development of new cultivars with high grain yield (gy) stability and good adaptability under both terminal drought stress (tds) and normal irrigation conditions, which plays important role in production of wheat, is one of the major goals of wheat breeding program for cold dry areas of iran. the objective of this investigation was to study the stability and adaptability of gy and genotype × lo...

An important assumption in the analysis of multienvironment cultivar trials is homogeneity of error and genotype 3 environment interaction variances. When variances are heterogeneous, the best estimators of performance are obtained by weighting inversely to variance components. However, because variances are almost never known and must be estimated, the additional error introduced into the mode...

drought stress is one of the most important factors limiting the productivity of crop plants around the world. genotype-by environment (g×e) interactions are common under drought and make breeding progress difficult. for this reason twenty genotypes of bread wheat were evaluated in a randomized complete block design with 3 replications at 2 locations (stress and non-stress environments) in two ...

Cotton fiber quality is defined by several traits, which are affected by genotype×environment interaction (GEI). The objectives of this work were to study GEI of fiber traits, the repeatability and the effect of the size of testing environments in detecting cultivar genetic differences by High Volume Instrument (HVI), and the usefulness of two GEI derived stability indices, σ2i and GGE Instabil...

This study compares the methods of Dunn and Shukla in determining the appropriate insertion length of umbilical catheters. In July 2007, we changed our policy for umbilical catheter insertions from the method of Dunn to the method of Shukla. We report our percentage of inaccurate placement of umbilical-vein catheters (UVCs) and umbilical-artery catheters (UACs) before and after the change of po...
