Forage shortage and severe water lemitation are the most important factors for livestock and poultry production in the Iran. Releasing a forage safflower variety for drylands of Iran not only produce forage but also reduce the pressure on pastures. Behrang a new safflower variety received attention during screening of safflower collection in 2010 and then introduced by selection. Twenty-four selected spinless genotypes elongwith three check varieties were evaluated in Sararood agricultural research station in 2013 and it was revealed that Behrang was higher than average for seed, wet and dry forage yield and forage quality parameters was suitable in Behrang. Fourteen selected superior genotypes were evaluated during 2015 to 2018 for yield stability and adaptation. Results showed that Behrang with 18345 and 6811 kgha-1 had the highest wet and dry forage yield, respectively, and its rank was the best among all genotypes and results of some stability parameters revealed that Behrang was a stable genotype for wet and dry forage yield. GGE Biplot also showed that Behrang was the closest genotype to ideal genotype with the highest wet and dry forage yield. On-farm trials conducted in Ravansar and Dinavar regions (Kermanshah province) under rainfed condition revealed that Behrang’s wet and dry forage mean yield were 9778 and 5022 kgha-1, respectively, that was higer than Faraman’s wet and dry forage mean yield (8004 and 4269 kgha-1, respectively). Relative feed value (RFV) for Framan and Behrang were 172 and 160, respectively, so both of them determined as high quality for forage use. Behrang reaction against safflower fusarium wilt disease was moderate resistant. Overall, Behrang variety with high wet and dry forage yield and high forage nutrition quality was suitable for fall planting in semi-cold and early spring planting in the cold drylands of Iran.
