Hierarchical clustering was carried out using UPGMA (Unweighted Paired Group Method using Arithmetic Averages) for fiber length, fiber fineness and fiber strength and 10 groups were defined. Cluster B and cluster I contain 5 and 3 genotypes with having considerable values for fiber length and fiber fineness. The cluster B contains Askabat 100, Sealand 542, Giza 45, Delcerro and Ege 69 which had long stable and finest fiber characteristics. Cluster I were Giza 75, Giza 70 and ED 110. Also, it could be defined that Cluster B and I were late maturity and low lint percentage. The choosing of parents from these clusters may be a problem in terms of earliness and lint percentage for long stable cotton breeding.]]>Barut, A., O. Cargan, Z. Yuksekkaya and H.B.
