摘要: 【目的】建立盆栽多头小菊株选的综合评价体系,为快速选育新品种提供依据。【方法】以盆栽多头小菊430个株系为试验材料,选取15个性状作为评价因子,采用灰色关联法和层次分析法相结合的方法建立评价系统。【结果】应用层次分析法分析各评价因子的权重值发现,决定盆栽多头菊小菊品质的性状主要为株型、花朵繁密度、株高和花色,所占比重分别为0.2016、0.1560、0.1190、0.0944。在此基础上,依据430个株系的灰色关联度值,将其分为3个等级,优选出43个株型丰满紧凑、花色鲜艳纯正、花朵繁密、综合性状优良的株系。【结论】应用灰色关联法和层次分析法相结合的方法,可以有效地对盆栽多头小菊各株系进行综合评价,并快速优选出符合育种目标的株系,为选择育种提供了一种相对科学严谨的方法。

Abstract: 【Objective】The present study was to establish a synthetic system for assessing the quality of potted chrysanthemum, and to offer a theoretical support for selecting and breeding of spray potted chrysanthemum. 【Method】A total of 430 potted chrysanthemum plants were used as materials and 15 characters were chosen as evaluation factors. The synthetic evaluation system was established by combining the grey correlation analysis and AHP method together. 【Result】AHP method was used to determine the weight value of various characters. The results showed that plant shape, flower dense, plant height and flower color represent a significant share. The weight of each affecting factor was 0.2016, 0.1560, 0.1190 and 0.0944. According to the grey correlation degree of 430 strains, they were divided into 3 grades. And eventually 43 strains with the good comprehensive characters (the good shape, bright and pure color, dense flowers, etc.) were picked out. 【Conclusion】The results show that the combination of the grey correlation analysis and AHP method can be used to evaluate the potted chrysanthemum strains effectively and select the objective ones quickly, it provides a scientific and precise method for selection breeding.
