【摘要】 [目的]为桂职1号的大面积推广应用提供理论和实践依据。[方法]以福鼎大白(华茶1号)为母本、上林安塘种为父本杂交后代(F1代)群体中选育所得的无性繁殖系,育成特早生、优质、高产茶树新品种桂职1号。2010~2013年采用随机排列对比法设计品比试验,对该品系的植株性状、成活率、发芽密度、春季芽萌发期、鲜叶产量、制茶品质、生化成分和抗性等进行鉴定比较。[结果]桂职1号春季萌发期比福鼎大白(CK)提早10 d以上,产量与品质都超过福鼎大白。春茶和秋茶占全年总产量近60%;制成绿茶外形紧结显翠,夏茶没有其他品种茶的苦涩味,非常适合制成绿茶;水浸出物、茶多酚和咖啡碱含量比福鼎大白低,氨基酸含量虽比福鼎大白低,但仍处于较高水平,香气和滋味比福鼎大白好;抗逆性、抗病虫害都强于福鼎大白。[结论]桂职1号在广西多点种植表现良好,值得大面积推广。更多还原

【Abstract】 [Objective] To provide theoretical and practical basis for the popularization of Guizhi 1. [Method]Clone was taken from the filial generation( F1generation) of Fuding Dabai( Huacha 1,female parent) and Shanglin Antang variety( male parent) to cultivate the new early and quality tea variety—Guizhi 1. Random arrangement and contrast method was adopted for the variety test from 2010 to 2013 to compare the plant characters,survival rate,germination density,germination period,yield of fresh leaves,tea quality,biochemical properties,and resistance of this strain. [Result]Guizhi 1 germinates 10 days earlier than Fuding Dabai( CK),but its yield and quality is higher. Spring tea and autumn tea account for nearly 60% of the year total; green tea has emerald green leaves and compact shapes,summer tea has no bitterness as other varieties,so it is suitable to make green tea. It has lower concentration of aqueous extract,tea polyphenols and theine than Fuding Dabai does,and also lower concentration of amino acid( but still high in absolute value),better flavor and taste,stronger resistance against stress,disease and pest. [Conclusion] Guizhi 1 performs well in multiple planting plots in Guangxi,so it is worth further promotion.更多还原
