In order to evaluate the grain yield stability of 21 oat genotypes, 13 experiments carried out during 6 years (from 2009 to 2015) and across 4 environments in the west of Iran. Five of them were carried out by the author of this thesis during 2013-2015 using a completely randomized block design with three replications under three conditions including irrigated, drought stress and rainfed at the...

Quantifying genotype × environment interaction effect and yield stability under different environmental conditions is very important challenge in plant breeding programs. The aim of this study was to quantify genotype × environment interaction effect on grain yield and grain yield stability of barley promising lines in temperate regions of Iran. Nineteen promising barley lines (G1-G19) along wi...

while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
