Accomplishments
Twenty research presentations were presented by university scientists, industry scientists, and graduate students on many topics related to corn breeding. In addition, for the first time, we had 7 posters presented during our poster presentation session. These presentations serve to facilitate the exchange of research information that normally would not get exchanged by this group at other meetings. The abstracts of many of these presentations can be found at:
http://corn2.agron.iastate.edu/NCR167/Abstracts/Default.html
The purpose of the uniform testing committees is to coordinate the evaluation of elite, unrelease germplasm at several locations in the U.S or Canada. The data gathered from these trials is invaluable in making release decisions on germplasm and allows us to obtain data on traits that individually we cannot obtain. These tests also foster communication and the exchange of germplasm
The uniform tests for the 100-300 maturity zone evaluated apppoximately 75 hybrids at 5 locations, the 400-600 maturity zone evaluated approximately 20 hybrids at 6 locations, and the 700-800 maturity zone evaluated approximately 25 hybrids at 8 locations.
The results of these tests are made available to the public and can be found at: http://corn2.agron.iastate.edu/NCR167/Station/2004/Default.html
Since the 2003 meeting, 36 inbred lines or synthetics were released by the members of the NCR167 regional group. This is an indication of the activity level of the breeding programs in the various states.
Similar meetings will be held on the University of Minnesota campus in 2005. The group has decided to meet on campuses for the next few meetings to that we spend some of the meeting actually visiting research programs.
The uniform tests of hybrids are being evaluated again in 2004 and hybrids for the 2005 growing season are being produced in 2004 summer nurseries.

Impacts
- Approximately 60 scientists attended the meetings to either share their research or learn what others are doing in their research
- The collection of high quality data facilites the release of inbred lines and gives seed companies, universities, and growers an early glimpse of the germplasm in the university piplines
- The release of inbred lines is one of the ulitmate impacts from public breeding programs. Their ultimate impact can be determined by the number of licenses of these lines that get established.
