不同生态型大白菜主要产量性状的相关和通径分析

本文对三一态型大白菜的９种主要产量性状进行了相关和通径分析。结果表明，不同生态型大白菜的同一性状对单析产量的影响有很大区别，且对三种生态型单株，产量贡献最大的性状各不相同，因此对不同生态型大白菜进行单株选择时应予以分别考虑。

Relativity Among the Main Output Traits of Different Ecophenotype Chinese Cabbages and Path Analysis

Results showed that in breeding high individual plant output of different ecophenotype Chinese cabbages,different traits should be taken into account respectively.Head diamter played an important role in selection of high type, on the basis of analysis of correlation and path coefficients. Stem/leaf of externally central leaf and number of central leaf were the main traits determining the individual plant output of cylindrical type. Selection of oval type should be carried out mainly on the basis of gross weight.
