MINUTES OF THE WHEAT CROP GERMPLASM COMMITTEE
9 December, 2002.
Cincinnati, OH, USA.
Committee members present: Olin Anderson, Harold Bockelman, Kim
Campbell (Chair), Elias Elias, Carl Griffey, David Marshall (Secretary),
Anne McKendry, Jackie Rudd, and Kay Simmons. Also present were
Jim Anderson, Joseph Anderson, Mark Bohning, Robert Bowden, Bikram
Gill, Yue Jin, and David Van Sanford.
Chairperson Kim Campbell convened the meeting at approximately
1:30 PM. The minutes of the January 2002 meeting in Orlando, FL,
were submitted and accepted by voice acclamation. The minutes
were published in the 2002 Annual Wheat Newsletter (48:4-6) and
also distributed previously via E-mail to committee members. Members
of the Wheat CGC are Kim Campbell, Carl Griffey, Gina Brown-Guedira,
David Marshall, Anne McKendry, John Moffat, Jackie Rudd, and Brian
Steffenson. Ex-officio members include USDAARS curator of
the National Small Grains Collection (Harold Bockelman), USDAARS
National Program Leader in Grains (Kay Simmons); CIMMYT representative
(Bent Skovmand); and a Canadian representative (vacant).
A brief history of the Wheat CGC presented by Kim Campbell
indicated the former name of the committee (Wheat Crop Advisory
Committee) and pointed-out that the objective of the Committee
was to serve in an advisory capacity to national wheat (and related
species) germ plasm efforts in the collection, cataloguing, preservation,
funding priorities, germ plasm enhancement, and open exchange
of germ plasm.
Harold Bockelman, curator of the USDAARS National Small
Grains Germplasm Collection distributed information concerning
the collection during 2002. The PI number assignments for all
wheat, rye, triticale, and Aegilops accessions were disseminated.
There are presently greater than 54,000 accessions of wheat and
wheat relatives in the collection. Discussion followed on the
electronic availability of information in GRIN (Germplasm Resources
Information Network) versus seed available for distribution. Mark
Bohning (GRIN Database Management Unit) discussed plans underway
to modernize the visual appearance of the GRIN website (http://www.ars-grin.gov/),
including a shopping-cart approach for ordering seed, a downloadable
format for trait files; and links to Crop Science registration
articles. Discussion followed on the need to access data on GRIN
accessions regardless of their seed availability.
Anne McKendry (University of Missouri) expressed concern over
the maintenance, storage, and availability of lines that had been
selected for Fusarium head blight resistance and subsequently
purified, which had been derived from heterogeneous accessions
in the National Plant Germplasm Collection. A motion was made
by Carl Griffey (Virginia Tech) stating that selections made for
Fusarium head blight resistance in heterogeneous germ plasm lines
should be purified, increased, and be made available for evaluation
in uniform nurseries and entered into the USDA Small Grains Collection.
The motion was second by Kim Campbell.
Olin Anderson (USDAARS) gave an update on the wheat genomic
data in GrainGenes. A committee has been formed to review the
wheat genomic database, with emphasis on making the information
more usable for researchers.
Kim Campbell gave a synopsis of the Crop Germplasm Committees
Chairperson meeting. The National germ plasm system has been greatly
expanded and improved in the past 10 years. Approximately USD
3-4 million was proposed by the administration for germ plasm
activities in the FY03 budget. At the meeting, additional topics
that were discussed included the need to have phytosanitary certificates
for all plant material entering the U.S.A., the status of molecular
evaluations on plant germ plasm, and the availability of interfacing
geographic information systems with germ plasm information.
Mark Dahmer (BASF Corp) presented an overview of the Clearfield¨
wheat technology. He indicated that the genetics and herbicide
(imidazolinone) combination is focused on wheat, canola, corn,
rice, and sunflower in the U.S.A. The herbicide-resistance trait
(FS4) was developed via mutagenesis and is, therefore, not a GMO
technology. The key to developing wheat cultivars having resistance
to imidazolinone is in partnership with university programs and
private breeding companies to breed the FS4 trait into adapted
Kim Campbell led a discussion of germ plasm collection proposals
and priorities. One approved collection trip was for wild wheat
and barley in Kazakhstan. A suggestion was made by Elias Elias
(North Dakota State University) for a collection in Armenia. Discussion
followed on areas needing collection; a suggestion was made to
develop a subcommittee to set priority areas for germ plasm collections.
Bikram Gill stressed the need for coördination in the
wheat community of work on molecular markers. Goals and objectives
for molecular-marker technology and mapping and association analyses
need to be realized and perhaps coördinated through the current
and proposed USDAARS Regional Genotyping Labs.
Committee members present: Harold Bockelman, Kim Campbell (Chair),
Elias Elias, Carl Griffey, David Marshall (Secretary), Jackie
Rudd, and Kay Simmons. Also present: Joseph Anderson, Mark Bohning,
Robert Bowden, Bikram Gill, Yue Jin, Akos Mesterhazy, Radney Pandeya,
and David Van Sanford.
Sally Metz (Monsanto Corp.) gave a presentation on germ plasm
issues associated with Roundup Ready wheat. USDA approval for
the technology is anticipated in the first quarter of 2005 in
spring wheat. Signed agreements between Monsanto and coöperators
are required for evaluation of Roundup Ready¨ wheat.
The remainder of the session focused on setting research priorities
for the evaluation of the USDAARS wheat germ plasm collection.
Disease and insect resistance, quality traits, and reaction to
abiotic stresses were all discussed and prioritized in terms of
need and expertise to collect the data. Brian Steffenson requested
approval to continue his evaluation of wild wheat and barley species.
The types of evaluations are unclear. There was no opposition
to his request.
The meeting concluded at approximately 10:30 PM., 9 December,
