Genetic Variation Among High Amylose Genotypes for Starch Thermal Properties Measured by Differential Scanning Calorimetery
Kimberly Kruse
Dr. Mark Campbell, Faculty Mentor

A plant breeding program at Truman State University has focused on development of high amylose corn over the past ten years. Selection for high amylose genes to differentiate genotypes having 70% starch amylose versus 50% starch amylose has routinely been done using a standard colorimetric wet chemistry analysis. A previous study revealed that thermal properties measured by differential scanning calorimetry varied among high amylose genotypes in this high amylose range. Specifically, genotypes having high amylose modifier genes fixed to homozygosity had a gelatinization peak temperature ten degrees higher than heterozygous genotypes. This study will report on thermal properties based on mixing starch of various genotypes and inheritance of thermal properties from evaluation of parents and their offspring.
