灰色多维综合隶属度评估方法在国家大豆区试品种评价中的应用

用灰色多维综合隶属度评估方法对参加2011年国家黄淮海夏大豆区域试验德州试验点l5个大豆新品种(系)的11个性状进行综合评价分析,结果表明:中黄46(品系)、中黄45(品系)、冀09B2(品系)为优良品系,晋遗55(品系)、冀09B5(品系)、冀豆12(CK)、鲁97013-1(品系)、中作06-875(品系)、中作J8023(品系)、中作05-6171(品系)为较好品系,晋豆40(品系)、K06-47(品系)、邯6192(品系)、中作07-22(品系)表现一般,晋大78(品系)表现较差。评价结果与品种实际性状表现吻合,说明采用此方法能比较客观、科学、合理地综合评价新品种(系)。

Application of Grey Multidimensional Comprehensive Membership Grade in Evaluating National Soybean Cultivar Trials

The study evaluated comprehensively 11 traits from 15 new soybean varieties (lines) in DeZhou location of National Huang-Huai-Hai soybean regional trials by using grey multidimensional comprehensive membership grade method. The result indicated that Zhonghuang46(line), Zhonghuang45(line) and Ji09B2 (line) were superior varieties, and Jinyi55(line), Ji09B5(line), Jidou12(CK), Lu97013-1(line), Zhongzuo 06-875(line), ZhongzuoJ8023(line) and Zhongzuo05-6171(line) were better varieties, while Jindou40(line), K06-47(line), Han6192(line) and Zhongzuo07-22(line) were ordinary varieties, and Jinda78(line) was poor variety. This was very consistent with practical experience and thus the method can be used to effectively evaluate soybean new variety (line).
