Conteúdo: | The RAPD technique was used to identify genetic relationships in 19 accessions, including six species of the genus Chenopodium. A dendrogram was constructed using UPGMA from 399 DNA markers. The molecular data clustered species and accessions into five different groups. Group 1 with three cultivated varieties of C. nuttalliae, Group 2 included eight cultivars and two wild varieties of C. quinoa, Group 3 with C. berlandieri and C. album, Group 4 with two accessions of C. pallidicaule, and Group 5 with 2 accessions of C. ambrosioides. The polymorphic patterns generated by RAPD profiles showed diffferent deggrees of genetic relationship among the species studied. A low level of intraspecific variation was found within the accessions of C. quinoa, C. nuttalliae, and C. pallidicaule. The RAPD markers were found to be a useful tool for detecting genetic variation within the genus Chenopodium.
