柔毛齿叶睡莲×埃及白睡莲新品种选育

Breeding of New Varieties of Nymphaea lotus var.pubescens×Nymphaea lotus

采用常规人工杂交育种技术,以夜花型热带睡莲柔毛齿叶睡莲(Nymphaea lotus var.pu-bescens)为母本,埃及白睡莲(Nymphaea lotus)为父本,进行杂交。获得杂交种子821粒,育成F1植株408株,经过对其F1代的分离观察,从中筛选出4个性状优良的单株,并采用无性繁殖形成无性系。通过与父母本主要观赏性状的比较,这4个优良无性系在花色、花径、叶色等方面优于父母本或别具特色,具有较高的观赏性。品种性状特征描述按国际睡莲新品种登陆的标准进行,色彩描述采用国际花卉新品种登陆通用的英国皇家园艺学会色谱2003年版。
