Abstract
HABGOOD1 proposed a system for naming physiologic races of plant pathogens making use of the characteristics of binary notation, in which the reaction of each host to a given isolate is written down using 0 for resistance and 1 for susceptibility, the differential hosts being arranged in a fixed linear order. The resulting pattern of 0s and 1s is then considered as a binary number and converted to decimal notation. This system has been adopted for physiologic races of Puccinia striiformis infecting wheat2.
