Abstract
The proportion of beta-amylase activity that is free, or water-soluble, is useful in screening barley hybrid lines for potential malting quality. It was found to be at one of two distinct levels in 56 barley varieties. The levels, designated high and low, are independent of year and location. Tests were made on F2 and backcross populations derived from varieties differing in level of free beta-amylase. The results indicated that the level is dependent on the action of a single gene-pair with incomplete dominance. The level of free enzyme activity is apparently inherited independently of total beta-amylase activity.
