Ethiopian barley landraces show higher yield stability and comparable yield to improved varieties in multi-environment field trials

Graphical Analysis of Multi-Environment Trials for Barley Yield Using AMMI and GGE-Biplot Under Rain-Fed Conditions

The AMMI and SREG GGE   are among the models that effectively capture the additive and multiplicative components of genotype × environment interaction (GEI) and provide meaningful interpretation of multi-environment trials’ data set in the breeding programs. The objective of this study was to assess the effect of GEI on grain yield of barely advanced lines and exploit the positive GEI effect us...

Evaluation 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...

Photosynthetic Efficiency in Juvenile Stage and Winter Barley Breeding for Improved Grain Yield and Stability

Different winter barley cultivars showed various levels of genetic tolerance when they were exposed to different stress conditions. Therefore, investigations of interaction among genotypes (cultivars) and environments give useful information concerning yield stability and quality in barley (Blum, 1989; Ceccarelli et al., 1998, 2000; Lalić et al., 2007, 2009). Drought conditions frequently give ...

Linkage disequilibrium mapping of yield and yield stability in modern spring barley cultivars.

Associations between markers and complex quantitative traits were investigated in a collection of 146 modern two-row spring barley cultivars, representing the current commercial germ plasm in Europe. Using 236 AFLP markers, associations between markers were found for markers as far apart as 10 cM. Subsequently, for the 146 cultivars the complex traits mean yield, adaptability (Finlay-Wilkinson ...
