摘要: 以蝴蝶兰Phalaenopsis黄花系品种P. Taipei Gold（2n ＝ 3x ＝ 57）作母本进行杂交育种有一个突出的问题是不育性障碍，为了克服这种障碍，多年来选择不同的父本进行杂交，终于发现采用 P. Sara Gold作父本进行杂交，收到蒴果1个，培育出杂交后代群体180株，其中有开花株99株。对杂交后代株高、冠幅、着花量、花径、花箭数、侧枝数及花色、唇瓣颜色和花瓣上的斑点进行观测记载。结果表明：杂交后代生长发育指标优于双亲的株数百分比：株高、冠幅、着花量、花径、侧枝数和花箭数分别占67.68%，86.87%，61.62%，24.24%，21.21%和26.26%；花瓣和唇瓣的颜色，基本遗传了双亲的特点，91%的后代花瓣颜色与双亲相似，74%的后代唇瓣颜色与双亲相似，90%的后代花瓣上出现了斑点。以P. Taipei Gold作为母本成功杂交在国内首次报道，为蝴蝶兰黄花系杂交育种提供了实践依据。图1表1参6Abstract: Since the cross of the female parent of Phalaenopsis Taipei Gold（2n = 3x = 57） always aborts，we tried to select different cultivars as the male to cross with P. Taipei Gold. P. Taipei Gold crossed with P. Sara Gold producing a capsule to breed 180 young plants of which 99 flowered. Offspring height；leaf length；flower diameter；the number of flowers，pedicels，and branches；flower and labellum color；and petal spots were compared. As a result，compared to the parents，offspring were taller （67.68%），had longer leaves （86.87%），had more flowers （61.62%），had larger flowers （24.24%），had more branches （21.21%），had more pedicels （26.26%），had petal color more like the female parent or male parent （91%），had labellum color more like the female parent or male parent （74%），and inherited their spot on the petals from P. Sara Gold（90%）. Thus，P. Taipei Gold as the female parent was first crossed successfully；this research showed that it was practical to cross Phalaenopsis with yellow flower. ［Ch，1 fig. 1 tab. 6 ref.］
