摘要

We investigated the phylogenetic relationships among Citrus and its relatives, including 29 genotypes belonging to Citrus, Poncirus, Fortunella, Microcitrus, Eremocitrus, Atalantia and Severinia using AFLP analysis. Cluster analysis was conducted using neighbour joining (NJ) method. The results demonstrated that Poncirus, Microcitrus and Eremocitrus are distant from Citrus. A strong affiliation exists between C. halimii and Fortunella and the results did not support C. halimii as the fourth basic species. Further evidence was provided that P. polyandra should not be the hybrid between trifoliate orange and Citrus genotypes and it deserves species status. Neither the separation of subgenus Papeda and Citrus nor the separation of subgenus Archicitrus and Metacitrus were clearly resolved in the dendrogram. C. ichangesis is a distinct species very different from other Citrus genotypes, and the results showed it is improper to classify it into subgenus Metacitrus. C. reticulata, C. maxima and C. medica were separated into three distinct clusters. Therefore if only cultivated Citrus species are considered, the three basic species concept is acceptable. However, it is not applicable for whole genus Citrus.
