本文采用灰色系统理论中的关联度分析法,对水稻区域试验中的各参试品种进行了多性状的综合评判。分析结果表明;在注重产量、米质性状,兼顾其它性状的权重比例下,所进行的综合评判结果与大面积生产上品种的种植情况是一致的。初步认为本法同样适用于不同地区对最佳种植品种选择的分析。
In this paper, the gray relational analysis method in the theory of the system, the rice regional trials of the tested varieties of a comprehensive evaluation of multi-traits. The result of the analysis shows that under the weight proportion of yield, grain quality and balance of other traits, the result of comprehensive evaluation is consistent with that of large-scale production. It is initially believed that this Law is equally applicable to the analysis of the best choice of cultivars in different regions.
