摘要
以参加湖南省低镉水稻品种筛选试验的31个早稻品种为材料,将这些品种种在15个盆栽试验环境点,获得稻米镉含量数据,使用非参数统计方法-秩次分析法,对参试品种的稻米镉含量及其稳定性进行综合分析与评价,以筛选具有稳定低镉性状的早稻品种。结果表明,品种v20(两优早17)和v23(株两优706)属于稻米低镉性能和镉含量稳定性均较好的品种,适合一般污染区大面积种植;秩次分析法适用于低镉水稻筛选试验中品种低镉性能和镉含量稳定性评价,是一种实用、可行的数据处理方法。
In this research, the data of 31 early rice varieties which participated in low cadmium rice varieties screening trials in the15 selected test environments in Hunan, using non-parametric statistical methods-rank analysis to analyze and evaluate the Cd con-tent and stability of the tested varieties comprehensively. The results showed that Liangyouzao 17 and Zhuliangyou 706, which belong to low and stable Cd content rice varieties, could be widely planted in slight pollution soil. In screening low cadmium rice varieties test, the rank analysis method is a practical and forthright analysis method evaluating the Cd content and stability of the varieties.
