摘要:

综合评价浙麦冬不同种质资源的多样性,可为筛选其优异种质提供理论依据。本研究收集20份不同来源的浙麦冬材料,测定其12个主要农艺性状和4个品质性状,通过主成分分析与聚类分析进行系统评价。结果表明,各性状在种质间均存在变异,其中麦冬甲基黄烷酮B含量的变异系数最高(达151.48%),总黄酮含量与叶宽的变异系数相对较低。主成分分析提取出4个主成分,累计方差贡献率为83.091%,能够较好地表征16个性状。综合评价显示,来自浙江省慈溪市逍林镇(XL)、胜山镇(SS)和新浦镇(XP)的种质资源得分居前三位,可作为浙麦冬亲本选配的优良材料。与野生资源相比,农家种在长期栽培中形成了较优的性状组合,更适宜作为遗传育种的亲本,为今后浙麦冬种质资源利用与新品种选育提供参考。

Abstract:

Comprehensive evaluation of the diversity among different germplasm resources of Ophiopogon japonicus from Zhejiang can provide a theoretical basis for screening superior germplasms. In this study,20 materials of O. japonicus from different sources were collected,and 12 main agronomic traits along with 4 quality traits were measured. Systematic evaluation was conducted using principal component analysis(PCA)and cluster analysis. The results showed that variations existed among all traits across the germplasms,with the coefficient of variation(CV)for methylophiopogonanone B content being the highest(reaching 151.48%),while the CVs for total flavonoid content and leaf width were relatively low. PCA extracted four principal components,whose cumulative variance contribution rate reached 83.091%,effectively characterizing the 16 traits. The comprehensive evaluation indicated that germplasm resources from Xiaolin Town(XL),Shengshan Town(SS),and Xinpu Town(XP)in Cixi City,Zhejiang Province,ranked the top three in scores and can be used as excellent materials for parental selection in O. japonicus breeding. Compared with wild resources,local landraces have developed a more favorable combination of traits through long-term cultivation,making them more suitable as parents for genetic breeding. This study provides a reference for the future utilization of O. japonicus germplasm resources and the breeding of new varieties.

Key words: Ophiopogon japonicus, germplasm resource, principal component analysis, cluster analysis, comprehensive evaluation
