摘要
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。
The convertional cross breeding method was used to breed new varieties by using Nymphaea lotus var.pubescens as female parent and Nymphaea lotus as male parent in 1999.Two parental species are both night blooming tropical waterlilies.821 bybrid seeds were obtained.408 hybrid F1 seedlings were cultivated successfully.The main characters of the hybrid F1 seedlings were compared with their parents,and 4 hybrid seedlings with excellent characteristics were picked out.4 clones were obtained by asexual reproducti...
