摘要(Abstract):

目的:综合比较、评价四川盆地麦冬种质资源质量。方法:采用SPSS 17.0软件对来源于四川盆地不同产地的24个野生麦冬资源的主要化学成分及产量性状进行主成分分析及聚类分析。结果:资阳市市中区、资阳市简阳市、乐山市市中区a、宜宾市南溪县、重庆市涪陵区b、绵阳市三台县b等6个样品的综合质量评价值较高,其中以资阳市市中区样品对川产麦冬种质资源的贡献度最大,达州市大竹县样品的贡献度最小,主成分分析与聚类分析结果类似。结论:通过主成分聚类分析对麦冬质量进行综合评价的方法,具有可靠性;四川盆地麦冬野生资源丰富,可从中选择优质资源,为麦冬品种选育工作服务。
Objective: To compare and appraise the quality of germplasm resource of Ophiopogon japonicus in Sichuan basin.Method: According to the main contents and yield traits,24 wild germplasm resources of O.japonicus from different areas of Sichuan basin were comprehensively compared by the SPSS 17.0 software with principal component analysis and cluster analysis.Result: The six samples of Ziyang,Jianyang,Leshan,Yibin,Chongqing,Mianyang,their comprehensive evaluation value of quality were higher than the others,and the sample of Ziyang had the best quality,the sample of Dazhou had the least quality,the results of the cluster analysis to raw data were also shown a similar results as principal component analysis.Conclusion: The wild resources of O.japonicus in Sichuan basin is rich,there are much differences among their quality;the method,through principal component analysis to study the comprehensive evaluation of the O.japonicus quality,is reliability and the results of cluster analysis is also support the conclusions,it could be able to provide a reference to select high O.japonicus quality resources.
