Abstract: Cotton is the most important source of natural fiber used in the textile industry and oil. Cotton provides raw materials for approximately 50 industry branches; it is a source of livelihood for about 200 million people worldwide. There are about 20 biotic and abiotic stress factors that limit the production of cotton. Drought is one of the most destructive abiotic stresses in all cotton-growing areas. Since drought is an abiotic stress factor that directly or indirectly affects the entire world negatively, a multifaceted approach is necessary to combat drought. This experiment was conducted in the University of Bingol, Genç Vocational School, Agriculture Biotechnology laboratory, in May 2023 year. The objective of the research was to explore upland cotton cultivar’s reaction to drought conditions induced by osmotic pressure stresses of 0 MPa (control), -4 MPa, -6 MPa, -8 MPa, and -10 MPa using PEG6000 chemical on Ten upland cotton cultivars. Germination percentage (GP, %) of cultivars was measured. In conclusion, In summary, May 344 and May 455 cultivars display notably superior tolerance to Osmotic Stress in contrast to other varieties, with Beren and SG-125 also showing relatively favorable tolerance levels. These discoveries offer valuable perspectives into the germination characteristics of these cultivars across diverse osmotic environments. Cultivars exhibiting consistently high germination percentages (GP) should be sown in uncontrolled field conditions to evaluate their germination and emergence potential. Moreover, cultivars demonstrating a fast germination rate and emergence may have genes associated with the earliness traits in cotton.
