ABSTRACT
The supply deficiency of crude medicinal plant of Paris polyphylla var. chinensis has become a bottleneck for related medicinal industry. An important approach to increase herbal production is to breed high-yield cultivated variety, which characterized ideal plant morphology. In the present study, we collected 99 wild germplasm resources of P. polyphylla and then measured their 12 main agronomic traits and contents of polyphyllin â

. Followed analyses were used to characterize those traits and explore the potential connection with herbal yield or quality. The results showed that â There was ample morphological diversity in wild P. polyphylla, whose variation of agronomic traits reduced according to followed order content of polyphyllin, weight of dry rhizome, petiole length, stem length, petal length, pedicel length, sepal length, leaf width, leaf length, sepal width, leaf number, stamen number, petal number. â¡ Most of those traits were significantly correlated to each other and generally represented the characterization of photosynthetic organs or reproductive organ. â¢The total content of polyphyllin â

varied between 0.02% and 0.87% and averagedat 0.13%, which showed no significant correlation with any agronomic trait. â£Plant breeders should play more attention on those germplasm resources with large leaves, large sepals and high stem.
