The onion (Allium) collection, consists of more than 1200 different accessions.  Those accessions needing regeneration are chosen yearly by Dr. Larry Robertson, geneticist and vegetable crop curator.  Alliums are a biennial crop (needing 2 years to produce seed).  The short-day onion collection for the Plant Genetic Resources Unit is maintained by a partnership with New Mexico State University.
