SRAP and ISSR molecular markers-trait associations in sorghum genotypes

In order to better understand the relationship genotype-phenotype, marker-trait associations in 7 sorghum genotypes were studied using a set of 75 DNA-based molecular markers (39 SRAP and 36 ISSR polymorphic markers). SRAP and ISSR analysis showed similar average of the percentage of polymorphism (%P) which was 51.37 and 53.03%, respectively, as well as the average of polymorphic information content (PIC) which was 0.17 and 0.16, respectively. Moreover, the means of marker index (MI) were 0.68 and 0.73 for SRAP and ISSR markers, respectively
