Research Project: Development of Gem Line Starch to Improve Nutritional Value and Bio-Fuel Production

Location: North Central Regional Plant Introduction Station, Ames, Iowa

Project Number: 3625-21000-059-01
Project Type: Specific Cooperative Agreement

Start Date: Jul 29, 2009
End Date: Jul 28, 2014

Characterize the molecular structure of starch granule formation, and develop analytical methods to identify germplasm for high digestibility and resistant starch. Secondly, characterize GEM germplasm for starch nutritional value (for humans and livestock), biofuel potential, and ethanol yield.

Ethanol fermentation tests, and starch digestibility analysis will be conducted on GEM germplasm previously identified with high starch content and/or ethanol content. In addition, other sources of germplasm will be analyzed for resistant starch content. Analytical methods including differential scanning calorimetry (DSC) will be studied to determine applicability for identifying GEM germplasm with desirable starch attributes. The identified germplasm will be recombined for future trials as hybrids, and new breeding crosses made and evaluated.
