Safflower is the only native oilseed crop that is well adapted to different climate conditions of Iran. Omid safflower (Carthamus tinctorius L.) variety with breeding code of line13 received attention during screening of Dryland Agricultural Research Institute safflower collection due to having 38.8 percent oil content in 2011. Studies during three years confirm high oil content in this line. Sixteen selected genotypes were evaluated for adaptation in three agricultural research stations including Sararood, Maragheh and Ghamloo under rainfed condition during two years, 2014 and 2015. Results showed that line13 with 35.7 percent had the highest oil content compared to Faraman check variety with 29.9 percent. Study on oil content and seed yield stability of genotypes through some parametric (Wricke’s ecovalence, superiority measure, geometric mean) and non-parametric measures (Huehn measures, rank mean, rank Si(1)+R ) showed that line13 had the highest oil content stability and in case of seed yield after line LRV51/5 had the highest yield average and yield stability. GGE Biplot showed that line13 was the closest genotype to ideal genotype with the highest oil content and had high distance with other genotypes. On - farm trials conducted in three regions of Kermanshah province under rainfed condition revealed that line13 had the highest oil content and oil yield over three locations. Line13 reaction against safflower rust and fusarium wilt diseases was moderate resistant. Overall, line13 with superiority to other genotypes released as Omid varity for fall planting in semi-cold and early spring planting in the cold drylands of Iran.
