| genetic variability of cercospora coffeicola from organic and conventional coffee plantings, characterized by vegetative compatibility. | cercospora leaf spot is a destructive fungal disease that has become a threat to the coffee industry in brazil. nevertheless, little is known about populations of its causal agent, cercospora coffeicola. we evaluated the potential of using nitrogen-nonutilizing (nit) mutants and vegetative compatibility groups (vcgs) to characterize the genetic variability of the c. coffeicola population associated with coffee plantings in minas gerais state (mg), brazil. a total of 90 monosporic isolates were o ... | 2008 | 18943409 |
