摘要
[目的]以洞庭碧螺春专用茶树品种选育为目标,开展碧螺春优质茶树[Camellia sinensis(L.)O.Ktze.]单株选择研究。[方法]根据茶叶品质、产量、芽叶发育期、抗性等性状指标,筛选洞庭群体种优良单株。[结果]d-x-1、d-x-8、d-x-24单株的感官审评总得分和单个香气得分均较对照和其他株系高,春茶开采期比其他株系稍早(d-x-24稍晚2 d),春茶发芽密度高于对照和其他株系,鲜叶产量、百芽重、抗逆性等与对照和其他株系相差不多。总体上,这3个株系综合性状比对照和其他株系优异。[结论]筛选出d-x-1、d-x-8和d-x-24共3个优质碧螺春茶树新株系,为碧螺春品种选育奠定了基础。
[ Objective ] Aiming at breeding special tea tree variety to produce Dongting Biluochun tea, the study of good quality individual se- lection of Biluochun tea was carried out. [ Method] According to quality, yield, development period of bud and leaf, resistance and the other traits indices, its good individuals were selected. [ Result] d-x-I, d-x-8 and d-x-24 individual~ total scores of sensory evaluation and single a- roma score were higher than those of control and the other lines, their harvest period for spring tea were a little earlier than that of the other lines (except d-x-24 slightly late 2 days), their bud density for spring tea were higher than that of control and the other lines, while their fresh leaves yield, 100-bud weight, and resistance were similar to those of control and the other lines. In general, the comprehensive traits of these 3 lines, d-x-1, d-x-8 and d-x-24, were better than that of control and the other lines. [ Conclusion] The study selects 3 new good lines of Bilu- oehun tea, d-x-1, d-x-8 and d-x-24, and provides a foundation for breeding of Biluoehun tea varieties.
