摘　　要：【目的】对云南湿润生态型的甘蔗细茎野生种F1代创新种质材料进行分类,为提高云南甘蔗细茎野生种F1代创新种质的利用效率提供科学依据。【方法】将集对分析理论与模糊聚类原理相结合,采用同一度分类分析方法对20个云南湿润生态型甘蔗细茎野生种血缘F1代的9个主要性状进行分类分析。【结果】20个云南湿润生态型甘蔗细茎野生种血缘F1代种质材料被分为8个类型:Ⅰ类包括1个材料,出苗中等,分蘖率低,有效茎少,细茎,低产,低锤度;Ⅱ类包括1个材料,出苗中等,分蘖率高,有效茎多,成茎率高,高产、高锤度;Ⅲ类包括8个材料,占参试材料总数的40%,出苗中等,有效茎数中等,中大茎,中等产量;Ⅳ类包括1个材料,出苗分蘖一般,大茎,高产,低锤度;Ⅴ类包括两个材料,出苗好,分蘖率中等,有效茎数多,中大茎,高产,锤度偏低;Ⅵ类包括5个材料,出苗分蘖好,有效茎数多,中小茎,高产,中等锤度;Ⅶ类包括1个材料,出苗分蘖差,有效茎数少,低产,中大茎,中等锤度;Ⅷ类包括1个材料,出苗一般,分蘖率高,大茎,成茎率不高,高产,中等锤度。【结论】云南湿润生态型甘蔗细茎野生种血缘的F1代创新种质材料同一类型的性状表现基本一致,而不同类型间表现出极大的差异。在云南湿润生态型细茎野生种创新利用研究中,针对性筛选利用不同类型种质材料的优良性状,可降低资源利用的盲目性,从而提高甘蔗细茎野生种资源育种效率。[Objective]This research classified the innovation germplasm materials of humid ecotype Saceharum spon- taneum L. F1 generation in Yunnan in order to provide scientific basis for improving the efficient utilization of Fj genera- tion innovation germplasm. [Method]By combining the theory of set pair analysis and the principle of fuzzy cluster, the iden- tical degree analysis method was used to classify the nine main traits of 20 germplasm accessions of humid eeotype Sac- charum spontaneum L. F1 generation in Yunnan. [Result]The 20 germplasm materials of Saecharum spontaneum L. F1 generation were divided into 8 categories： category I included one material with medium seedling rate, low tillering rate, low amounts of effective stalks, slender stalk, low yield, and low brix; category II included one material with high seedling rate and tillering rate, high amounts of effective stalks, high stalk rate, high yield, and high brix; category III, which accounted for 40% of the total number of materials, included 8 materials with medium seedling rate, medium amounts of effective stalks, large stalk, and medium yield; category IV included one material with normal seedling rate, large stalk, high yield, and low brix; category V included two materials with good seedling rate, medium tillering rate, high amounts of effective stalks, medium-large stalk, high yield, and relatively low brix ; category VI included 5 materials with good seedling rate, medium-small stalk, high yield, and medium brix; category VII included one material with low seedling rate, low amounts of effective stalks, low yield, medium-large stalk, and medium brix; lastly, category VIII in- eluded one material of normal seedling rate, high tillering rate, large stalk, low amounts of effective stalks, high yield, and medium brix. [Conclusion]Within the same category, the characteristics of Saceharum spontaneum L. F1 generation innovation germplasm materials were basically the same, but between different categories, the characteristic differences were signific
