花生品种丰产性和稳产性非参数分析

摘要

Using the method of nonparametric statistics,the productivity and the stability of 9 peanut cultivars are studied . The results show that Zheng 86036-26-1 is the cultivar with good productivity and good stability,Pi and P′i in the method are good productivity indexes and Si is a good stability index. The method is simple,direct and practical and is fitted to evaluate new cultivars in regional experiments.%采用非参数统计方法,对9个花生品种的丰产性和稳产性进行了分析.结果表明,参试品种中只有郑86036-26-1是丰产性和稳产性均好的品种.该方法中提出的Pi和 Pi′是较好的丰产性指数,Si是较好的稳产性指数.该法具有分析简单、直观、实用的特点,适合于评价区域试验中的品种表现.
