Phylogenetic analyses of DNA sequences of four plastid regions, nrITS and nuclear 5S rDNA Revised 1 April 2016 spacer region (NTS) of two tetraploid chenopods (2n =4x = 36), Andean C. quinoa and North American C. Accepted 6 April 2016 berlandieri, and their diploid relatives allowed inferences of their origin. The phylogenetic analyses Available online 7 April 2016 conﬁrmed allotetraploid origin of both tetraploids involving diploids of two different genomic groups (genomes A and B) and suggested that these two might share very similar parentage.
