Abstract: Abstract: The correlations between biomass, active components and agronomic traits of different resources of Bergenia purpurascens in Yunnan province were explored for the first time. It was showed that there was a very significant positive correlation (P<0.01) between dry weight of rhizomes per plant, total dry weight of plant and plant height, diameter of rhizomes. A significant positive correlation (P<0.05) between dry weight of leaves per plant and plant height and a very significant positive correlation (P<0.01) between dry weight of leaves per plant and diameter of rhizomes per plant were found too. There also was a significant positive correlation (P<0.05) between the yield of bergenin per plant and diameter of rhizomes, although there was no significant correlation between the yield of bergenin per plant and other agronomic traits. No significant correlation between content of bergenin in the rhizomes, the yield of arbutin in the leaves and 7 agronomic traits was found. A significant negative correlation (P<0.05) between content of arbutin in the leaves and plant height was found. Although there was no significant negative correlation between content of arbutin in leaves and other agronomic traits, however, a significant negative correlation trend was found between them. Plant height and diameter of rhizomes are the two important agronomic traits for screening and breeding new varieties of B. purpurascens.
