摘要:通過對中茶111等10個無性系綠茶品種的茶苗成活率、茶樹高樹幅、新梢物侯期、發芽密度、鮮葉產量、制茶品質、耐寒性等性狀進行分析,為良種鑒定評價提供科學依據。結果表明,中茶111、鄂茶8號、安慶8902、花秋1號4個參試綠茶品種適宜湖北及相似茶區發展種植。其中,中茶111為早生、高產、優質、耐寒性強的品種,鄂茶8號為早生、高產、優質、耐寒性較強的品種,安慶8902和花秋1號為中生、高產、優質、耐寒性強的品種。五峰602、栗早香2個參試綠茶品種不適宜湖北及相似茶區發展種植。

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.

湖北省是中國的茶葉大省,近年來茶產業得到了快速發展,呈現出良好的發展態勢和前景。湖北省現有茶園面積31萬hm2左右,位居全國第三,但無性系茶樹良種普及率較低,僅為29%,遠低于全國無性系茶樹良種普及率平均水平。而茶樹品種是茶葉生產中最基礎、最重要的生產資料,也是茶業可持續發展的物質基礎,在茶產業發展過程中發揮了關鍵作用。因此,篩選出適宜湖北茶區發展種植的高產、優質、高抗型茶樹(新)品種,可調整茶園品種結構,提高湖北省無性系茶樹良種普及率,這對于實現湖北省茶產業安全、優質、高效生產和產業提檔升級具有重要意義。為此,以中茶111、黔茶8號、花秋1號等10個無性系綠茶品種為參試品種,對其茶苗成活率、新梢物候期、鮮葉產量、制茶品質、抗逆性等指標進行綜合性鑒定評價,以期為篩選出適宜湖北茶區發展種植的無性系優良品種提供科學依據?!?br>
