Genetic variability of Colletotrichum sublineolum through ISSR markers

The occurrence of diseases is a limiting factor in the development sorghum crop. Among that causes losses production, anthracnose main and most severe, mainly by genetic variability pathogen. In this context, aim study was to evaluate Colletotrichum sublineolum isolates. DNA were extracted from 56 monosporic isolates C. using extraction kit, perform analysis diversity used ISSR primers. After amplification, it determined polymorphic information content (PIC), allelic frequency, UPGMA Tocher clustering analyzes and, software Structure, structure. According descriptive Sublineolum isolates, primer AP1 presented higher value (PIC). frequency observed loci 06, 09, 10, 24, lowest locus 02. As for method, tendency grouping according geographic origin addition demonstrating between introgression among
