广东省超甜玉米新组合模糊综合评价

Fuzzy Comprehensive Evaluation on the New Cross Combinations of Super-sweet Corn in Guangdong Province

应用模糊综合评价方法,对广东省2000-2002年超甜玉米的一些新的杂交组合进行区域试验,在鲜穗产量、株型性状、生育期、抗逆性、品质等方面进行了定量化评价。结果表明:各组合的模糊综合指数(FCI值)可以反映综合评价水平的高低。同时,该方法在评价因子的定量化方面更加准确和可靠。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,而且也能直接反映它们的绝对等级。

New cross combinations were subjected to regional test during 2000-2002 in Guangdong Province by using fuzzy comprehensive evaluation method. The evaluation factors included fresh spike yield, plant type traits, growth duration, resistance and quality. The results showed that the fuzzy comprehensive indexes for the combinations could well reflect the practical quality levels of the corn varieties. This method is more accurate in quantifying the factors evaluated in comparison with the weighted aggregative index method. The evaluation values finally obtained could reflect both the relative grades between evaluation factors and the absolute grades directly.
