摘要
1995-2000年通过引种利用杂种优势选育籽莲新品种,筛选培育出杂交籽莲新品系建选17号(太空莲2号营×(寸三莲65×红花建莲)),其杂种优势明显而稳定,经三年种植表明其产量比本地品种红花建莲增加40%以上。选育的另三个品系可望作为搭配品种加以利用。在推广应用杂交籽莲过程中,要防止混杂衰退。
The new line was selected by multiple cross-breeding the introduced cultivars of seed lotus during 1995-2000. It is Jianxuan 17(Taikonglian 2x(Cunsanlian 65xHonghua Jianlian)). The new line shows apparent and stable heterosis, with yield 40% higher than that of the local control cultivar for three years. The other new lines of seed lotus by cross-breeding may be useful as auxiliary cultivars. Procedures must be done for prevention of degeneration of these new lines by cross-treeding.
