National Arid Land Plant Genetic Resources Unit (NALPGRU)

ABOUT US:

The National Arid Land Plant Genetic Resources Unit (NALPGRU) serves as an important germplasm regeneration center for other National Plant Germplasm System (NPGS) sites that have species and accessions that require long frost-free seasons or arid conditions for seed production or regeneration of vegetative propagules. Among the most important climate specific germplasm regenerated at Parlier yearly for other NPGS sites are accessions of non-winter hardy Hordeum, Triticum, Secale, Allium sativum (garlic) and wild Helianthus.  Crops received for regeneration less regularly are Capsicum, Lupinus, Petroselinum crispum, Allium, Cucurbita, Cuminum cyminum, and Carthamus.  A back up collection of Corylus is maintained for the National Clonal Germplasm Repository (NCGR), Corvallis, OR. 

In addition, the National Arid Land Plant Genetic Resource Unit (NALPGRU) in Parlier, CA is the priority site for conservation of arid land plant species with potential as industrial crops, including the genera Simmondsia, Limnanthes, Physaria/Paysonia, Parthenium, and Opuntia.  These genetic resources are acquired, conserved, characterized, and distributed to scientists worldwide.

The incumbent serves as the Arid Land Plant Germplasm Curator and NPGS long season seed increse specialist at the NALPGRU, which is a worksite of the National Clonal Germplasm Repository (NCGR) for Tree Fruits and Nut Crops and Grapes located in Davis, California.

MISSION:

The mission of the National Arid Land Plant Genetic Resource Unit (NALPGRU) program is to acquire, document, maintain, evaluate and distribute selected plant genetic resources adapted to long, warm-season and arid conditions, generate and manage associated information, provide a scientific base for its use in research and crop improvement and collaborate with other scientists in research programs incorporating the scientific information in agricultural production.

HISTORY:

Established in 1996, the station serves as an alternative regeneration site for long frost-free growing season. It is a priority site for genera of arid land plant species, which are emerging as new industrial crops (Lesquerella, Limnanthes, Opuntia, Parthenium and Simmondsia) or have the potential to be developed into cash crops on poor soils with limited water supply (Hesperaloe), or present a value to arid land soil preservation (Atriplex, Bassia and Yucca). Currently, the holdings of the site include over 1,200 accessions, belonging to 126 different species, from 13 different genera. Among the most important climate specific germplasm preserved at Parlier for other NPGS sites are accessions of non-winter hardy barley (Hordeum sp.) and wheat (Triticum sp.), wild sunflowers (Helianthus sp.), safflowers (Carthamus tinctorius) and a core back up collection of hazelnuts (Corylus sp.).
