摘要
采用灰色系统理论中关联度分析结合稳定性分析的多目标决策分析方法，对１９８４～１９８６年在江苏淮南麦区７个有代表性试点鉴定的１０个小麦品种进行综合定量评估。结果表明，灰色关联度排序和综合决策值排序所获得的综合评估结果与各品种的实际表现基本一致。结合稳定性分析的多目标决策分析法综合评估了品种的产量潜力、稳定性及其适应种植的地区。扬麦５号在不同生态环境的试点上种植均表现为高产、稳产、适应性广。扬州试点的生态效应最适宜小麦综合性状的发育，是江苏淮南地区小麦产量育种的适宜场所。还讨论了关联度分析和多目标决策在遗传育种其它方面应用的可能性。
Mathematical methods of the relational grade analysis and multiple-aim decision combined with stability analysis in the grey system theory and their application in assessing new wheat varieties were described with a set of data from a regional test of 10 winter wheat varieties grown in the lower Yangtse valley during 1984～ 1986. The results of thisstudy showed that the two methods were effective. Multiple-aim decision combined with stability parameter(bi)led us to integrally evaluate yield potential,stability of wheat variety andits suitable cropping region. Yangmai No.5 is found to be the most high-yielding,stable andwidely adapted in the 10 wheat varieties tested. Yangzhou is a more suitable site for breedingwheat varieties with high-yielding and wide adaptability in the lower Yangtse valley becausethe ecological effect there has least fluctuation from year to year and is favourable for development of multiple traits in wheat variety.
