摘要
为了探索食用型甘薯品种的科学评价方法,采用灰色系统理论中的品种灰色关联度多维综合评估分析法对12个试验品种的11个主要性状指标进行综合分析和评价。结果表明:各试验品种的优劣顺序依次为烟薯25、泰中6号、济薯04150、秦薯7号、阜薯062-20、济农83、商薯079-1、徐薯22(CK)、廊薯7-12、漯薯7号、冀薯65、皖苏178,其中烟薯25产量和综合评估均排在第1位,其综合评估关联度为0.8621,比对照高20.22%。说明该品种解决了高产与优质的矛盾,是一个较为理想的食用型甘薯品种,这与其生产上的表现一致。同时表明该方法能够较为科学地鉴定和评价食用型甘薯品种。
In order to explore a scientific evaluation method for edible sweet potato varieties,11 major agronomic characters of 12 varieties were analyzed by grey correlative degree multiple target comprehensive evaluation method. The results showed that the order of sweet potato varieties from good to bad was Yanshu 25,Taizhong 6,Jishu 04150,Qinshu 7,Fushu 062-20,Jinong 83,Shangshu 079-1,Xushu 22（ CK）,Langshu 7-12,Luoshu 7,Jishu 65 and Wansu 178. The yield and comprehensive evaluation of Yanshu 25 were both the first with the correlation degree of 0. 8621,which was 20. 22% higher than that of control. It indicated that Yanshu 25 solved the contradiction between high yield and high quality and was an ideal edible sweet potato variety,which was consistent with the performance in production. It also showed that this method could scientifically identify and evaluate edible sweet potato varieties.
