| 摘 要： | 本试验对5年生东北铁线莲栽培群体主要数量性状的遗传参数及性状间的相关关系进行了研究。结果表明,群体内根重变异幅度最大,可以通过根重直接进行以高产为目标的选择育种;根重与须根数呈极显著正相关,且须根数在群体中的变异幅度较大。因此,须根数可以作为相关性状进行以高产为目标的选择育种。

| Abstract: | The article reported the study on genetic parameters of main quantitative characters and correlation among traits of Clematis manshurica Rupr that was five years old cultured group.The results indicated that variation extent of root weight was maximal,and root weight was the index that could be used as selective breeding of high yield.The root weight and quantities of fibril had significantly positive correlation,and the variation extent of quantities of fibril was larger.Consequently,the quantity of fibril... |
