Inheritance of resistance to Rhynchosporium secalis (Oud.) J.J. Davis in Barley
MetadataShow full item record
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.
