| 摘 要： | 对24个大丽花品种的12个数量性状进行变异幅度、重复力及遗传相关性分析。结果表明:各性状品种内除花期受环境影响变异幅度较大外均表现稳定,品种间变异幅度较大,群体遗传多样性丰富;花径重复力较大,主要受遗传因素影响,其它性状不同程度受到环境影响,单朵初花期、单朵盛花期和整株花期受环境影响最大,但无性系内遗传稳定;花期间相关性较高,同时花期与花瓣数、花瓣长宽比均相关,而与花型和瓣型相关性较低,花径则基本是独立遗传。

| Abstract: | The 12 quantitative traits of 24 cultivars of Dahlia were investigated,the variation range,repeatability and genetic were correlation analyzed.The results showed that the characters of intraspecific were stable,in addition to outside florescence was significantly impacted by environment,but there was a significant variation in interspecific,rich in genetic diversity of population.Flower diameter repeatability was larger,other traits were impacted by environment in different degrees,single early flowering st... |
