早生优质高产绿茶茶树新品种湘波绿2号选育研究

The Breeding of New Early-budding and High-yielding Green Tea Cultivar——Xiang Bo Lü 2

以优质绿茶适制品种福鼎大白茶的天然杂交后代为育种材料,经系统选种、无性繁殖,育成了早生优质高产绿茶茶树新品种"湘波绿2号"。经多年品种比较、多点试种和生产示范的结果表明:"湘波绿2号"为早芽种,春季萌发期与福鼎大白茶(对照)相当;产量高,经方差分析与对照差异达极显著水平;内含物丰富,氨基酸含量显著高于对照;适制绿茶,香气高长、滋味醇厚鲜爽;抗寒性、抗旱性较强,均超过对照。"湘波绿2号"于2011年通过湖南省农作物品种审定委员会品种登记。

New early-budding and high-yielding green Tea cuhivar--＂Xiang Bo Lu 2＂, suitable for processing green tea, has been selected by means of systematic selection and vegetative propagation from the progeny of natural hy- bridization of Fuding Dabai Cha and other cuhivars. After several years＇ variety comparison, several areas＇ plant ex- periments and production demonstration, the results indicated that ＂Xiang Bo Lu 2＂ was sprouted early in spring just like ＂Fuding Dabai Cha＂ which was the control; fresh leave yield was higher more than the control by variance analysis, and the difference reached extremely significant level; inclusion in leaf was rich, especially amino acid content ex- ceeded the control obviously; suitable for the manufacture of green tea, the taste and flavor of processed green tea were excellent; cold resistance and drought resistance were stronger than the control. In 2011, ＂Xiang Bo Lu 2＂ has the registration of new tea cuhivar by Hunan province Crop Variety Approval Committee.
