Molecular diversity in the Indian Chenopod (Chenopodium album) as revealed by DNA-based markers

Published on

Population structure of 41 accessions of Chenopodium
album and its sub species C. album ssp. amaranticolor
along with five accessions of C. quinoa from India, USA
and Argentina was studied using 37 polymorphic
microsatellite loci. The C. album from India was highly
diverse and comprised of three distinct populations.The
first population was genetically similar to C. album, the
second was different from C. album as well as from C.
quinoa, whereas the third population resembled C. quinoa.
On the other hand, the ssp. amranticolor was genetically
similar to C. album. The RAPD markers delineated an
accession of C. quinoa into a separate group, whereas
SSR markers showed this accession to be genetically
similar to C. album. Genetic diversity patterns suggested
the need for taxonomic review of the Indian accessions
classified as C. album and C. album ssp. amaranticolor.
