Determination of Combining Ability in Sunflower Parents According to Line X Tester Analysis Method

Abstract

In Turkey, hybrid seeds are used in sunflower oil production, and hybrid varieties are preferred by producers due their features such as high yield performance, superior quality characteristics, uniform appearance, resistance to certain diseases and orobanche (Kaya et al., 2009). Therefore, breeding programs in sunflower in the world are generally directed towards hybrid breeding (Khan et al. 2004;Dagustu et al. 2012). In these breeding programs, the target is to obtain, to develop inbred lines with properties such as high seed yield and oil content, hence high oil yield, earliness, resistance to diseases and pests and so on, and to obtain hybrids with desired performance through them taking advantage of hybrid overgrowth (Vear, 2016). However, it is also very important that these bred lines maintain their superior performance under different environmental conditions. Therefore, knowing the factors affecting the oil yield, yield elements that play a decisive role and the relationships between, in the sunflower, which is an oil
