矮牵牛新品种“0210”的性状整齐度测验

Testing of Character Variability of New Variey "0120"

株高、冠幅、花径是矮牵牛的重要观赏性状。通过变异系数、新复极差测验等统计方法对矮牵牛新品种0210的株高、冠幅、花径等性状整齐度做了分析。结果表明,新品种"0210"这个品种冠幅的整齐度均比"梦幻"紫色、粉色、白色品种的冠幅整齐度高。株高的整齐度比"梦幻"紫色品种株高整齐度高,但是比"梦幻"粉色、白色品种株高整齐度差。新品种"0210"与"梦幻"系列不同颜色的矮牵牛品种之间的株高差异是极显著的,与"梦幻"紫色品种十分接近;"0210"的平均花径是8.22cm,比梦幻其他颜色的品种花径都大,但是花径这个性状的整齐度较其他品种差。"0210"的大花比率比"梦幻"玫红的大花比率高。

Height, breadth and diameter of corolla are the important ornamental characters of petunia. The uniformity of three characteristic of the new variety ＂0210＂are analysed by the ways of coefficient of variation and new multiple range test. The uniformity of three characteristic of the new variety ＂0210＂and the variety ＂Dream＂ which is the most popular variety of petunia in the world are compared. The result indicated that The variability of breadth of the new variety ＂0210＂ is less than the purple, pink, white of ＂Dream＂; The variability of height of the new variety ＂0210＂ is less than the purple of ＂Dream＂, but more than the pink, white of the ＂Dream＂. the difference of height is remarkable between the new variety ＂0210＂ and the pink and white of ＂Dream＂ ,the height of the new variety ＂0210＂is close to the purple ＂Dream＂; the diameter of corolla of new variety ＂0210＂ is 8.22cm, is more than the other variety ＂Dream＂. But The variability of diameter of corolla is more than the ＂Dream＂. Big flowers percentage of the ＂0210＂is higher than the rose of the ＂Dream＂.
