This study was carried out in ??1997-2000 in the east Mediterranean region of Turkey (in Kahramanmaras province) in order to determine earliness, yield and yield components and fiber technological traits of some early maturing mutant cotton varieties from Azerbaijan belonging to Gossypium hirsutum L. (Agdas-3, Agdas-6, Agdas-7, Agdas-17) and Gossypium barbadense L. (Agdas-21) according to randomized block design with four replications. Maras-92 and Sayar-314 (G. hirsutum L.) which are local standard varieties were used as standard varieties. According to four year`s results, Agdas-3, Agdas-7, Agdas-17 and Agdas-21 of the mutant varieties have germinated 2 days earlier than standard varieties. Also, the mutant varieties have opened bolls 3-6 days earlier than standards. Furthermore, Agdas-3, 6, 7 and 17 were the earliest yielding varieties with 83, 82, 83, 84% of first harvest ratio respectively. Also even though Agdas-21 belongs to G. barbadense L. it yielded at the same time with Maras-92 (81%) and earlier than Sayar-314 (78%) and it opened its bolls almost at the same time with standards. Moreover, it was determined that Agdas-7 (3314 kg ha1) and Agdas-17 (3491 kg ha1) were better than standard varieties from the seed cotton yield point, while Agdas-21 showed better characteristics for fiber length (33.31 mm), fineness (4.16 micronaire) and strength (34.42 g tex 1) compared to standard varieties. As a result, Agdas-7 and Agdas-17 due to their earliness and higher seed cotton yield and in spite of its lower yield Agdas-21 due to its earliness and superior fiber quality were found promising for this region., |
