Abstract: Taking SCBH（Salvia miltiorrhiza f.albafound in Sichuan）as the research material,and SDC-1（S.miltiorrhizacultivated in Sichuan）,SDBH（S.miltiorrhizaf.albafrom Shandong）and SD（S.miltiorrhiza from Shandong）as the control materials,25traits of plant and root agronomic characters and main active ingredient contents of SCBH,CDS-1,SDBH,and SD were compared and cluster analyzed by statistical measurement,high-performance liquid chromatography（HPLC）,and unweighted pair-group method with arithmetic means（UPGMA）,in order to provide referene for the flower color variation in S.miltiorrhiza.The results showed that the phenotypic characteristics of SCBH were more similar to CDS-1,and significantly different from SD and SDBH.The clustering analysis results showed that there was smaller genetic distance between SCBH and CDS-1,indicated that SCBH was closely related to CDS-1.In contrast,whether the genetic distance between SCBH and SD or between SCBH and SDBH was bigger,suggested that the genetic relationship between SCBH and SD/SDBH was farther away.It was preliminarily speculated that SCBH might be a white flower mutant of CDS-1.
