Alpha X O.A.C. 21 Dorsett x O.A.C. 21 C.I. 1370 X O.A.C. 21 O.A.C. 21 x Mars O.A.C. 21 x Mars I T IS a well established fact that diastatic power is a major criterion of malting quality in barley. Diastatic power has been shown to be (2, 4, 7 ) a strain or varietal characteristic, and therefore, barley breeders can select strains which have a consistent relative activity for this enzyme. One of the major obstacles in selecting barley strains with a desired diastatic power is the lack of an easy method for evaluating this characteristic in the early generations of a barley cross. Even the ferricyanide method for determining diastatic activity in barley grain, developed by Anderson and Sallans ( I ) , it too laborious to be used on the large number of segregates that need to be analyzed in a barley improvement program. Selection for good agronomic barley strains with desirable diastatic activity would be greatly facilitated if an association could be established between certain morphological characters and high or low diastatic power.
