Determination of safflower (carthamus tinctorius l.) varieties and lines for winter sowing under Muş conditions

Safflower is an oil plant native to Anatolia, which has the highest oil quality after olive oil. This study was carried out in the winter season of 2023-2024 to determine safflower (Carthamus tinctorius L.) varieties and lines for winter sowing in Muş province having continental climate. The experiment was established completely randomized to coincidence blocks design with theree replications. In the study, seven registered safflower varieties and 13 safflower lines were used. Plant height varied between 65.5-94.7 cm, number of branches per plant 5.6-9.0 pcs/plant, number of trays 5.8-12.0 pcs/plant, number of seeds per tray 24.6-40.2 pcs/tray, tray diameter 19.5-26.2 mm, thousand grain weight 29.4-43.7 g, seed yield 47.8-139.9 kg/da, oil content 15.1-36.3 %, oil yield 9,52-44.9 kg/da were found among the traits examined in the research. According to the results, KYS-3 (139.9 kg/da), ASKON-42 (135.9 kg/da), KYS-4 (124.4 kg/da) and (Yektay 123.7 kg/da) were the best genotypes in terms of seed yield and Yektay variety gave the best results in terms of oil content, but the genotypes with oil content above 30% were KYS-8, KYS-11, Balcı, KYS-4 and Olas, respectively. In terms of seed yield and oil yield per decare for Muş province conditions, Yektay and KYS-4 could be recommended.
