甘蔗引进品种的模糊综合评判分析

采用模糊综合评判分析,对我所1993-96年从广东、广西、四川引入的28个品种进行综合分析。结果表明:桂糖84/332、粤糖85/2549、粤农81/762的评判值均大于对照种桂糖11(0.7524),综合性状突出,应给予加大繁殖,推广;粤农79/309、粤糖85/1589、桂糖86/267、粤农87/1257的评判值均大于0.5,远远高于对照种ROC10(0.2859),综合表现良好,可以进一步扩大试验;粤农88/488、粤农88/489、川糖88/598、川糖85/591的评判值低,综合表现差,但是其蔗糖分高,可考虑作为高糖亲本利用。

Analysis of the fuzzy comprehensive evaluation for introduced varieties of sugarcane

Analysis of the fuzzy comprehensive evaluation was carried out to evaluate 28 varieties of sugarcane, which had been introduced from Guangdong, Guangxi, Sichuan to Yunnan during 1993-1996. The results showed as follows. With the best comprehensive characters, some varieties such as Guitang 84/332, Yuetang 85/2549, Yuenong 81/762, whose evaluation values were higher than that of the Guitang11 (CK 2, 0.7524), suggested to be accelerated propagation and popularization. The comprehensive characters of Yuenong 79/309, Yuetang 85/1589, Guitang 86/267, Yuenong 87/1257, were much higher than that of ROC 10(CK 1, 0.2859). These varieties need to be experimented again. The comprehensive characters of Yuenong 88/488, Yuenong 88/489, chuantang 88/598, chuantang 85/591 were low. They can not be used directly, but can be used as crossing parents considering their high sucrose contents.
