Line x Tester (Çoklu Dizi) Yöntemi ile Geliştirilen Bazı Pamuk (Gossypium hirsutum L.) Genotiplerinin Elbistan Koşullarına Uyum Yetenekleri-II; Lif Özellikleri

Abstract

The aim of cotton cultivation is fiber production with high yield and quality. In this study, parental and hybrids adaptability (GCA and SCA) and gene effects were examined in terms of fiber yield and fiber quality characteristics. The study was carried out in Elbistan plain in 2012 year after the fallowing of hybridization which made in Kahramanmaraş conditions in 2011 year. Elbistan is located at high elevation (about 1100 m-1500 m) from sea level in Turkey and junction of Mediterranean, Central and Eastern Anatolia Regions, which has short period for cotton cultivation . Eight cotton ( Gossypium hirsutum L.) varieties and fifteen F 1 hybrid were used as plant material that obtained by Line x Tester mating design were planted in a randomized block design with four replications. As a result of study, while the maximum fiber yields were determined as 113.3 kgda -1 (1x4, Stoneville 468 x Beli İzvor 432) and 102.83 kgda -1 (Fantom) in Elbistan conditions, and non-additive genes was estimated fiber yield and other fiber properties. The testers supported the fiber fineness , strength and refrectance of fiber while the lines have supported fiber yield and yellowness variations. Furthermore, lines x tester interaction have been supported fiber length, uniformity, elangation and short fiber contents variations. The highest broad-sense heritability determined for fiber yield (H=0.91) and fiber fineness (H=75). Moreover, in this study, while the 1x4 (Stoneville 468 x Beli İzvor 432), 1x5 (Stoneville 468 x Primera) and 3x4 (Furkan x Beli İzvor 432) hybrids showed significant SCA values for fiber yield, micronaire and yellowness, respectively, Stoneville 468 (fiber yield, micronaire and yellowness) Beli İzvor 432 (fiber yield), Berke (fiber strenght), Fantom (fiber fineness) cultivars have showed significant GCA values.
