Twenty five isolates of Trichoderma harzianum and Trichoderma viride were obtained from rhizosphere soil of turmeric and ginger collected from Belagavi and Bagalkot districts of Karnataka and eight potential isolates based on antagonistic activity were studied using RAPD PCR. The genetic relatedness among two isolates of Trichoderma harzianum and six isolates of Trichoderma viride were analysed with five random primers. RAPD profiles showed genetic diversity among the isolates with the formation of two major clusters. Analysis of dendrogram revealed that similarity coefficient ranged from 0.15 to 0.95. Molecular variability among the potential isolates showed 81 amplified bands out of which 77 were polymorphic and 4 were monomorphic.
