摘要(Abstract):

目的:通过研究夏枯草形态学性状与单株产量间的关系,为夏枯草系统选育和规范化栽培提供理论依据。方法:采用田间小区试验,对来自全国15份夏枯草种质的形态学性状进行相关、通径及主成分分析。结果:夏枯草种质中6个形态学性状存在较大遗传变异;单株穗重与单株果穗数和单株叶鲜重呈极显著正相关,与穗长呈显著正相关;主成分分析结果表明,前3个主成分对变异的贡献率达87.533%。结论:在夏枯草丰产种质选育中应重点关注生长势强、单株果穗数较多及果穗较长的株系。
Objective:To study the correlation among the morphological characteristics and the spica yield of various germplasm of Prunella vulgaris.Method:The various P.vulgaris germplasm from all over the country were investigated by analysis of correlation analysis,path analysis and principle component analysis in a randomized block experiment.Result:The 6 morphological characteristics were greatly different from each other in various germplasm.The spica yield per plant had a very significantly positive correlation with the number of spica per plant and fresh leaves weight per plant,meanwhile the correlation between the spica yield per plant and spica length was very significantly.Three principal components which accounted for 87.533% of total variance were extracted from the principal component analysis.Conclusion:The strong growth potential,the number of spica per plant and spica length were main factors for the selection of high yield breeding of P.vulgaris.
