MustafayevSefer 1220091220In the study carried out in 2002-2003 in the East Mediterranean region of Turkey (in Kahramanmaras Province), four different naturally coloured cotton (Gossypium hirsutum L.) (dark brown, light brown, cream and green) lines from Azerbaijan and two white linted cotton varieties (Maras-92 and Sayar-314 (G. hirsutum L.)) of the region were used as material. The aim of this study was to determine seed cotton yield and yield components and major lint quality traits of investigated coloured cotton lines comprising white linted local standard cotton varieties. Field trials were established in randomized block design with four blocks. According to two years results, it was determined that naturally coloured cottons were found similar to both white linted standard cotton varieties for sympodia number and seed cotton yield. For boll number per plant, except green cotton line all coloured cotton lines were similar to standard varieties or even some of them were better than standards. For ginning outturn, dark brown, cream and green cotton lines were found statistically similar to standard Maras-92. But all naturally coloured cotton lines had lower seed cotton weight per boll and generally lower fiber quality than white linted standard varieties. For fiber length and fiber strength cream cotton line was the best coloured cotton. And for fiber fineness only green cotton line was better than both standards. It can be said that naturally coloured cotton lines need to be improved especially for fiber quality characters in the East Mediterranean region of Turkey.]]>Asai, R.G. and S.
