Abstract：Objective: To evaluate the stability and adaptation of single root weight and active compounds content of hybrid Salvia miltiorrhiza Bge F1 lines. Method: We applied GGE-biplot to analyze the stability of yield and quality traits, and representativeness and discrimination of testing site, with 5 F1 hybrid lines and 2 production germplasm planted in four different testing sites. Result: H4 had better performance and stability at yield and salvianolic acid B content in Beijing-haidian; H4 and H16 had better performance and stability at yield and active compounds content in Beijing-miyun; H24 had better performance and stability at yield and active compounds content in Shanxi-shangluo; H24 had better performance and stability at yield and lipophilic ingredients content in Henan-fangcheng. The breeding region and selection region of Salvia miltiorrhiza Bge F1 lines could modified through the analysis of testing site's representativeness and discrimination. Through the analysis of testing site's representativeness, we could determine the breeding region of Salvia miltiorrhiza Bge: Beijing-haidian and Henan-fangcheng had better representativeness at salvianolic acid B and lipophilic ingredients content, respectively. When planted in Beijing-miyun cultivars with low yield could be eliminated, while Henan-fangcheng and Shanxi-shangluo could eliminate cultivar with low lipophilic ingredients content. Conclusion: GGE-biplot was a rational method for stability and adaptation evaluation of Salvia miltiorrhiza F1 lines, and could assist us to select good culture and suitable test site. It provide scientific basis for the establishment of breeding site and selection site of Salvia miltiorrhiza.
