| 摘 要： | 【目的】利用综合灰色关联度加权法对玉米品种的各主要性状进行综合评价分析,为农作物新品种评价提供科学参考。【方法】采用2008年广西玉米区域试验数据,利用决策分析中的多属性决策理论,运用综合灰色关联度的方法确定各性状的客观权重,然后对玉米品种进行评价。【结果】玉米品种HM-2的综合评价值最大,其次是哈宝7号,最小的是XQ-9;玉米品种HM-13产量最高,其次为联玉19,产量最低的是KY116。【结论】在实际生产中,不能只考虑产量这一单一性状来选育新品种,应尽量选择对产量和环境的互作有影响的几个重要性状进行综合评价。综合灰色关联度加权法可有效减少某些人为的设定因素,使新品种的选育、评价和鉴定更科学、客观、符合实际。在玉米的育种实践工作中,其可作为辅助工具,以选育出高产、稳产、低风险、综合性状优良的玉米新品种。

| Abstract: | [Objective]In the present study, various characteristics of ten corn varieties were comprehensively evaluated using grey correlation degree weighing method in order to provide references for evaluation of new crop varieties.[Method]Based on the multiple attribute decision making theory, the grey correlation degree was used to weigh different characteristics of ten corn varieties, viz., XQ-3, WD-6, Habao 7, HM-2, Lianyu 19, XQ-9, KY116, WD-37, HM-13 and Zhengda 619. The data was obtained from regional test t... |
