Abstract

Objective: To study the growth characteristics of different germplasm and analyze the correlation between morphologic and individual yield of Isatis 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. 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.

Conclusion: 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.
