Evaluating of the promising genotypes in different years and locations would aim to identify stable and adaptable genotypes with high yield potential. For this purpose, three genotypes of rapeseed derived from crossing of three varieties named Foseto, Option 500 and Goliath were planted with check variety (Hyola 401) in three locations (Sari, Behshar and qarakheil) using randomized complete block design with 3 replicates from 2012 to 2014 cropping season. Results indicated that the average of grain yield in three genotypes in three locations were as follows: 5616 kg.ha-1 for genotype 43 in Sari, 3871 kg.ha-1 for genotype 43 in Behshahr and 3550 kg.ha-1 for genotype 29 in qarakheil. The yield of these genotypes was higher or did not have significant difference than check variety (Hyola401). Generally using stability analysis and yield mean, it can be suggested that genotype 43 with the least stable and high yield in Sari and Behshar is a good candidate for these regions. In addition, genotype 29 with good general adaptation and next priority, 28 with average general adaptation are suitable candidates for all three locations.
