Abstract:

Identification of adapted genotypes with high grain yield is the most important goal in durum wheat breeding programs. To study adaptation and grain yield stability of durum wheat genotypes, 18 durum wheat promising lines with two commercial durum and bread wheat cultivars were used. The durum wheat genotypes were evaluated in four locations; Isfahan, Karaj, Kermanshah and Neishabour in temperate agro-climate zone of Iran in 2013-14 and 2014-15 cropping cycles. The experiments were conducted using ranodomized complete block design with three replications. Combined analyses of variance were performed for grain yield. The genotype and genotype × year × location effects were significant. Therefore, for more precise evaluation of genotype by environment interactions and grain yield stability, parametric and non-parametric analysis methods such as AMMI, rank and standadard deveiation (SD) of rank, coefficient of environmental variation was employed. Results of all three stability analysis methods showed that genotypes no. 3 and no. 4 with high grain yield (8650 and 8699 kg.ha-1, respectively) and low G × E interaction were adapted with grain yield stability durum wheat genotypes. These superior durum wheat genotypes were identified for being released as new commercial durum wheat cultivars for temperate agro-climatic zone of Iran.

Evaluation of genotype × environment interaction in durum wheat (Triticum turgidum var. durum L.) regional yield trials

The objective of this experiment was to analyze genotype × environment (GE) interaction for grain yield of 20 durum wheat genotypes to identify the yield stability and adaptability of genotypes using GGE biplot method as well as some univariate stability statistics. The genotypes were evaluated in three rainfed stations of Sararood (Kermanshah), Maragheh and Shirvan, Iran under both rainfed and...

Evaluation of Grain Yield Stability of Durum Wheat Genotypes Using Parametric and Non-Parametric Methods

Durum wheat (Triticum turgidum L.), like most other crops, is affected by various stresses. Therefore, cultivars that, in addition to the ability to produce higher yields, can maintain their yield potential in different years and locations are considered superior cultivars. In order to obtain high-yielding and stable genotypes of durum wheat, 16 lines with two control cultivars Dehdasht and Sey...

Variations of Grain Yield and Agro-Morphological Traits of Some Promising Durum Wheat Lines (Triticum turgidum L. var. durum) at Zinc Sufficient and Deficient Conditions

Successful production and development of stable and adaptable genotypes only depend on the positive results achieved from the interaction between genotype and environment that consequently has a significant impact on breeding strategies. In this regard, we conducted an experiment to study genotypic differences of 16 lines durum wheat under both zinc sufficient and deficient stress during 2014-2...

Traits Explaining Durum Wheat (Triticum turgidum L. spp. Durum) Yield in Dry Chilean Mediterranean Environments

Yield under water stress (YS) is used as the main criterion in the selection of wheat varieties for dry Mediterranean environments. It has been proposed that selection of genotypes using YS assisted by morphological and physiological traits associated with YS is more efficient in selecting high yielding genotypes for dry environments. A study was carried out at the Antumapu Experiment Station o...

TThe existence of genotype– environment interaction requires that the performance of genotypes be tested in a wide range of environmental conditions so that the resulting information can increase the efficiency of their selection and introduction. For this purpose, this study using 11 selected lines from uniform national experiments, along with control figures of Saral and Anna and two advanced...
