The aim was to investigate the genetic relationship between a new introduced germplasm(Salvia hispanica L.) and other two common members of Salvia L.family(Salvia splendens Ker-Gawler and Salvia farinacea),and provide the theoretic foundation for distant hybridization and genetic improvement in these three germplasms.In cytogenetics level,karyotypes of Salvia hispanica L.,Salvia splendens Ker-Gawler and Salvia farinacea were discussed in this paper.The results showed that chromosome number of normal diploid of Salvia hispanica L.was 2n=12,k...
