Progress 07/01/98 to 12/31/03
Outputs
Commercial cultivars of corn, soybean, and grain sorghum were evaluated for yield and agronomic performance in central Louisiana during the course of this project. In the final year, 150 soybean varieties, 87 corn hybrids, and 38 grain sorghum hybrids were tested. Results were posted on the web to help Louisiana producers select the most profitable ones for production. LA 422 wheat and LA 495 Secretariate oat varieties were released from the small grains breeding program. Over 600 advanced soybean breeding lines with superior weathering resistance were screened over a 2-year period, from which about eighteen were selected for final screening and planned subsequent release. Good seed quality was maintained in superior lines despite three hurricane systems in 2002. The expectation is to release from one to three lines and to incorporate glyphosate resistance into at least one of these for commercial production. The distribution of aflatoxin was measured in several corn
populations. Harvested ears were rated for quality, fungal growth, bright greenish-yellow fluorescence, aflatoxin (ppb), and fumonisin (ppm). Inoculating with A. flavus greatly increased fungal growth, BGYF, and aflatoxin. Fungal growth and aflatoxin were greater in the susceptible line. Aflatoxin increased while fumonisin decreased when plants were self-pollinated. The correlation coefficients of aflatoxin with BGYF and fungal growth were 0.93 and 0.87, respectively. These results indicate that the rapid and inexpensive technique of measuring BGYF may be a useful tool, especially in coarse early screening trials. Fumonisin was not affected by any variable other than pollination method. There were no significant interactions between inbreds and inoculation or pollination methods. These results indicate that time-consuming self-pollinating techniques will not be necessary to assess resistance, and that inoculating with A. flavus spores to help insure a sufficient concentration of
aflatoxin for effective screening will not inhibit distinguishing superior lines with resistant genes. Contamination was related to ear size indicating the need to select ears of uniform size when screening for resistance. In breeding for resistance to aflatoxin biosynthesis, over 2700 corn breeding lines were screened for aflatoxin contamination in 2002 resulting in about 250 being selected and screened again in 2003. About 20 lines with superior resistance from the 2003 screening are being hybridized with Mo17 to screen for resistance and to determine breeding value in 2004.
Impacts
Performance data has helped producers choose profitable cultivars for production. Development of competitive soybean germplasm with weathering resistance is a significant step to help make available varieties that have vastly superior resistance to deterioration caused by late-season rains. If the corn germplasm now being tested has superior resistance to aflatoxin, then incorporating this resistance into commercial inbreds will help producers reduce devastating losses at the elevator.

Progress 01/01/02 to 12/31/02
Outputs
The three main objectives of the applied genetics research in this project are to: (1) Determine yield and agronomic performance of commercial corn, grain sorghum, and soybean varieties, (2) Improve resistance of corn to aflatoxin biosynthesis, and (3) Improve weathering resistance in soybean. Sixty-six corn hybrids were evaluated for yield and agronomic performance in seven environments. Highest yielding hybrids were identified at six of the locations and results were made available to producers. A second year of aflatoxin and fumonisin contamination was collected for corn hybrids at four locations. Hybrid resistance is being analyzed for publication at this time. Over 2500 experimental corn lines were planted and inoculated at Alexandria and are being screened for resistance to aflatoxin biosynthesis. Self-pollination and inoculation with Aspergillus flavus did not change the ranking of toxin contamination in two inbreds, providing hopeful evidence that these
techniques may be used to screen new germplasm without excessively changing resistance patterns. Over 600 advanced soybean lines were produced and are being screened for weathering resistance. Seed quality was shown to be high in a significant number of lines, despite weathering three hurricane systems. Superior lines will be tested in replicated plots in 2003, and hopefully, some lines may be released.
Impacts
Accurate information on cultivar yield and agronomic performance helps Louisiana farmers select the best cultivars for production. Choosing a hybrid with only a 3 to 4 bushel advantage adds about five million dollars of profit on a statewide basis. The number one production concern of corn producers is aflatoxin contamination. In some years millions of dollars are lost due to contamination. Hybrids with improved resistance help reduce this loss. In 2002, soybean losses to weathering were in the multi-millions of dollars. Providing farmers with resistant varieties may help save a great portion of this loss.

