Genetic diversity in Gibberella fujikuroi(Fusarium section Liseola)from rice

摘要

Bakanae disease,caused by several species ofFusarium section Liseola is an important dis-ease of rice(Oryza sativa L.).It is unclearwhether the isolates with different morpholog-ical features in anamorphs were genetic differ-ent.Gibberella fujikuroi is the teleomorph ofspecies of Fusarium section Liseola,and en-compasses at least seven mating populations(MPs).Vegetative compatibility group(VCG)has been used to study the relation- ships between the strains within a fungalspecies.We studied the genetic diversity ofpathogenes of rice bakanae disease by usingthe MP and VCG techniques.
