2011 Annual Report
1a.Objectives (from AD-416)
Develop cutting-edge analytical standards to provide a platform for essential activities to support soybean composition improvement in the U.S., including amino acids, fatty acids, protein, oil, and other important constituents.
1b.Approach (from AD-416)
Using new wet chemical methods, improved near infrared calibrations will be performed and compared to calibrations by other NIR users. A wider range of soybean composition will be worked into the calibration. Soxhlet and nitrogen analyses from newly obtained equipment will be used in the calibration. Carbohydrate analyses will be performed on a large number of soybean samples and added to the current calibration.
Continual calibration of near infrared (NIR) methods and the use of routine standards has improved the quality of analysis generated for thousands of soybean samples provided by breeders. Congressionally mandated Specific Cooperative Agreements (SCA) with the University of Illinois and Purdue University for improving soybean and wheat genetics were renewed in July of 2010 and continued through 2011. These SCA projects are developing improved disease resistance in wheat and soybean. Near infrared calibrations were developed for the determination of phytochemicals in ground mint plant material and this calibration has been used to support work in research project 3620-41000-150-00D. In 2011, work related to developing a non-destructive rapid single seed method for the determination of seed viability in collaboration with the North Central Regional Plant Introduction Station in Ames, IA continues.
Provided analytical support for breeders throughout the U.S. Soybean breeders are dependent on rapid, standardized, and accurate chemical properties to guide their breeding efforts. In 2011, we saw a continual increase in utilization of this analysis program with oil, protein, and moisture content determinations rising to 39,567 soybean samples by near infrared, as well as fatty acid profiles of 14,912 samples. Agricultural Research Service scientists in the Functional Foods Research Unit at the National Center for Agricultural Utilization Research in Peoria, IL, analyzed these data which was compiled and published in the annual USDA publication, 2011 Coordinated Soybean Analysis. All of these data have been provided to breeders throughout the U.S. where this information is critical to the development of improved soybean varieties.
