摘　　要：【目的】在甘肃省河西地区建立科学合理的文冠果种质资源评价体系、综合评价和筛选适合在当地推广应用的文冠果优良品种,为河西走廊干旱半干旱区特色文冠果生态产业发展提供理论依据。【方法】运用层次分析法(AHP)构建分析模型计算指标权重,运用灰色关联度分析法(GRA)构建“理想品种”和参考数列,计算加权灰色关联度,对17个引进新种质从适应性、观赏性、丰产性对其进行评价与排序,最终完成综合评价与筛选。【结果】在验证层次分析模型合理的基础上,利用得出的权重值计算各参试种质评价指标加权关联度,结果表明:SW-2、SH-2、NSJH、NSZH、LD加权关联度在0.8(含0.8)以上,划分为Ⅰ级种质;NSF、LX、ZS-7、ZS-9、SW-1、SH-5、SH-5加权灰色关联度在0.7~0.8(含0.7)之间,划分为Ⅱ级种质;SKX、NH-1、ZS-4、LG-4、LG-8、ZS-1加权灰色关联度在0.7以下,划分为Ⅲ级种质。【结论】Ⅰ级种质观赏价值高、种子产量高、种仁出油率高、适应性强,各指标综合得分均接近“理想品种”,综合性状优良,适合在当地广泛推广;Ⅱ级种质植株要么观赏价值较高、油用潜力一般、产量低,要么产量高、出油率好,但观赏价值一般,总之综合性状较Ⅰ级种质植株稍差,这些种质应该根据栽培目的区别应用,观赏价值高的宜应用于城市园林绿化,而产量和种仁产油率高的种质应该推广在文冠果产业化发展基地广泛栽植,适宜运用在丰产园;Ⅲ级种质综合性状较差,无论观赏价值,还是产量和种仁出油率都一般,这类种植则不适宜在当地栽植,或者有待进一步做引种驯化和筛选工作。【Objective】To establish a scientific and reasonable evaluation system of Xanthoceras sorbifolia resources in Hexi,Gansu Province,and to make comprehensive evaluation and screening of excellent varieties of Xanthoceras sorbifolia suitable for local application,to provide a theoretical basis for the development of Xanthoceras sorbifolia ecological industry in arid and semi-arid regions of Hexi Corridor.【Method】Using the analytic hierarchy process (AHP) to build an analytical model to calculate the index weight,using the principle of grey relational grade analysis (GRA) to build “Ideal varieties” and reference series,and calculating the weighted grey relational grade,the 17 introduced new germplasm were evaluated and sorted from adaptability,ornamental and high yield,and finally completed comprehensive evaluation and screening.【Result】On the basis of verifying the rationality of the analytic hierarchy process AHP-RRB-model,the weight values obtained were used to calculate the weighted correlation degree of each germplasm evaluation index,the results showed that the weighted correlation degree of SW-2,SH-2,NSJH,NSZH,LD was above 0.8(including 0.8) and classified as Grade I germplasm NSF,LX,ZS-7,ZS-9,SW-1,SH-5,SH-5 were classified as Grade II germplasm according to the weighted grey correlation between 0.7 and 0.8(including 0.7).The weighted grey correlation degree of SKX,NH-1,ZS-4,LG-4,LG-8,ZS-1 was less than 0.7 and classified as Grade III germplasm.【Conclusion】The grade I germplasm has high ornamental value,high seed yield,large oil yield and strong adaptability,and its comprehensive scores are close to “Ideal variety” grade II plants have either high ornamental value,general oil potential and low yield,or high yield and good oil yield,but general ornamental value.In a word,their comprehensive characters are slightly worse than those of grade I plants,the germplasm with high ornamental value should be applied in urban landscaping,and the germplasm with high yield and oil yield should be wide
