茶树无性系品种茶树无性系品种clonal variety of tea plant 茶树无性系品种(elonal variety of teaplant)采用无性繁殖方法育成的茶树品种，称为茶树无沮三系品种或无性繁殖系品种。这种茶树选种方法在中国约于17一18世纪就已开始应用。无性系品种是从同一个茶树母体中取其一部分营养体(茎、叶、根等)进行扦插、压条繁殖新个体，不通过两性细胞结合后染色体的重新组合过程，故能保持繁殖个体的性状特性相对一致性和稳定性。通常无性系品种茶树的生长整齐，发芽一致，采茶省工，也可提高茶叶品质。其缺点是存在遗传基因的狭窄性.必须多品种搭配种植或以种子繁殖的方式加以克服。 茶树无性系品种按照使用的性质又分为单无性系、双无性系和多元无性系。单无性系是以一个独立的无性系为单位，进行无性繁殖方式繁殖茶苗在生产上应用，但有个别单无性系也可用产生的种子供生产上应用。若以两个不同特点的无性系，按照一定比例同时种植在一个茶园中产生的杂交种子叫做双无性系。多元无性系是指三个或三个以上不同特点的茶树无性系种植在同一采种园中产生的杂交种子。无性系的种子繁殖后代，品种纯度有所降低，故在生产中应对苗木择优使用。(陈炳环)
