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.
