“…From our results and also previous studies on safflower, it could be extrapolated that under drought stress, seed yield and as a result oil yield (but not the oil content percentage) of Carthamus species are more affected by drought stress than the other traits. Similar to our findings there are some reports that show oil content is not affected by drought stress or different years [4,20,21]. Also when considering reports that claim oil content change under drought stress [1], we will see that the reduction is not considerable (ranging from 0.4% increase to 4% decrease in 64 single genotypes have been reported in several studies).…”

“…Oleic acid ratio was increased while linoleic acid ratio was decreased in response to drought among all five species. It is reported that linoleic to oleic acid ratio is almost the same at the early grain filling and increases with time in a way that when approaching seed maturity linoleic acid concentration is three times that of oleic acid [4]. Under water-stress conditions, earlier maturity of plants will result in a shorter period of grain filling and as a consequence a shorter time span for conversion of oleic to linoleic acid.…”

“…Whereas, high oleic safflower cultivars contain over 85% oleic acid and the high linoleic safflower cultivars contain 87-89% linoleic acid in their storage oil [3]. Though the genotype is the most important factor that determines the oil content and fatty acid composition, environmental factors such as drought also may affect the oil content and fatty acid composition of the seed [4].…”

“…Developing new varieties of safflower is mainly either for very high oleic acid or high linoleic acid content in the oil (Liu et al, 2016). Our results showed that there was a significant and negative correlation between linoleic acid and oleic acid content, which is in agreement with others' findings (Arslan, 2007; Guan et al, 2008).…”

Wild relatives of safflower (Carthamus tinctorius L.) may contribute genes to improve cultivated species under water stress conditions. This study was conducted to increase genetic diversity of safflower for agromorphological traits and fatty acid profiles using interspecific hybridization. Three species—C. tinctorius, C. palaestinus Eig., and C. oxyacanthus M. Bieb.—were used to develop three segregating populations of C. tinctorius × C. palaestinus (TP), C. oxyacanthus × C. palaestinus (OP), and C. oxyacanthus × C. palaestinus (TO). Seventy‐three lines, along with the three parental species, were evaluated for agromorphological traits under water stress and nonstress conditions in F3 and F4 generations during 2 yr. Fatty acid analysis of interspecific progenies showed occurrence of transgressive segregation. The results showed that mean values of seed yield for TP and TO progenies, where C. tinctorius was one of their parents, were higher than mean value of seed yield for OP that derived from the two wild species. High genetic variation was observed for seed yield, capitulum diameter, and phenological traits in interspecific populations under both moisture conditions. Indirect selection for flowering and seed yield components under water deficit conditions was most efficient to improve seed yield. Results indicated that gene introgression from wild relatives of safflower into the cultivated gene pool increased genetic variation for the measured traits and allowed identifying superior genotypes for future breeding programs.

“…Safflower seeds contain 38%–48% oil, which has 6%–8% palmitic (C16:0), 2%–3% stearic (C18:0), 16%–20% oleic (C18:1), 0.2%–0.4% linolenic (C18:3), and 71%–75% linoleic acids (C18:2) in its composition (Liu, Guan, & Yang, ). SSO has been used to reduce the cholesterol level in the blood and improve glycemia in clinical trials owing to its great quantity of polyunsaturated fatty acids, especially oleic and linoleic acids (Fernandes, Tache, Klingel, Leri, & Mutch, ; Tso, Caldwell, Lee, Boivin, & Michele, ).…”

Three varieties of safflower seed oil (SSO) from Xinjiang Autonomous Region, China, were analyzed by headspace solid‐phase micro‐extraction gas chromatography coupled with mass spectrometry (HS‐SPME‐GC‐MS) to reveal volatile components. Overall, 67 volatile components were determined and four compounds including isoamyl alcohol, caproic acid, n‐pentanal, and heptanal were newly identified in SSO as aroma‐active components. Meanwhile, 16 compounds were selected by relative odor activity value (ROAV) to evaluate contributions of single compounds to the overall odor (ROAV > 1), in which nonanal, (Z)‐6‐nonenal, and (E)‐2,4‐decadienal were the top three contributed substances (ROAV > 70). The sensory panel was described as eight definition terms (grassy, fruity, almond, mushroom, fatty, sweet, paddy, and overall fragrance). Principal component analysis (PCA) revealed a significant separation of three cultivars with the first principal component (PC‐1) and the second principal component (PC‐2) expressing 73.9% and 23.1%, respectively. Both PCA and ROAV allowed identifying the compounds positively correlated to sensory evaluation.
