Genetic Variation in Fusarium moniliforme Isolated from Seeds of Different Host Species from Burkina Faso Based on Random Amplified Polymorphic DNA Analysis

Random amplified polymorphic DNA (RAPD) analysis was used to assess genetic variation among 28 isolates of Fusarium moniliforme isolated from seed samples of six host species (rice, sorghum, maize, cotton, hibiscus and parkia) collected in Burkina Faso. Score-able markers (128) were obtained with 20 random decamer primers. Cluster analysis with UPGMA using genetic distances showed that the isolates were of five main groups. In general, isolates from the same host species were found to group together in the same cluster. The isolates from cotton and hibiscus were more closely related to each other than to the isolates from sorghum, rice and maize. Results indicate that host preference is possibly a factor in the differentiation of isolates
