Abstract
This study was carried out to determine the ranks of 9 bread wheat (Triticum aestivum L.) genotypes across eleven environments in Central Anatolia, Turkey, in the 2000-2002 growing seasons. Experimental layout was a randomized complete block design with four replications. Analysis of Non parametric stability revealed that genotypes 4 and 8 were most stable and well adapted across eleven environments. In addition, it was concluded that plots obtained by both mean yield (kg ha-1) vs. S1 (1) and mean yield (kg ha-1) vs. S2
(2) values could be enhanced visual efficiency of selection based on genotype x environment interaction.
