Narrative
Maize is an important food crop, especially in many developing countries. In the U.S., maize is the primary energy-supplying grain for animal feed. However, it is often an inadequate source of protein due to deficiencies in essential amino acids such as lysine, methionine, and tryptophan. Methionine is a particularly important amino acid in poultry nutrition; of the maize used for animal feed, 20% is fed to poultry. In the U.S., more than $200 million in synthetic methionine supplements are added to poultry rations annually. USDA may prohibit synthetic methionine-supplemented feed for organic egg production after October, 2008. Thus, the lines hereby available may be even more highly valued. Lines with elevated methionine in A632, B73 and Mo17 backgrounds were developed through a backcrossing program initiated in 1990 at the Minnesota Agricultural Experiment Station in St. Paul, Minnesota. These lines have 11%, 22% and 50% increases in methionine relative to inbreds A632, B73 and Mo17 respectively. Statistical analyses of the NIRS (Near Infrared Reflectance Spectrometry) data using the Tukey and Dunnett tests were performed using the GLM procedures, a function of SAS. Methionine levels in both backgrounds are significant at the 0.05 level compared to their corresponding inbreds. Methionine levels were measured using NIRS and HPLC procedures at the University of Minnesota. A Foss North America (Model 6500) NIRS instrument was used to efficiently screen genotypes. A NIRS equation was developed for predicting methionine levels of ground-kernels. On an individual sample basis, the correlation between NIRS-predicted methionine level and HPLC-measured methionine was 0.79. The correlation between genotype means of NIRS-predicted methionine and genotype means of HPLC-measured methonine was 0.91. Elevated whole-kernel methionine levels improve the protein and nutritional quality of the maize grain.

Pedigree
Description:
Maize lines elevated in methionine were generated by crossing inbred lines A632, B73 and Mo17 to a high-methionine donor parent, BSSS53. A632, B73 and Mo17, yellow endosperm corn-belt dent lines, were the recurrent parents in the backcross scheme. The converted A632, B73 and Mo17 lines (3-5 backcrosses) have 11%, 22% and 50% elevated methionine levels, respectively. BSSS53 is a random line isolate from the Iowa Stiff Stalk Synthetic population.
