茶树实生苗数量性状相关关系研究

摘要

The garden identification and screening is one of the important procedures of tea seedling. The plant height, stem size, leaf number and branching number of 2398 one year old tea seedling of different cultivars were studied by Pearson's product-moment on relationship. Based on the result, the author of this article suggest to use plant height, stem size and branching number to select fine individuals.%实生苗苗圃鉴定与筛选是茶树育种程序中最早也是最关键的一个程序。本研究以不同品种资源2398株一年生实生茶苗为对象，采用皮氏积矩相关系数法对株高、茎粗、分枝数、叶片数4个数量性状进行相关性研究和分析。根据研究结果，笔者建议在实生苗苗圃鉴定与选择时用株高、茎粗、分枝数三个数量性状来选择优良单株。
