Continued Screening of Exotic Maize Germplasm for High Starch-Amylose

High-amylose corn starch is used for a number of food and nonfood uses such as the production of adhesives, gum candies and biodegradable plastics. In a previous study, Amylomaize class VII starch (70% amylose content) was identified from experimental lines possessing the recessive amylose-extender (ae) allele together with modifying genes from two Southwestern corn populations Cochiti Pueblo and Zia Pueblo (PI 218139). For this study, one-hundred populations originating from Japan, Turkey, Chile, Canada and the US were also screened for high-amylose. In this study a different Zia Pueblo accession (PI 218188) showed an average amylose content of around 70%. In addition a line derived from Zia Pueblo (B100 x ((NRC5357 Zia Pueblo x (OH43ae x H99ae)) also showed an amylose content of 77.6%. These results suggest that a modifying gene leading to high-amylose levels is shared among several Pueblo corns from the Southwestern US.
