Sunflower plants, seeds capable of forming the same, and a novel endogenous vegetable oil derived from such sunflower seeds are provided. The plants have the ability to yield an endogenous vegetable oil wherein the levels of palmitic acid and oleic acid are provided in an atypical combination via genetic control. The concentration of palmitic acid in the endogenous oil constitutes at least 20 (e.g., approximately 20 to 45) percent by weight of the total fatty acid content, and the concentration of oleic acid in the oil constitutes at least 45 (e.g., approximately 45 to 65) percent by weight of the total fatty acid content in the absence of hydrogenation or other chemical or physical modification. It was found that the plants of the present invention can be formed through the combination (as described) of genetic determinants that were found to be present in the Pervenets sunflower and the H-55-9-2-1 or H-55-9-2-2 sunflower. The novel endogenous oil of the present invention is particularly useful, inter alia, in the production of margarine, or a cocoa butter equivalent.
An endogenous vegetable oil derived from Helianthus annuus seeds which exhibits in the absence of hydrogenation or other chemical or physical modification (1) at least 20 percent by weight of palmitic acid based upon the total fatty acid content, and (2) at least 45 percent by weight of oleic acid based upon the total fatty acid content, which oil was extracted from seeds possessing genetic means for the expression of the stated fatty acids in the stated concentrations.
An endogenous vegetable oil derived from Helianthus annuus seeds which exhibits in the absence of hydrogenation or other chemical or physical modification (1) approximately 20 to 45 percent by weight of palmitic acid based upon the total fatty acid content, (2) approximately 4 to 15 percent by weight of palmitoleic acid based upon the total fatty acid content, (3) approximately 45 to 65 percent by weight of oleic acid based upon the total fatty acid content, and (4) approximately 1 to 10 percent by weight of linoleic acid based upon the total fatty acid content, which oil was extracted from seeds possessing genetic means for the expression of the stated fatty acids in the stated concentrations.
