Agronomic, fiber and seed quality traits of naturally coloured cottons in east Mediterranean region of Turkey

摘要

This study was carried out during 2002-2005 in the east Mediterranean region of Turkey (in Kahramanmaras province), at the experimental field of Agricultural Faculty of Kahramanmaras Sutcu Imam University. Four naturally coloured cotton lines (light brown, dark brown, cream and green) (G. hirsutum L.) brought from Azerbaijan National Academy, Genetic Resources Institute and white linted cotton varieties of Maras-92 and Sayar-314 (G. hirsutum L.) which are of standard varieties of the region were used as test material. Four year's field trials were established according to randomized block design with four replication. According to four year's results, investigated coloured cotton lines have given lower yield and ginning outturn than standard varieties. However cream and light brown lines were similar to standards for plant height, sympodia, boll number per plant, seed cotton weight per boll, fiber quality characteristics, kernel oil and protein content. From results it may be concluded that cream and light brown lines are remarkable lines a those may be used for further breeding programs for improvement of desired trais.
