Abstract: Fourteen Allium cultivars were analyzed by RAPD technique to determine their genetic relations. Of the 56 decamer primers screened , 18 showed consistent band pattern and amplification , and produced 270 bands with 246
polymorphic bands in the chloroplast genomes. The genetic distances among the materials ranged from 0 to 13. 2. Four sections were classified by UPGMA cluster analysis , which demonstrated that welsh onion chive and bunching onion should be divided into Fistulosum , bulb onion and shallot be clustered into Cepa , the others belong to Porrum and Rhiziridium. There might exist two directions in Allium evolution , pipy leaf type and flat leaf type of Allium were formed.
