本文用 Eberhart and Russell(1966)的模式和 G·C·C Tai(1975)的模式分析了黄淮冬麦区1985—1986年区域试验中11个小麦品种的基因型 x 环境互作。4次重复的随机区组设计的试验在7个地点进行。结果表明 Eberhart and Russell 的bi 对品种稳定性评价较为笼统。而 Tai(1975)的基因型 x 环境互作效应的分解,对新品种的推广和利用提供了较多的更为精确的重要信息。利用区域试验的数据进行这样分析的结果会有助于参试品种合理的推广和利用。
In this paper, the genotype x environment interactions of 11 wheat cultivars in the Huanghuai winter wheat region from 1985 to 1986 were analyzed using the model of Eberhart and Russell (1966) and the model of GC C Tai (1975). Four replicate randomized block design trials were conducted in seven locations. The results show that Eberhart and Russell’s bi evaluation of the stability of varieties is more general. The decomposition of Tai (1975) genotype x environment interaction provides more accurate and important information on the promotion and utilization of new varieties. The results of such analysis using the data from the regional trials will be helpful for the rational popularization and utilization of the tested varieties.
