Özet
This study was carried out to determine the factors affecting the cold tolerance of cotton genotypes and to determine the relationships between cold tolerance and some seed characteristics in 2017. Fourteen cotton varieties belonging to G. hirsutum L. were used as material. Cold (15 degrees C) and normal (30 degrees C) germination condition parameters and fatty acid composition of the cotton varieties were investigated. Resulting, genetic structure and environmental conditions were effective in terms of fatty acid composition and cold tolerance parameters in addition to need of 21 days which is the time to germinate in cold conditions. Varieties Fantom and Stoneville-453 were the highest mid-tolerant, followed by BA-119, Sayar-314 and Deltapine-499, second degree mid-tolerant, and Berke, Deltaopal, SureGrow-125 and Deltapine-332 were medium tolerant in the third grade while Carmen, Gloria, Flora and Teks varieties were sensitive. Positive relationship was observed between cold tolerance and linolenic acid, stearic acid, saturated fatty acids, saturated/unsaturated fatty acid ratio, 100 seed weight, and seed density while negative relationship was between cold tolerance and oleic acid, linoleic acid, palmitic acid, unsaturated fatty acids, unsaturated/saturated fatty acid ratio, oleic/linolenic acid ratio, oleic/palmitic acid ratio, and linoleic/palmitic acid.
