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...
متن کاملParameters of AMMI Model for Yield Stability Analysis in Durum Wheat
Th e improvement of new genotypes with acceptable yield stability in diff erent environments is an important issue in breeding programs. In order to study genotype × environment (GE) interaction and to determine the most stable durum wheat genotypes, fi eld experiments were conducted with 20 genotypes for three years (20072009). Results showed highly signifi cant GE interaction indicating the p...
متن کاملIdentification of the Most Stable Durum Wheat Genotypes Using Nonparametric Yield Stability Statistics
Durum wheat (Triticum durum desf.) is one of the most important cereal crops used to make pasta, macaroni and other foods. Understanding the complexity of the genotype × environment interaction (GEI) and its impact on determining the most stable genotypes, mega environments and other adaptation goals has been a special concern for the plant breeders. Various methods exist for the stability anal...
متن کاملEvaluation of Genotype × Environment Interaction and Determining Grain Yield Stability of Durum Wheat Genotypes in Uniform Regional Yield Trials in Semi-Warm Rainfed Areas
There are different methods for study the genotype × environment interactions and determining stable genotypes such as parametric, non-parametric and multivariate methods. In this research, 19 selective genotypes from advanced trials of durum wheat at 2011-2012 agronomic year, have been cultivated with Dehdasht check cultivar for three growing years (2012-2015) in five locations (including Gach...
متن کاملParametric model based assessment of genotype×environment interactions for grain yield in durum wheat under irrigation
The objectives of this study were to assess the genotype (G) by environment (E) interaction of grain yield of durum wheat(Triticum durum Desf.) based on parametric models, additive main effects and multiplicative interaction (AMMI) and joint linear regression models; and compare the relative efficiency of the two models in explaining the GE effects. Twenty-three genotypes were evaluated across ...
