a
Fertility of the crosses was assigned based on the number of cleistothecia per junction zone. HF, >100 cleistothecia with ascospores; MF, <100 cleistothecia with ascospores; LF, 0 to 20 cleistothecia without ascospores.
b
Molecular strain typing was done by PCR fingerprinting using microsatellite-specific primer M13. Two groups, T1 and T2, were identified.
