Özet:

The study was carried out to determine effect of environment on fiber quality in cotton grown in the Efeler and Söke areas of Aydın province, Bergama, Menemen, Torbalı areas of İzmir province, Sarayköy area of Denizli province, Milas area of Muğla province, Akhisar area of Manisa province,in the Aegean Region of Turkey in 2020.In this study Gloria variety was used as research material.The experiment was arranged as randomized complete plots design. The effect of locations on nep count, nep size, ginning percentage, fiber strength, fiber fineness, fiber length, uniformity index of fiber length, maturity degree of fiber, fiber elongation, short fiber content, yellowness rate of fiber, fiber brightness, trash count in fiber, were found to be significant. The effect of locations on 100 seed weight were found to be insignificant. In the study, it was determined that 100 seed weight was not affected by environmental conditions, while other characteristics were affected by environmental conditions. It was determined that the cotton grown in Söke area was most highest in terms of ginning percentage, maturity degree of fiber, yellowness rate of fiber, trash count in fiber, nep count and nep size. Menemen area gave the highest value in terms of fiber length, uniformity index of fiber length, fiber fineness and fiber elongation. The treatments of uniformity index of fiber length, short fiber content and trash count of cotton fiber were highest obtained in Bergama and Efeler areas. Torbalı and Efeler areas gave as highest as maturity degree of fiber the cotton grown in Söke area. Milas area showed similarly the highest value in terms of fiber fineness as compared Menemen. The cotton in Bergama area belongs to the highest value in terms of fiber strength and fiber brightness..
