plagiarism in esl/efl learning contexts has been established as a dynamic and multi-layered phenomenon and has become a topic engaging many researchers in a heated debate in recent years. comparisons of student-generated texts with their source texts have shown that students rely on source texts in their writings and copying is a major strategy used by both l1 and l2 writers. in our country a...

The main purpose of this research was to identify barley promising lines with high grain yield and yield stability for warm region of Iran. In this experiment, 17 barley promising lines and two check cultivars were evaluated in five agricultural research stations; Ahvaz, Darab, Zabol, Gonbad and Moghan, Iran, in 2015-16 and 2016-17 cropping seasons, using randomized complete block design with t...

based on principal component analysis (pca), gge biplot analysis is an effective method to fully assess multienvironmental yield trials (mets). additive main effects and multiplicative interaction (ammi) is an alternative method for assessing phenotypic stability and adaptability. in this research, met data of 14 maize inbred lines were used to perform ammi and gge biplot analyses. these genoty...

The genotype × environment interaction is a major challenge in the study of quantitative characters because it reduces yield stability in different environments and also it complicates the interpretation of genetic experiments and makes predictions difficult. In this regard to analysis of genotype × environment interaction and determine the yield stability of winter rapeseed genotypes in cold a...

In order to determine grain yield stability and yield components in durum wheat, 49 genotypes from International Durum Yield Nursery (IDYN), received from International Research Center for Maize and Wheat Improvement (CIMMYT) with one cultivar as check, were studied in an alpha lattice design with two replications at five locations including Karaj, Darab, Neishabour, Khorramabd and Gonbad. Grai...

genotype×environment interactions (geis) can affect breeding programs because they often complicate the evaluation and selection of superior genotypes. this drawback can be reduced by gaining insights into gei processes and genotype adaptation. the objectives of this research were to evaluate: (1) the yield stability of promising wheat lines across locations and (2) the relationship among the t...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
