| 摘 要： | 通过对在新疆栽培的15个国内外红花品种的试验研究,利用12个农艺性状,根据遗传距离,用系统聚类方法,对品种材料进行分类。聚类开始,把遗传距离最近的两个品种聚为一组,随后不断将遗传距离最近的组和品种聚合,直至把所有品种都聚在一个组内。聚类结果,15个红花品种可分三个类群,为红花育种正确选配亲本提供理论依据。

| Abstract: | There were 15 cultivars of saffiower in this experiment and 12 agronomical Characters being chosen for cluster analysis. The cluster system used with genetics. Distance Coefficients. It started from the nearest. Distance coeffleient and ended to the lest the research showed that there were 3 groups of different genetic patterns which can provide information for saffiower breeding. |
