Abstract： 'Zhenong 902' is a new tea cultivar suitable for processing green tea， which is selected from 'Jiuke-

ngzhong'  natural hybrid offspring and bred by systematic selection including the processes of single plant selection，

cutting propagation， strain comparison， and regional adaptation experiment. The results show that 'Zhenong 902' is

an early-sprouting cultivar with high quality. The baked green tea had wiry， curly and tippy， jade green appearance，

tender yellow and bright liquor color， clean and high aroma， heavy and mellow with sweet taste， fine and tender brewed

leaves with bright green color. Based on the first round picking in spring， the average content  of tea polyphenols，

amino acids， caffeine， catechins and water extracts in shoots with one bud and two leaves were 15.4%， 8.0%， 3.5%，

10.35% and 44.9%， respectively. It has high tolerance to cold， drought and anthracnose （HR）， but is sensitive to tea green

leafhopper（S）， It suitable for planting in Chongqing， Guizhou， Sichuang， Hu'nan and other areas with similar

climate condition. It showed a high percent of intact bud， one bud and two leaves by machine-plucking. It was

registeredregistered by Ministry of Agriculture and Rural Affairs in 2020 with the registration No. GPD  tea plant

（2020）330039.

不斷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。劳动力成本上升，优质、高产、早生、适宜机采品种的选育和推广成为茶叶稳定持续发展的必然趋势。浙农902是从鸠坑种种子后代中经单株选拔—扦插扩繁—品比试验—区域试验系统选育而成的适制绿茶新品种，机采芽叶完整度高，目标芽叶占比高，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）330039。

一、选育方法与过程

2000年从鸠坑种茶树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、发酵性能、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。……
