摘要： The aim of the research was to discuss the genetic relationships among Piper methysticum, Pepper and it wild relatives. With 28 germplasms including 6 materials of P. methysticum, 21 materials of cultivated and wild pepper, 1 material of Peperomia pellucida belonged to different genus as tested materials, DNA was extracted from leaves and primers with good band-type and high polymorphism and resolving power were screened from 64 pairs of primers for AFLP amplification and the clustering analysis was conducted with MVSP3.13f software. 191 bands were amplified by 4 pairs of primers, 189 of which had polymorphism being 98.6%. 28 germplasms were clustered into 6 different groups at the genetic similarity coefficient of 0.52 by silver staining AFLP, in which 6 materials of Piper methysticum were clustered into a single group, indicating that P. methysticum belonged to Pipper L., Piperaceae and were distantly related to the others. The research provided the basis for selecting rootstocks, molecular identification and the fingerprint construction of P. methysticum.
