If genotype (G) ranks change from one environment (E) to another, genotype by environment interactions (GEI) reflects the need for testing Gs in numerous Es in order to obtain reliable results. The aim of this study was to compare 16 non-parametric stability statistics (NPSSs) for GEI on grain yields of 15 durum wheat genotypes, consisting of 11 advanced lines selected from Turkish National Durum Wheat Breeding Program (TNDWBP) and four checks, tested in 12 rain-fed environments during the 2 cropping seasons (2009-2010 and 2010-2011) in Turkey. The combined ANOVA indicated that G, E and GEI effects were significant for grain yield. According to analyses of NPSSs, the highest in ranking (TOP), percentage of adaptability (PA), rank mean (RM) and yield-stability (YS) statistics were positively associated with grain yield and therefore characterized under the dynamic concept of stability. In addition, spearman rank correlation analysis revealed that only TOP, PA, RM and YS statistics would be useful for simultaneous selection for high grain yield and stability. Based on the 16 NPSSs used in this study, Dumlupinar cultivar (G15) was both the most stable and one of the highest yielding ones. On the other hand, G5 and G7 were the most stable ones among the advanced lines tested, but their yield performances were lower. As a result, this study showed that the crossing block of TNDWBP should be enriched by germplasm being capable of dynamic stability, wide adaptation and higher yielding.

This study was conducted to determine grain yield and some quality traits of 20 durum wheat genotypes under rainfed conditions in 2012-2013 growing season at Konya-Center and İçeri Çumra. In previous years, improved in durum wheat breeding program 16 lines and commonly grown in the Central Anatolian Region 4 cultivars (Kızıltan-91, Ç-1252, Eminbey ve Kunduru1149) were used as plant material. The research was arranged in a randomized block design with four replicates. Grain yield, plant height, thousand kernel weight, test weight, protein content, SDS sedimentation value and color value were evaluated in this research. According to the results including two environment averages; grain yield, plant height, thousand kernel weight, test weight, protein content, SDS sedimentation value and color value of genotypes, were between 2027.0-3679.2 kg ha -1 , 70.9-112.2 cm, 34.7-44.4 g, 73.7-77.0 kg, 11.0-14.2 %, 10.3-26.8 ml and 19.5-24.2, respectively. On average of two environments, in terms of grain yield, 1, 3, 4, 6, 7, 8, 18 and 19 numbered lines had above the overall grain yield (3040.6 kg ha -1

In this study some quality characteristics and mixograph parameters of some durum wheat (Triticum durum L.) varieties and advanced lines were investigated and the relationship between them was determined. The material used in the study was grown in rainfed and irrigated conditions in 2016-2017 growing period at Bahri Dağdaş International Agricultural Research Institute. Some physical, chemical and rheological properties of durum wheat samples as well as some mixograph parameters (peak time (PT), peak height (PV), right peak slope (RPS), final peak width (CT), peak area (TINT) area (TTINT) and mixograph scale (MS) were examined. When durum wheat samples were evaluated in terms of MS which is an important indicator of gluten strength, Eminbey (7.5), Meram (6.0) and Selçuklu (5.25) varieties were found above the average (4.38). Positive correlation was obtained between PT and SDS (0.862), DDT (r=+0.791), STB (r=+0.862); and negative correlation was obtained between DS12 (r=-0,848). Positive correlation was obtained between PV and SDS (r=+0.654), DDT (r=+0.425) and STB (r=+0.483). Positive correlation was obtained between CT and SDS (r=+0.820), DDT (r=+0.681) and STB (r=+0.824) TINT and SDS (r=+0.855), DDT (r=+ 0.726) and STB (r=+0.853) and significant at p<0.01, statistically. In this study, with the use of a mixer, a small amount of sample was obtained in a short time about the quality of durum wheat. However, this subject will contribute to the use of mixograph device in durum wheat with further studies.

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.
