Investigation of yield traits and medicinal components of Andrographis paniculata germplasm
(Burm.f.)Nees is a traditional medicinal material and is widely used in China. In order to evaluate the genetic diversity of
Andrographis paniculata
germplasm, this study collected germplasm materials from two main producing areas in Zhanjiang, Guangdong and Guigang, Guangxi, and then investigated their yield traits and main medicinal components. The results showed that the yield characters and medicinal components of
Andrographis paniculata
from the same source showed great variation. Among the yield traits, the maximum variation of biomass per plant was 100~624 g, and the remaining coefficients of variation were leaf weight, leaf area, number of primary branches, growth period, and plant height in descending order. Among the properties of medicinal components, andrographolide has the largest range of 1.538 5~6.594 4 mg/g, and the rest are neoandrographolide, 14-deoxyandrographolide, and deoxyandrographolide. The analysis of the tested materials found that the germplasm was poor in purity and degree, and had significant genetic diversity, which provided a rich material basis for material selection and genetic breeding. In addition, the correlation analysis showed that the main yield traits of
Andrographis paniculata
were significantly negatively correlated with the content of the main medicinal components. During material selection, attention should be paid to the balance between yield traits and medicinal components. Finally, further cluster analysis was carried out according to yield traits and medicinal components to screen important materials. The results of this study provide a breeding research material basis for the protection of germplasm resources of
