Variabilidade genética de Colletotrichum guaranicola usando marcadores AFLP

Abstract

The genetic variability of twenty Colletotrichum guaranicola (Albuq.) isolates from different fields of guarana in Amazonas, was studied using molecular AFLP markers. The isolates were separated into two groups. The genetic variability coefficient was 0.0216 and the genetic similarity was 94.5%, confirming that the isolates belongs to the same species, however, an intraspecific variability was observed.
