Abstract

Genetic diversity was evaluated among 7 diploid (G. arboreum) and 15 tetraploid (G. hirsutum) cotton cultivars using Random Amplified Polymorphic DNA (RAPD) and morphological markers. RAPD markers were efficient and detected 88% polymorphism. The diploid and tetraploid cultivars could be divided into separate clusters at 30% similarity with RAPD and 20% similarity with morphometric markers. Classification of the cultivars based on the two markers showed a high degree of agreement with a correlation of (+) 0.90.Both markers revealed higher diversity among diploids than among tetraploids.
