Investigation of Compatibility and stability assessment of plant cultivars under various environments are of particular interests in crop breeding programs. In this study, stability of 17 spring oilseed rape promising lines was evaluated using GGE biplot analysis. The experiments were carried out in warm southern regions (four locations) of Iran in a randomized complete block design with three replications and in two growing seasons.  The results of GGE biplot analysis indicated G12 is the most stable genotype in two locations where the G14 is stable in other two locations. However, according to average tester coordinate criteria G12 is the most stable genotype across average test environment representing the highest yielding genotype among all investigated genotypes and environments. Based on the mean yield and Shukla Stability Index, as well as Superiority Index, G12, G14 and G18 genotypes are recommended for all warm regions of the country.
 
Keywords: Adaptability, GGE biplot, Ideal genotype, Shukla’s stability index
