广西野生蕉种质资源调查与鉴定

【目的】较全面地收集并鉴定广西野生蕉种质资源的亲缘关系和分类地位,为广西野生蕉资源的保护和利用提供理论依据。【方法】采用染色体制片压片法、形态学分类法和荧光AFLP标记分别对广西境内的14份野生蕉种质进行染色体倍性、形态学分类和亲缘关系的鉴定与研究。【结果】形态学分类鉴定表明,供试的14份野生蕉种质资源染色体倍性均为二倍体,2n=22（x=11）。其中2份鉴定为M.acuminata subsp.malaccensis种,其余12份鉴定为M.itinerans种,种间形态学性状差异较大。基于AFLP标记的鉴定结果表明广西野生蕉资源具有丰富的遗传多样性,与形态学鉴定结果基本一致。【结论】供试的1...

Summary:【目的】较全面地收集并鉴定广西野生蕉种质资源的亲缘关系和分类地位,为广西野生蕉资源的保护和利用提供理论依据。【方法】采用染色体制片压片法、形态学分类法和荧光AFLP标记分别对广西境内的14份野生蕉种质进行染色体倍性、形态学分类和亲缘关系的鉴定与研究。【结果】形态学分类鉴定表明,供试的14份野生蕉种质资源染色体倍性均为二倍体,2n=22（x=11）。其中2份鉴定为M.acuminata subsp.malaccensis种,其余12份鉴定为M.itinerans种,种间形态学性状差异较大。基于AFLP标记的鉴定结果表明广西野生蕉资源具有丰富的遗传多样性,与形态学鉴定结果基本一致。【结论】供试的14份野生蕉均属于芭蕉属真蕉组（Eumusa）,其中2份归属为小果野蕉亚种,12份归属为阿宽蕉,该种在广西分布较普遍。AFLP鉴定结果显示广西野生蕉种质资源间遗传差异较大,与栽培蕉亲缘关系也较远。

[ Objective ] The wild Musa germplasms resources were roundly collected in Guangxi province and their genetic relationship and classification status were clarified to provide a theoretical basis for protection and utilization of the wild Musa germplasm. [ Method] Based on chromosome tabletting, morphological taxonomy and AFLP labeled with fluorescence methods, genetic relationship of 14 wild Musa germ- plasms from different regions in Guangxi Province were investigated and studied. [ Result ] The morphological identification showed that the chromosome ploidy of the 14 wild Musa germplasms were diploid, 2n = 22 （ x = 11 ）. 2 of them were identified as M. acumirtata subsp malac- censis, and other 12 were iden
