Abstract: 'Zhenong 901' is a new tea cultivar suitable for processing green tea, which is selected from 'Jiukeng' naturalhybrid offspring and bred by systematic selection including the processes of single plant selection, cutting propagation,strain comparison, and regional adaptation experiment. The results showed that 'Zhenong 901' is an early-sproutingcultivar with high quality. The baked green tea has tight and curly sharp with tips, jade green appearance, tendergreen and bright liquor color, clean and high aroma, fresh and umami taste, and tender and even brewed leaves with bright green color. Based on the first round picking in spring, the average contents of tea polyphenols, amino acids, caffeine, catechins and water extracts in one bud and two leaves were 14.4%, 8.5%, 3.4%, 9.68% and 48.8%,respectively. 'Zhenong 901' also showed strong cold and drought tolerance, and is suitable for planting in Chongqing, Guizhou, Sichuang, Hu'nan and other areas with similar climate condition. It was registered by Ministry of Agriculture and Rural Affairs in 2020 with the registration No. GPD tea plant(2020)330038.

名優茶是我国主要的茶叶品类,生产效益好,对我国茶产业贡献巨大。优质、高产、早生绿茶品种的选育和推广是春季高档名优茶生产的重要保障[1]。不断选育符合生产需求的茶树新品种一直是茶学研究的重点之一。浙农901是浙江大学茶叶研究所从鸠坑种的自然杂交后代中采用单株选育法育成的早生、优质、适制名优绿茶的茶树新品种,于2020年12月通过农业农村部非主要农作物新品种登记,登记编号:GPD茶树(2020)330038。

一、选育方法与过程

2000年从鸠坑种上收集自然杂交种子,2001—2004年对种子苗进行单株鉴定,通过主要经济性状、生长量、产量等观测,选出优良单株,将此优良单株进行扦插扩繁后,于2006年3月在浙江杭州布置品系比较试验,以国家级早生绿茶品种福鼎大白茶为对照种,试验设3 次重复,随机区组排列,小区面积10.5 m2,种植规格为单行条栽,行距和丛距分别为150 cm×33 cm,每穴2 株。……
