Abstract
A sunflower seed is disclosed which has both a high oleic acid content and a low linoleic acid content. Also disclosed is a sunflower seed which has a white or gray seed coat and which contains approximately 80% or greater by weight of olkeic acid. Also described are novel sunflowers for producing the disclosed seed and an oil product derived from the seed.
Claims62
A sunflower seed having an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seed, and a ratio of the amount of linoleic acid in said seed to the amount of oleic acid in said seed of less than about 0.09.
A sunflower seed comprising a white seed coat and having an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seed.
A sunflower seed comprising a gray seed coat and having an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seed.
A sunflower plant which produces seeds that have an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seeds, and a ratio of the amount of linoleic acid in said seed to the amount of oleic acid in said seed of less than about 0.09.
A sunflower plant which is cytoplasmic male sterile and which produces seeds that have an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seeds.
A sunflower plant which comprises a genetic determinant encoding fertility restoration, said plant producing seeds that have an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seeds.
A method for producing a white-coated sunflower seed having an oleic acid content of approximately 80% or greater by weight, comprising the step of crossing (A) a first parent which comprises Pervenets germplasm encoding said oleic acid content with (B) a second parent which comprises a genetic determinant for white seed color.
A method for producing a gray-coated sunflower seed having an oleic acid content of approximately 80% or greater by weight, comprising the step of crossing (A) a first parent which yields white seed with (B) a second parent which produces black seed, at least one of said first and second parents comprising Pervenet germplasm encoding said oleic acid content.
A Helianthus annuus seed product consisting of a substantially homogeneous assemblage of sunflower seeds which has an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seeds.
A sunflower line consisting of a substantially uniform population of Halianthus annuus plants which produce seeds having an oleic acid content of approximately 80% or greater, relative to the total fatty acid content of said seed.
