| 摘 要： | 以草原3号杂花苜蓿通过茎段扦插建立的6个无性系群体为材料,比较了这些无性系在株高、再生速度及变异系数上的差异,分析了单株产量及相关农艺性状的变异性、相关性及多元线性回归关系,结果表明,综合性状以黑紫色、黄绿色和白黄色3个无性系较优;较多的分枝、较小的叶型、绝对高度大且茎叶比也较大的植株,预示有较高的头茬草产量。

| Abstract: | Six clones from Medicago varia cv.Caoyuan No.3 were established by cuttage.These clones was used to compared the height,growth speed and total coefficient of variation.The variation analysis,correlation analysis and REG analysis between yield and characters were conducted.Result indicate that the dark-purple clone,yellow-green clone and light-yellow clone were good in synthetical characters. |
