Grain yield of 15 durum wheat (Triticum durum Desf.) genotypes consisting of 13 cultivars and 2 advanced lines, tested in a randomized complete block design with four replications across 8 environments of Central Anatolian Region of Turkey was analyzed using nine parametric stability measures. The objectives were to assess genotype--environment interactions (GEI), determine stable genotypes, and compare mean grain yield with the parametric stability parameters. To quantify yield stability, nine stability statistics were calculated (, α i and λ i ). Yilmaz-98, Cakmak-79, Kiziltan-91, Selcuklu-97 and C-1252 were more stable cultivars, which had 9, 8, 6, 6, 6 out of all 9 stability statistics used, respectively. Especially, among these cultivars, Yilmaz-98 and Cakmak-79 were the most stable cultivars. Furthermore, three-dimensional plots of mean response versus each stability statistic were shown to visually evaluate the yield potential and stability estimates of the genotypes. Genotype mean yield ( -x) was significantly positively correlated to the regression coefficient (b i ), environmental variance and genotype to the environmental effects (α i ), indicating that high grain yielding genotypes had larger values b i , S 2 i , andCV i , α i and b i , were significantly correlated, indicating that they measured similar aspects of stability.

This study was conducted to determine the farinograph parameters and some quality characteristics of 15 bread wheat varieties grown in rainfed conditions in 2011-2012, 2012-2013 and 2013-2014 according to a randomized block trial design with two replication. The farinograph parameters (development time, water absorption, stabilsity and softening at the 12th minute), protein ratio, grain hardness, Zeleny sedimentation and bread volume of bread wheat varieties were investigated. Three-year average value ranges of quality traits; protein ratio 13.51-16.02%, grain hardness PSI 45.74-71.05, Zeleny sedimentation 34.67-63.67 ml, bread volume 340-519.17 cm3, farinograph development time 3.75-12.30 min., farinograph water absorption 57.43-65.72%, farinograph stability 4.62-16.92 min. and the farinograph 12 min. softening value 38.66-132.33% was determined as. Significant quality differences were determined between varieties and years, and the highest values in terms of quality traits were obtained in 2013-2014. High values were obtained in Konya-2002, Tosunbey, Karahan-99 and Eraybey varieties in terms of farinograph development time, water absorption and stability values.

ÖzBu araştırma, 2013-2014 yetiştirme döneminde ileri kademe bazı ekmeklik buğday genotiplerinin tane verimi ve bazı kalite parametrelerinin belirlenmesi amacıyla yürütülmüştür. Araştırma materyali; Bahri Dağdaş Uluslararası Tarımsal Araştırma Enstitüsünce yürütülen ıslah çalışmaları kapsamında bölge verim kademesinde yer alan 14 hat ve 6 standart çeşitten oluşmaktadır. Çalışma 9 çevrede (Konya, İçeriçumra, Gözlü, Koçaş, Karaman, İkizce, Malya, Eskişehir, Hamidiye) Tesadüf Blokları Deneme Deseninde 4 tekerrürlü olarak yürütülmüş, kalite parametreleri Konya ve İçeriçumra çevrelerinde 2 tekerrürlü olarak elde edilmiştir. Çalışmada tane verimi (kg/da), bintane ağırlığı (g), protein (%) ve Zeleny sedimentasyon (ml) özellikleri incelenmiştir. Çevre ortalamaları değerlendirildiğinde tane verimi bakımından en yüksek değer 383 kg/da ile Malya'dan, en düşük değer 114 kg/da ile Hamidiye'den elde edilmiştir. Çalışmadaki tüm genotipler 9 çevrede tane verimi bakımından değerlendirildiğinde en yüksek değer 269 kg/da ile hat15'den elde edilirken en düşük değer 171 kg/da ile hat17'den elde edilmiştir. Denemede ele alınan kalite parametrelerinden bin dane ağırlığı 27. Assessment of Advanced Bread Wheat Genotypes (Triticum aestivum L.) for Yield and Some Quality Traits under Rainfed Conditions AbstractResearch materials are consist of the scope of breeding studies by Bahri Dağdaş International Agricultural Research Institute's 14 lines and 6 varieties from Regional yield trial. Study carried out at 9 environment (Konya, İçericumra, Gözlü, Koçaş, Karaman, İkizce, Malya, Eskişehir & Hamidiye) with randomized block pattern in 4 replications, quality parameters recieved from Konya & İçeriçumra environment with 2 replication. The study grain yield (kg/ha), thousand kernel weight (g), protein (%) and Zeleny sedimentation (mL) properties were investigated. The highest average grain yield in terms of environmental value as assessed 383 kg / ha with the Malya; were the lowest, 114 kg / ha were obtained by the Hamidiye. With regard to grain yield in all 9 genotypes at the study highest value around 269 kg / ha from the line 15 while the lowest value 171 kg / ha were obtained from the 17 line. The quality parameters of the experiment discussed in thousand grain weight between 27.4-38.2 g, 12.26-14.80% protein content ranged between and Zeleny sedimentation between 34.7-57.2 mL. When the control varieties and the other lines one line showed superior characteristics and we applied this line as a candidate to Variety Registration and Seed Certification Center and was transferred to registration trials.
