A hybrid breeding method of a new primrose variety `Qunshiaochun'was provided. Including: interspecific hybridization and single plant selection. Interspecific hybridization is based on primuladen ticulate ssp. sinodenticulata Bal F. F. et Forr. W. W. Smi th as female parent and Primula pseudodenticulata Pax as male parent. The fruits of the hybrid are harvested for seed sowing and seedling transplanting. Six to fifteen leaves are selected from F1 generation with strong growth, light purple-red flowers and inflorescences. The height of flower bud is 4 42cm, and the flowering period is from December to February of the next year. When flowering, the individual plants are pollinated, picked and sown again. The selection criteria are the same as F1, and the pollination between plants is also carried out. After the F3 generation is formed by seed collection and sowing, 6 15 flowers with brilliant colors and 6 15 inflorescences are selected, and the fragrant individuals are primrose `Lion-making Spring'. The new cultivars selected by this method have high ornamental value, from one inflorescence of the original species to 6 15 inflorescence, with significant difference, high consistency and stability.
【技术实现步骤摘要】
一种报春花的培育方法
本专利技术属于花卉新品种的培育方法,具体地,涉及报春花新品种‘群狮闹春’的杂交育种培育方法。
技术介绍
报春花属植物全球约有500种,主要分布于北半球温带和高山地区,仅有少数种类分布于南半球,沿喜马拉雅山两侧至云南、四川西部是该属的现代分布中心。中国是报春花属植物自然分布较为丰富的国家之一,现已知并发表的种类有293种21亚种和20变种。云南地处中国的西南边陲,植物种类极为丰富,报春花属植物尤其突出,我国已知种类的绝大部分(约159)均分布于云南。报春花属植物花多艳丽,是美丽的观赏植物之一。英、美等国曾多次派人来我国采集标本,将种苗运回欧美栽培,成为植物分类学界和花卉园艺学界的一时之热潮。具不完全统计,英国由我国引入栽培的报春花种类多大110余种,并培育了许多美丽的园艺品种。许多品种已经商业化生产,并获得了很高的经济效益。中国的野生报春花资源虽然比较丰富,但国内未见有报春花新品种培育的报道。有报道称报春花种间杂交不育,因此,有必要进行报春花的新品种选育方法的研制。目前,现有技术未见报春花种间杂交育种方法以及以该方法获得的新品种的报道。专利技术 ...
