[Genotype, environment and their interactions of major bioactive components in 2-year licorice (Glycyrrhiza uralensis) population].
OBJECTIVE
This study aimed at analyzing the effect of genotype (G), environment (E) and their interactions (G x E) on the major bioactive components of 2-year licorice (Glycyrrhiza uralensis) population, in order to provide a theoretical basis for the licorice breeding with high content of bioactive components and quality improvement.


METHODS
Four genotype licorice populations were transplanted under four different environments by using complete randomized block design with three replicates, and four major bioactive components, including glycyrrhizin (GL), total saponins (TS), liquiritin (LQ) and total flavonoids (TF) were determined by UV and by HPLC.


RESULTS
The major bioactive components of licorice were influenced by genotype and environment, and the genotype had more effect on all of the bioactive components. The contents of GL and LQ were codetermined by genotype and environment factors.


CONCLUSIONS
There exist different selective effects on different growth region for quality breeding in cultivated population of licorice.
