A type of barley has been discovered in which the amylose content of the starch is approximately double that of all normal varieties of barley. This high amylose strain (Glacier, Scottish Plant Breeding Station number AC 38) appears to be a home-grown variant of the Canadian 6-row barley Glacier and the amylose content of the parent variety obtained from Canada is no higher than that of normal barley.
