Özet
In this study; during the spring vegetation period of 2019-2020, fixed and essential oil ratios, their components and, oil yield were determined in 31 black cumin genotypes at advanced yield level, developed by phenotypic recurrent selection method, under in Ankara ecological, fertilizer-free and pesticide-free growing conditions. Fixed oil ratio is determined by the solvent extraction method in the soxhlet device; Its components were determined by gas chromatography. The amount of thymoquinone was determined according to the UV spectrum (PDA). In the two-year evaluation, significant differences were seen between the lines. The results indicate that the USDA-Egyptian population (No. 26) exhibited an average fixed oil content of 34.8%-33.5% in 2019 and 2020, with the highest rate reaching 38.9%. Additionally, the oil yield average from the Burdur genotype (No. 4) was 13.2 kg da-1-12.3 kg da-1, and the highest oil yield recorded was 17.5 kg da-1. Analysis of fixed oil components over the years revealed linoleic acid as a major component at 52.4%, 56.3% and 54.3%, oleic acid at 23.2%, 24.8% and 24.0%, palmitic acid at 10.4%, 12.2% and 11.3%, and stearic acid at 4.3%, 3.2% and 3.7%, respectively. Essential oil results showed variations ranging from 0.01% to 0.08%, with thymoquinone (54.4%-83.1%), p-Cimen (1.0%-16.4%), cis-4-Methoxy thujane (1.8%-5.8%), and longifolene (0.5%-8.5%) identified as the primary components. These results obtained from the study and the high-quality characteristics (ratio and yield) of the naturally grown black cumin plant, reveal the positive impact of good agricultural practices. In addition, the lines that stand out as a result of the research can be used in hybridization studies and can be safely evaluated as a new, multipurpose potential product for pharmaceutical, industrial, and cosmetic uses.
