Date of Defense 1961-05-26 Availability restricted AbstractThirty-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.
