用于万寿菊DUS测试指南的标准品种的筛选(英文)

Selection of Example Varieties Used in the DUS Test Guideline of Tagetes L.

[目的]本研究以万寿菊花直径性状为例以期筛选出用于万寿菊DUS测试指南的标准品种。[方法]每个品种花直径两年的测试数据经采集后利用箱线图分析每个品种花直径的一致性和稳定性。[结果]根据箱线图所反映的各品种直径的变异性、测量值分布的对称性以及异常值情况,品种16、2、4被分别确定为花直径表达状态3.0-4.4,6.0-7.4和9.0-10.4cm的标准品种。[结论]箱线图是一种对品种进行总体分析的有效方法,它能够提供包括每个品种花的直径的实际和可能的表达范围,测量中间值和异常值在内的信息。该方法也为筛选其他数量性状的标准品种以及评价品种质量提供了参考。

[Objective] Taking the characteristic of flower diameter of Tagetes L.as an example,this study aimed to select example varieties used in the DUS Test Guideline of Tagetes L.[Method] Two continuous years of measurements of flower diameter of 25 varieties were collected and then analyzed by using the box plot to illustrate the uniformity and stability of flower diameter of each variety.[Result] According to the information of variability,distribution symmetry of measurements and outliers of flower diameter of varieties provided by box plots,variety 16,2 and 4 were selected as the example varieties for the three expression states with respective flower diameter of 3.0-4.4,6.0-7.4 and 9.0-10.4 cm.[Conclusion] The box plot is an efficient method for the general analysis of varieties,which provides information covering the actual and possible expression range,median and outliers of measurements of flower diameter of each variety.It also provides references for selecting example varieties for other quantitative characteristics and evaluating the quality of varieties.
