摘要:通过对中茶111等10个无性系绿茶品种的茶苗成活率、茶树高树幅、新梢物侯期、发芽密度、鲜叶产量、制茶品质、耐寒性等性状进行分析,为良种鉴定评价提供科学依据。结果表明,中茶111、鄂茶8号、安庆8902、花秋1号4个参试绿茶品种适宜湖北及相似茶区发展种植。其中,中茶111为早生、高产、优质、耐寒性强的品种,鄂茶8号为早生、高产、优质、耐寒性较强的品种,安庆8902和花秋1号为中生、高产、优质、耐寒性强的品种。五峰602、栗早香2个参试绿茶品种不适宜湖北及相似茶区发展种植。

Abstract:The analysis on seedling survival rate, height, width, phenological phase, bud quantity, fresh yield, quality and cold resistance of ten clonal green tea cultivars provided scientific basis for the identification of improved varieties. The results showed that Zhongcha 111, Echa NO.8, Anqing 8902, and Huaqiu NO.1 are suitable to be cultivated in Hubei province and the area with climate similar. Zhongcha 111 is a early sprouting, high yield, fine quality and strong cold resistance green tea cultivar; Echa NO.8 is a early sprouting, high yield, and fine quality green tea cultivar; Anqing 8902 and Huaqiu NO.1 are medium sprouting, high yield, fine quality and strong cold resistance green tea cultivars. Wufeng 602 and Lizaoxiang arent suitable to be cultivated in Hubei province and the area with similar climate.

湖北省是中国的茶叶大省,近年来茶产业得到了快速发展,呈现出良好的发展态势和前景。湖北省现有茶园面积31万hm2左右,位居全国第三,但无性系茶树良种普及率较低,仅为29%,远低于全国无性系茶树良种普及率平均水平。而茶树品种是茶叶生产中最基础、最重要的生产资料,也是茶业可持续发展的物质基础,在茶产业发展过程中发挥了关键作用。因此,筛选出适宜湖北茶区发展种植的高产、优质、高抗型茶树(新)品种,可调整茶园品种结构,提高湖北省无性系茶树良种普及率,这对于实现湖北省茶产业安全、优质、高效生产和产业提档升级具有重要意义。为此,以中茶111、黔茶8号、花秋1号等10个无性系绿茶品种为参试品种,对其茶苗成活率、新梢物候期、鲜叶产量、制茶品质、抗逆性等指标进行综合性鉴定评价,以期为筛选出适宜湖北茶区发展种植的无性系优良品种提供科学依据。……
