利用变异系数法和欧式距离值法分析四川省小麦区试试点分辨力

为了比较目前四川省小麦区试试点对参试品系的区辨力,本文利用2010～2011年四川小麦区试5个组共计60个参试品系的数据,采用变异系数法和欧式距离法对8个试点的区辨力进行比较分析。研究表明,变异系数法与欧式距离值法整体趋势一致,四川省小麦区试试点分辨力大小顺序是：绵阳〉射洪〉资中或内江〉乐山〉宜宾〉双流〉南充。笔者认为,欧式距离值侧重于基因型与环境互作效应,相对较为准确。...

In order to compare the discrimination of different sites in wheat regional trials of Sichuan province,the data of the wheat regional trials of Sichuan province from 2010 to 2011 were collected,and the site discriminations were analyzed with two different methods（Coefficient of variation and Euclidian distance）.The results showed that the conclusions of the two methods were almost the same in general.The sites discriminations was in order of Mianyang Shehong Zizhong or Neijiang Leshan Yibin Shuangliu Nanchong.It was concluded that Eucl