Progress 01/01/01 to 12/31/01
Outputs
The corn and soybean breeding program at the Dean Lee Research Station in Alexandria Louisiana has two primary goals: (1) Develop commercially viable hardseeded soybean cultivars, and (2) Develop commercially viable corn inbreds/hybrids with resistance to Aspergillus flavus and/or aflatoxin biosynthesis. The greatest progress in developing hardseeded soybean cultivars in 2001 centered on selecting out hardseeded lines from populations which were initiated mostly in 1995. Selection for yield, hardseededness, and agronomic characteristics had previously been done. Individual hard seed selected from populations were planted in the winter nursery in 2000-2001 and grown in 2001. The result is that over 500 lines will be evaluated for yield and hardseededness in the summer of 2002. We hope to identify the best lines for potential release. We also began backcrossing these lines with the glyphosate resistant variety 'Reznik' to transfer resistance. Significant progress has
been made in developing corn germplasm with potential resistance to Aspergillus flavus and/or aflatoxin biosynthesis. The breeding program at Alexandria requires two years to complete one breeding cycle. The first full breeding cycle will be completed in 2002 where over 4000 progeny rows from over 20 populations are scheduled to be screened for resistance. Lines which show resistance levels superior to those now available will be released as germplasm, and advanced for more improvement. Preliminary field research and logistical preparations are also being made in 2002 to begin screening worldwide collections of maize germplasm to identify new resistant genes.
Impacts
The development of weathering-resistant soybeans will help Louisiana producers avoid potentially millions of dollars of crop losses due to late-season rains that cause seed deterioration. Development of commercially viable corn inbreds with resistance to Aspergillus flavus and/or aflatoxin biosynthesis will help Louisiana producers avoid potentially millions of dollars of crop loss due to aflatoxin contaminated corn that may occur especially in hot and dry seasons.

Progress 01/01/00 to 12/31/00
Outputs
This project includes breeding efforts to reduce aflatoxin in corn, to reduce weathering in soybeans, and to evaluate performance of commercial corn, grain sorghum, and soybean cultivars. F1 seed were harvested from over twenty crosses with at least one parent heralding resistance to Aspergillus flavus and/or aflatoxin biosynthesis in 2000. Seed were planted in a winter nursery to advance generations. Individual ears from segregating F2 plants from two populations initiated in 1999 were inoculated and screened for fungal growth and aflatoxin. Laboratory results indicated that ears could be pre-screened for aflatoxin using bright greenish-yellow fluorescence (BGYF) which may help reduce samples needing analyses by 80% or more. An advanced yield tests in soybeans resulted in the identification of numerous experimental lines to be on par with elite checks. Individual plant selections were made from advanced soybean lines in order to improve plant height and seed yield.
Hard seed were screened in bulk soaks for advanced lines having a hardseeded parent. Plants are being produced in a winter nursery and are to be evaluated for yield and weathering resistance in 2001. Soybean crosses between elite cultivars and a hardseeded line were made in 2000 and a generation advance is being made in a winter nursery. Commercial variety performance tests were conducted in corn, grain sorghum, and soybeans in 2000, including evaluation of cultivars with transgenic traits. Results from these tests are being used to recommend varieties to growers. Oat and wheat breeders seed were produced in 2000 in support of the Louisiana Agricultural Experiment Station's small grains breeding program. One wheat cultivar (Secretariate LA422) is being released for commercial production.
Impacts
The future of corn production in Louisiana and the Southeastern U.S. may be significantly affected by the development of resistance to Aspergillus flavus and/or aflatoxin biosynthesis. Development of weathering resistance in soybeans will help to reduce quality loss when harvest is delayed due to wet weather.

Progress 01/01/99 to 12/31/99
Outputs
Project LAB03351 focuses on breeding objectives and variety testing in agronomic field crops. A corn breeding program with the primary objective to transfer resistance to aspergillus flavus and/or aflatoxin production to inbred lines was initiated in 1999. Agronomic characteristics were recorded for resistant lines and inbreds in 1999 and seed were increased. Crosses were initiated in the summer and F1 seed were produced in a winter greenhouse. Seed from F1 plants are now approaching harvest and will be planted for screening in 2000. Advanced lines from a soybean improvement program had good yields in 1999 and will be grown in the commercial soybean variety test in 2000. New crosses were initiated between elite varieties, a hardseeded line, and a herbicide-resistant line. The seed were planted in a winter greenhouse and most F2 seed have been harvested for progeny row production in 2000. The release of an oat line was published in 1999. Crop variety tests for corn,
cotton, grain sorghum, oat, soybean, and wheat were conducted. The corn test was lost due to high winds which produced excessive lodging. Data from the other tests have been or are being published and distributed to producers to help in selecting profitable varieties for production.
Impacts
Aflatoxin in corn and weathering in soybean have devestated these crops in Louisiana in previous years. Competitive varieties with resistance to these factors will help insure profitable prodcution of corn and soybean for Louisiana producers. Results from variety tests assist producers in avoiding poor varieties and choosing profitable ones. Unbiased and accurate information on variety performance is highly important for making profitable choices.

Progress 01/01/98 to 12/31/98
Outputs
Commercial variety tests were conducted on corn, cotton, grain sorghum, oats, soybeans and wheat on a Norwood silt loam soil in central Louisiana. The highest yielding varieties over a 3-year period were recommended to producers. An advanced yield test was conducted on 140 experimental strains of soybean. Thirty strains exceeded the yield of most commercial checks and were selected for continued testing and evaluation. Over 280 strains from a discontinued Texas soybean breeding program were grown for evaluation and twelve lines were selected for continued testing and evaluation. Two advanced wheat strains and two advanced oat strains being considered for release were planted for increase of breeders seed. Samples were collected from six replications in the corn hybrid performance trial to test for aflatoxin concentration. Significant differences in aflatoxin concentration between hybrids were noted.
