摘　　要：应用模糊综合评价方法,对2003～2004年全国超甜玉米区试新组合的6个生产性能进行了定量化评价。结果表明:①用模糊数学综合评价能够将多种性状指标归纳为一个统一的量化综合评价指标(模糊综合指数,FCI),该指标能较好地反映各新组合的实际综合生长性能水平,所获得的最终评价值不仅能反映各评价单元之间的相对级别,而且能直接反映它们的绝对等级。②根据FCI划分为5个综合评价等级,绝大多数超甜玉米新组合(或品种)处于3～4级。我国超甜玉米新品种选育需要种质资源的创新和选育水平的提高。In this paper, new combinations in 2003 - 2004 national super-sweet corn regional test had been comprehensively and quantitatively evaluated using fuzzy comprehensive evaluation method, the results showed that： ①using fuzzy comprehensive evaluation method, the evaluated traits could be converted into one united, quantitative and comprehensive evaluation index（the fuzzy comprehensive evaluation index, FCI）. The FCI could reflect practical comprehensive production performance of all combinations,the final evaluation values could reflect both the relative grades between evaluation factor and the absolute grades directly. ②according to 5 grades of FCI from low to high, most of new combinations were in 3 - 4 grade in the stage, so new combinations had the need to innovate germplasm resource and raise the level of super-sweet corn-breeding.
