欧报春(Primula vulgaris)不同花色与色素关系及花色遗传初步分析

为了掌握欧报春各花色遗传规律服务于良种生产,通过对欧报春各色花进行色素吸收光谱和薄层层析分析,进行不同花色杂交研究,分析了欧报春各色花所含色素类型及各花色遗传规律。结果显示欧报春群体含多种花色素,单株也可含有多种花色素,形成多变的粉色、红色及蓝色花。黄色深浅主要由类胡萝卜素含量决定。白色对粉色及黄色为隐性遗传,黄色、粉色为显性遗传并有数量遗传特征,黄色与粉色独立遗传。蓝色为多基因控制的隐性遗传,并具有数量遗传特征。

Kinds of pigments in flowers and inheritance of flower color of Primula vulgaris were studied by analyzing absorption spectrum and thin-layer chromatography(TLC) of pigments and by crossing analysis of different flower colors in order to get hereditary rules for seed production.The results show that there could be kinds of anthocyanins in colony or single primrose that forms various red,pink and blue colors of flowers.Depth of yellow was mainly determined by content of carotinoid.The color of white is reces...
