To study the growth characteristics of different germplasm and analyze the correlation between morphologic and individual yield of Isatis indigotica.
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.
The growth characteristics of various I. indigotica 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.
The number of leaves per plant and root length are selected for high-yield lines, meanwhile, leaf length and leaf diameter are important factors for breeding high-yield lines as well.
研究不同种质菘蓝的生长特性，分析菘蓝形态特征与单株产量之间的相关性。
在生长期间采集种植样本，对来自全国各地的13份菘蓝种质的形态特征和单株根产量进行测定，并进行相关性和通径分析。
各菘蓝种质的生长特性一致。不同种质间形态特征和根产量差异显著。单株根产量与主根长度和单株叶片数呈正相关。
选择单株叶片数和根长用于高产株系选育，同时，叶长和叶直径也是选育高产株系的重要因素。
