GEM FIELD DAY
In conjunction with the CAD Field Day at the Uthe Farm
September 18, 2002
The Germplasm Enhancement of Maize (GEM) Project is a cooperative effort of the United States
Department of Agriculture’s Agricultural Research Service, land-grant universities, private industry,
international, and non-governmental organizations. The mission of the project is to broaden the
genetic base of maize germplasm, increasing its diversity through introgression of unique and novel
germplasm into elite, adapted lines. The GEM Project is administered through the USDA-ARS’s
Plant Introduction Research unit in Ames, IA.
Breeding with exotic germplasm requires extensive, long term application of resources for nursery,
yield trial, and laboratory analyses. Most importantly, exotic germplasm should be adequately
evaluated and carefully chosen for introgression into elite, adapted germplasm. Effective, efficient
breeding strategies and processes are essential for success. The Latin American Maize Project
(LAMP) funded by Pioneer Hi-Bred Int’l., Inc. during the 1980’s successfully identified the best
exotic germplasm from over 12,000 populations or accessions. LAMP identified 268 elite
populations that provided the starting exotic material of GEM. “In kind” support from the GEM
cooperators includes (i) donation of elite proprietary germplasm by crossing to GEM accessions, (ii)
assistance by providing nursery space and breeding support, (iii) yield trial locations, and other
support such as lab analyses, disease and insect screening, etc. Research projects conducted by
GEM’s cooperators at the Universities are instrumental in generating the knowledge base for
working with exotic germplasm. On going research includes the identification of favorable QTL’s
from exotic sources, insect and disease resistance, value added grain traits, silage traits, and
development of optimal breeding methods.
The 2002 GEM Field Day observation plots demonstrate the breeding material (temperate and
tropical exotics) which has been developed and used at Ames (plots 21-50; 71-100), and at Raleigh,
NC (plots 113-138). The NC State material is from Dr. Major Goodman’s program, and consists
primarily of 50% tropically derived material. Good progress has been achieved in the development
of germplasm with value added traits (VAT) that include high oil, protein, and starch quality. Plots
51-70 include some of the VAT germplasm developed by Dr. Linda Pollak’s quality traits breeding
program. The most recent addition to the GEM Project cooperator group is the popcorn breeding
project and its cooperators. The “POPGEM” effort is coordinated by Ken Ziegler of Iowa State
University; plots 101-112 include popcorn material under population improvement with exotic
germplasm.
More information on the structure and organization of the GEM Project, yield trial results, GEM
accomplishments, and summaries of University research with GEM germplasm found in the Public
Cooperator’s Reports can be found on our web site, http://www.public.iastate.edu/~usda-gem/.
