中国西北春谷区区试品种(系)的非参数统计分析与评价

The Analysis and Evaluation of Spring Millet Varieties in Northwest of China Regional Trial with Nonparametric Statistics

为了给品种鉴定、品种布局和推广应用提供一些科学依据,应用非参数统计法对2006年中国西北春谷区中晚熟组的区试资料进行了统计分析与客观评价,结果表明:(1)长农36号和长0301的丰产性较好,产量低于和显著低于它们的品种出现率Pi、P’i分别为71.4%、71.4%和70.1%、68.8%。(2)品种间的产量稳定性没有显著差异。(3)品种间差数显著的出现率Dj各试点均达到90%以上,部分试点Dj达到了100%,说明所有试点对品种差异具有较高的分辨力。

To provide scientific evidence for varietal verify, distribution and application, the data of 2006 spring miUet varieties in middle to late maturity group in northwest regional trial of china were studied by means of nonparametric statistics methods. The results indicated as the following： （1） Changnong 36 and Chang 0301 are two high-yield group, the frequency value of P i （%） and P＇i（%） of the varieties, which yields is lower and prominent lower than them, were 71.4, 71.4 and 70.1, 68.8 respectively.（2） The stabilization of yield hasn＇t prominent difference. （3） The prominent difference frequency Dj reach 90% in most regions, and some regions reach 100%. This result indicated that the distinguish of varieties difference in diverse regions is high.
