A study of the genetics of resistance to scald in barley was carried out in the field and in the greenhouse at Davis, California.

La Mesita differed from susceptible Atlas by a single dominant gene for resistance to scald.

Trebi and California No. 1311 have both a dominant and a recessive gene for resistance.

The genetic analysis of Turk was incomplete. Six lines were extracted from Turk × Atlas, which had the same high resistance as Turk. They all gave monohybrid ratios when crossed again with Atlas. These were used in the breeding of scald-resistant Atlas 46.

The single gene extracted from Turk appeared to be identical with the dominant gene found in La Mesita, Trebi, and California No. 1311.
