results showed that the new cultivar grew well at the sites exhibiting a high survival rate, extra-early phonological phase, and strong stress resistance, as well as high-yield, high-quality white, green, and black teas made from the plucked leaves. It was considered suitable for large-scale cultivations in the region.
