Evaluation of Grain Yield Stability in Some Selected Wheat Genotypes Using AMMI and GGE Biplot Methods

Wheat Triticum aestivum L. is one of the most important agricultural products, and meets highest nutritional needs humans in various countries. This study aims to evaluate compatibility stability 25 wheat genotypes for two crop years five regions (Karaj, Qazvin, Isfahan, Varamin Damavand) a randomized complete block design with three replications. The results variance analysis additive main effects multiplication interaction (AMMI) method showed that effect genotype × environment first, second, mean had significant difference at level percent probability. Based on obtained from first second principal components, G8, G4 G22 were identified as superior genotypes. Isfahan was an ideal this study. comparison Duncan G14, G12, G1 suitable ranks. Graphical used environment, interaction. ranking components average years, G2 G21 high yielding, stable. G18 G23 selected best all experimental periods, based multidimensional diagram. diagram G12 genotypes; diagram, Damavand environments environments. AMM1 covered 69.6% AMMI2 75.6% data year experiment. In year, 78.1% total explained AMMI1, 71.1% AMM2.
