A New Strain of Barley With Starch of High Amylose Content

Abstract

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.

Peroxidase Isozymes in Mature Barley Kernels

“…1, 2) and with OD ( Fig. 1) (Merritt 1967) and an experimental barley selection, , is demonstrated in Fig. 2.…”

The cluster structure of barley amylopectins of different genetic backgrounds

“…Another example is high-amylose barley, which generally contains 40-70% of amylose in the starch. The mutant Glacier Ac38 was the first reported and was shown to contain 44-47% amylose [7]. Later it was shown that the controlling gene was amo1, which is located on chromosome 5 (1H) [8].…”

Modulation of resistant starch and nutrient composition of barley grain using organic acids and thermal cycling treatments

“…Amylose has the property to form a thermally stable RS3 complex, resistant to amylases . It is known from literature that native barley grain starch, as used in our study, consists of around 25% amylose and 75% amylopectin . Usually, high amylose barley varieties, containing up to 45% amylose , are used in studies like this to yield high amounts of RS .…”
