CSREES REPRESENTATIVE - Mitch Woodward
ADMINISTRATIVE ADVISOR - Vance Watson, Mississippi State U.
REGISTRATION DESK - Debra Ahrent, U. of Arkansas
Fogleman opened our meeting, gave some details of meeting for the afternoon and presided during our afternoon meeting. Bernie White, Mississippi State variety testing, brought greetings from Vance Watson. Dr. Watson was in Jackson, MS appearing on behalf of Mississippi State AES in the state budget process.
Dr. Watson has kindly organized a WWW site at Mississippi State U. on which information for the group has been entered. Information includes officers, advisors, meeting date(s) when determined, minutes, history, publications, discussion groups and directory of variety test personnel. Check the URL below to see how it has developed and progressed as the 1998 information is included.
The group further indicated a desire to put operative information as to application dates, check varieties, and dates such as return of preliminary data to cooperators. Dewey Barefield of Clemson has developed a list server for discussions and exchanges. URL for the site is:
Go to the site to subscribe to the list server. At present eight states are online with variety performance data. Illinois is included and their participation is welcome as information is delivered.
Minutes for 1997 were approved. Minutes for 1997 and 1998 will be submitted to the SRIEG-33 web site (http://www.aac.msstate.edu/mafes/admin/ieg.html).
Those present from various companies and AES reported on new varieties and personnel changes.
Bob Harville, LSU, has kept our directory for the duration of SRIEG -33. He will continue to update the directory. All present were asked to make any changes known and in particular an e-mail address was requested. Contact via e-mail is quick, inexpensive, and generally satisfying. Updated directory will be available on line at the Mississippi site. The group once again expressed our thanks and appreciation to Bob for his efforts and good works.
Depicting data in a structured presentation setting and the presentation options were explored. Variety stability indications to growers were an objective. Various methods were presented including the Finlay and Wilkinson. Most methods are descriptive of variety performance opposed to predictive. Missouri tends to use two-year summaries in yield publication materials.
Presentation is an outgrowth of exploring ways to present data to growers and agents that would be most beneficial and still observe good statistical practices. A series of slides for barley, early and medium cotton, early, medium and full season corn, soybeans, and wheat were presented comparing presenting data as one or two-year means with probability of selecting high variety based on the data. Some of combinations included significant VY, VL, and or VYL interactions. Three-year data were not suitable because varieties tend to change too much over that time span. Based on examination of data in this manner North Carolina will not include any one-year/one-location data for farmers.
Valid reasons for discarding low-yielding tests were listed as (1.) Minimize differences between cultivars, (2.) Low ratio of LSD to range, and (3.) Concern about changes in relative performance of varieties. Bowman used a series of slides depicting regression analyses for varieties in high and low environments. He gave evidence that eliminating low-yielding trial does not always increase rank correlation test and that one cannot always show a reason for discarding low-yielding tests.
Analyses of GXE interaction was presented as cluster analysis and principal components. Similar environments can be grouped together with small GXE. Examples were given with soybeans. Mega-environments were described as a set of E with little GXE with an eye toward recommending varieties by mega-enviroments.
Another possible approach with multivariate analyses is Principal Components AMMI. Data was presented from soybean yield trials in Arkansas where locations could be clustered by GXE patterns. Sneller considers the AMMI approach to GXE as a work in progress and holding promise for analyses and understanding GXE.
Each person spoke briefly about herbicide-resistant crops. Two views exist: RR varieties in a test by themselves; and all soybeans entered into one test. General view was that in time RR varieties would be entered in standard tests. In a transition period four states do not have a separate test while others did have separate tests. Many and varied comments from the floor during discussion reflected a diversity of thoughts and approaches.
In 1970 Monsanto received registration of Genesis, a sterilizing agent for wheat. They now have the ability to make and test best combinations between inbred lines. Line of hybrids will be called Quantum. In the USA 16 hybrid varieties will be released. Across Europe nine hybrids will be released. Data was presented for superior yield and stability for some hybrids. HybriTech also sees the hybrids as a platform for biotechnology added gene or genes. In 1997 300,000 acres of hybrids were planted in the US and France. Acreage growth is expected.
