摘要：

Genetic relationships in 55 accessions belonging to 14 species of Chenopodium have been studied by RAPD and DAMD markers. A UPGMA dendrogram based on 242 DNA markers divided the taxa into two main clusters. The first cluster joins all the accessions of Chenopodium quinoa with Chenopodium berlandieri subsp. nuttalliae, one Chenopodium album (4x) from Mexico and three north Indian 2x accessions of C. album. The other clusters comprises mainly 6x accessions of C. album and Chenopodium giganteum forming two subclusters. This clearly shows that C. album complex is a heterogenous assemblage and its taxonomic affinities need reassessment. Other wild species placed in the dendrogram are more or less according to their taxonomic position.
