The amount of genetic variation was evaluated by polymerase chain reaction amplification with a set of twenty one random 10-mer primers. All amplifications revealed scorable polymorphisms among the isolates, and a total of 23 band positions were scored for the 21 primers tested. Genetic distances among the isolates were calculated, and cluster analysis was used to generate a dendogram which showed relationships between them. These results suggest that the geographic groups were strong. KW - Persea americana KW - Root rot on Avocado KW - RAPDs DO - 10.32604/phyton.2009.78.025
