*    isolates designated according to reaction in original differential test and the

     cultivars from which they were collected:

Apex +            isolates which gave increased numbers of colonies on Apex and Riviera

Apex 0            isolates which gave no infection on Apex and Riviera

mlo isolates   collected from plots of mlo cultivars