High oil is a collaboration with DuPont and Pioneer and called Optimum, a trademarked product. Higher oil content for animal feeds is the main selling point and a ready domestic and foreign market has been developed. The high oil corns are topcrosses and pose some problems when entered in conventional variety tests. Primary problem is keeping high oil due to pollination by conventional hybrids. At present 70 seed companies are testing and selling seed. These company tests are elaborate efforts to account for pollination and not readily adapted to university tests. Some discussion about how testing could be adapted to conventional test was offered and the problem will continued to be addressed by Holden's Seeds and corn variety test personnel.
The Optimum High Oil Corn program is in its second year in 1998. In 1997 200,000 bushels were produced on 600 acres. In 1998 some 1800 plus acres are planned. Product needs 7% oil, good grain quality (#2 yellow corn) and a constant supply that primarily goes to 3rd world countries. Contract grower benefits are increased revenue per acre.
Grower is paid 20 cents bushel over the market price for 7 percent oil corn. Contract acreage is in Arkansas, Mississippi, Missouri, Kentucky, Tennessee, and South Carolina. Continental grain in the process of developing contracts with farmers to grow high oil corn needs unbiased yield data from universities. Demand is high for yield data as she develops, contracts, and supplies growers with information.
Following was noted about high oil corn (HOC). 2/3 of HOC will be fed in the USA, replacement value of fat is worth $0.35, HOC is easier to use in making rations, and HOC has easier digestibility. HOC is first in a series of value added traits (VAT) planned by Optimum. They have HOC + oleic, HOC + high lysine, lysine + methionine, and high phosphorus products that will be phased in over a period of years. They plan a series of programmable grain depending on needs and sales. A video tape is available as well as brochures.
Harrison indicated that he sent out a short report of varieties that allowed checking of names before final publication.
This proposal of preliminary yields strongly reinforces the need for email addresses in the Directory of SRIEG-33.

Described three equipment items that are available from him for use in either variety testing or breeding projects.
Contact Milton McDaniel, Soil and Crop Science Dept, College Station, Texas 77843-2474 for details of above items. Equipment items are being developed as a product line.
Director Watson and his staff at Mississippi have created a web page for SRIEG-33 at the following URL:
This is the first IREG with web site for accessing our information. The SRIEG-33 group extends a hearty thanks to Director Watson and Ms. Patsy Sykes for the efforts on our behalf.
Initial hot links are Officers and Advisors, Meeting Dates, Minutes, History, Publications, Discussion Group, and Directory of Variety Testing Personnel. Another item planned was a link to the various operating principles of SRIEG-33 such as dates for sending out applications, check varieties, and statistical measures agreed to by the group (Bowman).
Minutes of 1997 were approved. Minutes were mailed to 1997 participants by Harville. Minutes are also listed on the SRIEG-33 web page.

Co-chairs Raymer and Fogleman provided excellent leadership and service with respect to finances and the group offers our thanks.
SRIEG-33 and co-chairs extend a special thanks to Debra Ahrent, Jerry Nail, and Garland Veasey for their assistance at registration and the social function on Tuesday.
Recipient of the 1998 Service Award is Dr. Daryl Bowman. Daryl is a SRIEG-33 founder, continuing leader, source of thought-provoking presentations and innovative approaches to variety testing and information delivery. SRIEG-33 owes much to him for our success and feel that he is a most worthy choice. Daryl, the pleasure is ours in presenting you this award.
The members of SRIEG-33 wish to express our appreciation and commendation to Joe E. Askew of Mississippi State University (retired) for his many contributions to our group.
Joe has been a faithful member who has given freely of time and expertise. He has given numerous presentations over the years and has been an organizer and "keeper of the gate" for corn and soybean check varieties.
Joe served as co-chair of our group in 1989, served on several nominating committees, and assisted in recruiting speakers for our meetings.
In that he has done all of these things cheerfully, helpfully, and with a sense of service to the group, let us vote to send a copy of this missive to express the appreciation of SRIEG-33 to Joe E. Askew, good and faithful member.
