Phytoglycogen and starch components were assayed in twelve lines of fresh kernels belonging to different types of corns such as normal corn (field corn), sweet corn and quality protein maize (QPM). The technique, using single kernel and a series of digestions and dilutions, measured glucano lactone contents of soluble and insoluble components in the three groups of corn with distinct and diverse uses. Extensive variability was found among sweet corn, field corn and QPM for the water soluble and insoluble carbohydrate components and kernel weight, especially for genotypes belonging to different types of corn. Further, such differences are broadly related and comprehendible to distinct types which give an insight into the unique characteristics and their end use.

Abstract


Phytoglycogen and starch components were assayed in twelve lines of fresh kernels belonging to different types of corns such as normal corn (field corn), sweet corn and quality protein maize (QPM). The technique, using single kernel and a series of digestions and dilutions, measured glucano lactone contents of soluble and insoluble components in the three groups of corn with distinct and diverse uses. Extensive variability was found among sweet corn, field corn and QPM for the water soluble and insoluble carbohydrate components and kernel weight, especially for genotypes belonging to different types of corn. Further, such differences are broadly related and comprehendible to distinct types which give an insight into the unique characteristics and their end use.
