| Abstract/Description: | Introduction Sunflower (Helianthus annuus L.) is an important oilseed crop mainly grown for the production of high quality edible oil. A field study was conducted to understand the dynamics of oil content, various fatty acids and tocopherol content accumulation during maturity in high and low oleic acid sunflower genotypes. Methodology Material: Two high oleic acid content type genotypes (No. 1000 and No. 1002) and two high linoleic acid content type genotypes (DRSF-113 and DRSH-1) Developing seeds of four genotypes were sampled at 3-day interval after 15 days of flowering (DAF). The oil content (%) was measured by Nuclear Magnetic Resonance (NMR) spectroscopy using 20 g oven dried seed samples. Fatty acid profiling was done by Gas Chromatography. Tocopherol analysis was performed on Ultra Performance Liquid Chromatography. Results and Discussion The results indicated that oil content increased up to maturity, but the increase was more pronounced upto 33 DAF in all the genotypes. After 15 DAF, oleic acid content of all the genotypes were comparable (DRSH-1, DRSF-113, No.1000 and No.1002 was 58.89, 67.20, 56.94 and 63.81 %, respectively). Gradual increase in oleic acid and decrease in linoleic acid was observed during maturity in high oleic acid content genotypes (No. 1000 and No. 1002) and continuous decrease in oleic acid and increase in linoleic acid content was recorded in high linoleic acid content genotypes (DRSH-1 and DRSF-113). Palmitic and stearic acid content did not vary at maturity. Sunflower oil, either with high oleic acid or high linoleic acid content, had a tocopherol profile dominated by α‐tocopherol. The α-tocopherol content increased upto 24 DAF, and decreased gradually with seed development in all the genotypes. |
