摘　　要：【目的】综合评估黄秋葵品种的主要农艺性状,筛选出适合三亚地区种植的黄秋葵品种。【方法】在三亚地区进行黄秋葵品种田间比较试验,采用灰色关联分析法对供试8个黄秋葵品种的产量、果重、果长、果宽、单株结果数、株幅、节间长、始花期、果实蓟马危害指数及始花节位等10个主要农艺性状进行综合评价。【结果】各供试品种综合性状的等权关联度排序为幸福2号>幸福3号>五福>绿秋葵>幸福1号>9号>红秋葵>泰国Okra,综合性状的加权关联度排序为幸福2号>幸福3号>9号>五福>幸福1号>绿秋葵>泰国Okra>红秋葵。其中幸福2号和幸福3号综合性状表现优良,排序靠前,泰国Okra和红秋葵综合性状表现不理想,排序靠后。综合性状的加权关联度排序更符合田间观测结果。【结论】以灰色关联分析法评估选出的幸福2号和幸福3号黄秋葵品种综合性状表现优,适合在三亚地区推广种植。【Objective】The agronomic characters of okra（Abelmoschus esculentus L.） cultivars were assessed comprehensively, in order to screen okra cultivars suitable for planting in Sanya region. 【Method】The field experiment was conducted to compare agronomic characters of 8 okra cultivars in Sanya, Hainan. The main agronomic traits, including yield,fruit weight, fruit length, fruit width, fruit number per plant, plant width, internode length, first-flowering date, thrips hazard index and node of the first flower, were assessed comprehensively based on grey correlation analysis. 【Result】All tested okra cultivars were ranked according to equal-weighted correlation degree between comprehensive characters, as follows： Xingfu 2Xingfu 3WufuGreen okraXingfu 1No.9Red okraThailand okra, and all tested okra cultivars were ranked according to weighted correlation degree between comprehensive characters, as follows： Xingfu 2Xingfu 3No.9Wufu Xingfu 1 Green okra Thailand okra Red okra. Furthermore, Xingfu 2 and Xingfu 3 ranked in the top 2 of all cultivars, with good comprehensive characters, while Thailand okra and Red okra ranked in last 2 of all cultivars,with poor comprehensive characters. The order of weighted correlation degree more accorded with field observation results.【Conclusion 】Xingfu 2 and Xingfu 3 are screened out based on grey correlation analysis, which have excellent comprehensive characters, and are suitable for planting in Sanya region.
