Knowledge of genetic distances among individuals or populations in plant breeding programmes can be used to complement phenotypic information in choosing individuals to use in breeding for populations with high genetic variability. Random Amplified Polymorphic DNA (RAPD) techniques may be advantageous in studies of genetic relationships. This paper discusses research to identify primers that produce polymorphism among cotton (G. hirsutum L.) genotypes, to compare the effects of primer length in the generation of polymorphism, to estimate genetic distances among 23 genotypes from eight countries using RAPD analysis and tro compare such estimates with those obtained through phenotypic analysis.
