Phylogenic Relationship of Allium Species in Subgenus Rhizirideum by PCR DNA Fingerprint

Allium is one of the largest genera, which has more than 700 species. PCR by URP (universal rice primer) primers was carried out to get phylogenetic information on 26 species, 62 accessions of subgenus Rhizirideum. The accessions were divided into seven groups at 0.76 similarity level. A. tuberosum (Chinese chives) and A. ramosum represented high similarity of 0.91. A. montanum, A. nutans, A. senescens, A. libani, A. odorum, A. austrosibiricum, and A. narcissiflorium grouped at 0.80 similarity. Some of the wild species, such as A. prostratum, A. polyrhizum, A. odorum, and A. mongolicum, showed different band patterns according to polyploidy, occurrence of B-chromosome, collection site, and origin.
