The Determination of Oil Content and Fatty Acid Compositions of Domestic and Exotic Safflower (Carthamus tinctorius L.) Genotypes and Their Interactions

Burhan Arslan    

Abstract: This study was carried out to determination of the differences and interactions between oil content and fatty acid of safflower cultivars. The experiments were arranged in randomized blocks experiment design with three replications in Van, Turkey. Three domestic (cvs of Yenice, Dinçer and Remzibey) and eight exotic cultivars (Centennial, GW9003, GW9005, GW9022, GW9023, Montola 2000, Montola 2001 and C9305) were grown in Van in 2000 and 2001. The results of variance analysis showed that the differences of oil content and fatty acid of cultivars were significant. The highest oil content was obtained from cvs. Montola 2001 and Montola 2000 (35.3 and 35.2%, respectively), while the lowest oil content was obtained from cv. Centennial (29.0%). In addition to, safflower cultivars were determined about 4.1 to 7.9%, palmitic acid, 1.1 to 4.6% stearic acid, 0.0 to 0.4% arachidic acid, 0.0 to 0.3% palmitoleic acid, 15.6 to 81.4% oleic acid, 7.2 to 77.3% linoleic acid and 0.1 to 1.2 % linolenic acid. The oil stability (18:1/18:2) of varieties ranged 0.20-0.30 in linoleic cultivars, 5.34-11.3 in oleic cultivars. On the other hand, positive and significant relationships were determined between oleic acid and palmitic acid (r = 0.317**), oil stability (r = 0.920**), while the greatest negative and significant relationship was found between oleic acid and linoleic acid (r = -0.999**).
