^aVirus-free strains were obtained by single-conidium isolation from the originally virus-infected field isolates.

^bTransformant of strain B2 with an empty vector, pCB1004, carrying a Hyg^r gene.

^cNA, not available.

^dvic genotypes at 6 diallelic loci were determined as described by Short et al. (70), and their nomenclature is according to Choi et al. (71).
