Abstract
Thirty-two resistant varieties of winter type barley from the

United States Department of Agriculture's World Collection were chosen

for a study of the inheritance of scald resistance.

They were crossed with Wong (0.1. 6728), a highly susceptible

variety and with Hudson (0.I. 8067), a highly resistant variety. The

crosses with Wong were made for the purpose of determining the number

of pairs of genes for resistance in each of the resistant varieties.

The crosses with Hudson were made for the purpose of determining whether

any of the resistant varieties has genes for scald resistance at loci

other than in Hudson. The F2 seedling populations from these crosses

were studied in the greenhouse at Blacksburg in the early spring of

1960 and the winter of 1961.
