摘要: Knowledge about the genetic diversity within a germplasm allows for more effective and efficient use of resources crop improvement programs. Diversity assessment 48 tropical drought-tolerant maize inbreds, 24 each from CIMMYT IITA, was carried out with microsatellite markers to determine divergence between two groups inbred lines. Eighty-one polymorphic SSR were used assessment. Results showed that average number alleles per locus 3.7. The mean information content (PIC) 0.51 whereas modified Roger’s distance (MRD) 0.49. estimates IITA lines higher than among or linkage cluster analysis separated into broad along institutional observed sub-groups main group reflections relationships based on pedigree records. F ST value 19.5% reflects high level differentiation results highlighted presence appreciable can be exploited superior hybrid development.
