Title Of Article :
The effect of different nitrojen doses on some quality parameters in durum wheat F2 hybrid combinations
Abstract :
This study was conducted at Diyarbakır conditions in 2010-2011 wheat growing season, three commercial (Zenit, Spagetti and Lavente), and three landrace cultivars (Mısırı, Mersiniye and Menceki), and durum wheat parents and their 15 different hybrid combinations at F2-stages was grown as materials under low (N0, no N fertilizer), moderate (N1, 120 kg N ha−1) and high (N2, 240 kg N ha−1) N conditions were investigated in three different nitrogen doses. In this study, examining of the quality traits (protein content, gluten content, zeleny sedimentation and grain hardness) of breeding materials and determination of availability as breeding material were investigated. While the increase of nitrogen doses protein and gluten content have a positive effect, zeleny sedimentation and grain hardness have just effected up to moderate nitrogen level. The cultivar Spagetti showed positive and high general combining ability (GCA) effects for zeleny sedimentation and grain hardness at moderate N level. Also it was the best combiner for zeleny sedimentation and grain hardness at moderate N level The Menceki was best combiner for GCA effects for protein content and gluten content at moderate N level. Hybrids 1x4 and 4x6 showed positive specific combining ability (SCA) effects for protein content, zeleny sedimentation and grain hardness at moderate N level. these varieties had best SCA effects for protein content, zeleny sedimentation and grain hardness atmoderate N level.
