“+” denotes extra resistance that could not be attributed to postulated genes in the lines for at least one of seven races; “#”denotes putative nonfunctional alleles where phenotypes did not confirm gene postulations based on diagnostic markers; and “$” denotes that the functional allele appeared to be heterogeneous.
“S” denotes susceptible infection type (IT) 3 or 4; “/” denotes heterogeneous, the predominant type given first; “LIF” denotes low infection frequency with fewer pustules.
