【摘要】 以沈阳农业大学自主选育的39个地被菊品种为试材,选取包括植株、花部及抗性等3个层面的31个性状作为评价因子,通过层次分析法构造两两比较的判断矩阵,确定指标层对目标层的权重值,利用灰色关联分析法确立"理想品种",结合层次分析法得出的权重值,计算各品种的加权关联值,进行等级评价。结果表明:该研究构建了综合评价体系,并对参试的39个地被菊品种进行了综合评价和等级划分,共划分为5个等级。Ⅰ级共11个品种,该级品种抗性强、观赏效果佳,可在我国北方园林绿地直接推广使用。Ⅱ级的10个品种优点较突出,但观赏性与抗逆性未能兼备。Ⅲ级9个品种的观赏性与抗逆性均需要改良。Ⅳ级与Ⅴ级品种的综合评价分别为较差及差,不建议推广使用。更多还原

【Abstract】 Thirty-nine ground-cover chrysanthemum cultivars,which bred by Shenyang Agricultural University,were selected as materials.31 traits were selected as evaluation factors,including plant,flower,and resistance.The grey correlation analysis method was used to establish the ideal cultivar,and the correlation value of each cultivar,which was calculated by the method of analytic hierarchy process.A scientific comprehensive evaluation system was constructed.Using this system,the testing 39 cultivars were classified into five grades.There were 11 cultivars in Grade I.These cultivars showed excellent ornamental and resistant characters.These cultivars should be used extensively in north area of China.Grade II 10 cultivars advantage prominent,but the ornamental and resistance failed to have both.Grade III 9 cultivars of ornamental and resistance are improved.Grade IV and grade V cultivars of comprehensive evaluation for the poor and poor respectively,was not recommended to use.更多还原
