Cotton is an important crop in terms of economic and strategic impacts. Drought stress is one of the most
important environmental stress factors which negatively affects growth and yield of plants in Turkey as occurred in many
countries in the world. In this study, 11 different cotton cultivars selected based on their agronomical characters were tested
under water deficit irrigation strategies. Thus, it was aimed to select and/or determine appropriate new varieties for breeding
new national materials resistant to drought stress, and to characterize with the molecular microsatellite markers. According
to the different irrigation levels (25%, 50%, 75% and 100%) plants were observed under the stressed conditions at the
irrigation levels of 50% and 25%. Among the tested varieties, Tamcot Sphinx, Tamcot 94, Tamcot CamdEs and BA525
varieties were found to be more water stress tolerant than others in terms of germination time and germinated plant. The
UPGMA (Unweighted Pair-Group Method Using Arithmetic Averages) analysis was carried out using 28 markers with
average 0.306 polymorphism information content (PIC) for molecular characterization studies. Based on the UPGMA
results, the varieties were clustered into two groups. It is expected that the results obtained from this study might provide
considerable data for improving new drought tolerant varieties.
