Distribution and Maintenance of Amaranth Germplasm Worldwide

  • Saubhik Das


Proper collection, maintenance and periodical evaluation of crop germplasms are prerequisite for their involvement in any breeding program. Amaranth germplasm collections are maintained in at least 61 collection centers worldwide, prominent among them are Rodale Research Center (RRC), Pensylvania, USDA Plant Introduction Center at Ames, Iowa, National Bureau of Plant Genetic Resources (NBPGR), New Delhi etc. USDA, Ames, Iowa, USA published an amaranth catalogue of 2783 collections in 1990. Extensive, well-documented amaranth germplasm characterization has been conducted by organizations in India, Peru and Mexico. Since 1982. The collected amaranth germplasm in NBPGR includes nearly 2722 indigenous accessions and 293 exotic accessions. Now the total amaranth germplasm collection at Shimla, regional station of NBPGR is 3081 comprising mainly grain amaranth. Several promising improved breeding lines or cultivars have been released using both indigenous and exotic germplasm collections. Amaranth genome may serve as a model system to study weediness. Shot-gun sequence data from A. tuberculatus and recombinant lines (RIL) derived from initial crop-weed hybrids between A. hypochondriacus and A. hybridus can also be very useful for development of amaranth genetic map. A Bacterial Artificial Chromosome (BAC) library was constructed from A. hypochondriacus and Microsatellite markers developed from A. hypochondriacus and A. tuberculatus would be valuable for more detailed phylogenetic study and breeding efforts.
