Stability and adaptation of some cotton (G. hirsutum L.) genotypes to Çukurova region conditions

Eight cotton cultivars grown in four different locations )Ceyhan, Antakya, Karataş and Yüreğir) in Çukurova region conditions were examined to determine the adaptation ability.for the yield (kg/da), yield components and fiber quality characteristics. It has been observed that the characteristics of varieties were significantly affected by locations. Cotton varieties used in this study showed different adaptation abilities in different environments.According to results of adaptabilities for seed cotton yield, MAY 22 cultivar showed well adaptation to all environments, DP 419, ST 468, MAY 18 cultivars showed specific adaptability to favorable environments, ST 373 cultivar showed weak adaptation to all environments, Ç.1518 cultivar showed specific adaptability to unfavorable environments.
