摘要
目的:通过对菘蓝种质生长特性及其与单株产量相关性进行分析,明确构成菘蓝根及叶产量的关键性状,以期为菘蓝高产栽培及育种提供理论依据。方法:采用田间小区试验,定期采样测定,结合相关及通径分析方法对菘蓝种质主要形态学性状与单株产量的关系进行统计分析。结果:菘蓝种质生长特性基本趋于一致;以根长、单株叶片数对单株产量影响较大;各种质叶及根部产量存在一定差异。结论:对菘蓝种质进行丰产选育时,应重点考虑根长及单株叶片数,同时兼顾对叶长较长和叶宽较窄株系的选择。
Objective： To study the growth characteristics of different germplasm and analyze the correlation between morphologic and individual yield of lsatis indigotica. Method： The planting samples were collected during the growth period, morphological characteristics and root yield per plant in 13 germplasm of I. indigotica from all over the country were determined by correlation and path analysis. Result： The growth characteristics of various I. i.wligotica germplasm were consistent. The difference of morphological characteristics and root yield with various germplasm were significant. The root yield per plant was positively correlated to the main root length and the number of individual plant leaves. Conclusion： The number of leaves per plant and root length are selected for highyield lines, meanwhile, leaf length and leaf diameter are important factors for breeding high-yield lines as well.
