OIL, seed and sunflower plants with a modified fatty acid distribution in the molecule of triacylglycerol

摘要

1. Sunflower oil directly obtained from sunflower seeds with at least 12% of stearic acid based on total fatty acid content, characterized in that the distribution coefficient of saturated fatty acids α between positions sn-1 and sn-3 is at least 0.38 and the seeds for that produced by the method comprising the steps! a) obtaining seeds which contain an oil having a stearic acid content of at least 12% of the total fatty acid content in the oil; ! b) obtaining seeds that contain oil with a distribution coefficient α higher than 0.38; ! c) crossing plants from the seeds obtained in step a) and b); ! d) collecting the progeny seed harvest F1; ! e) seeding F1 progeny seeds to grow plants; ! f) self-pollination of plants grown in such a way to obtain seed F2; ! g) testing the seeds for the presence of at least a 12% stearic acid content and distribution coefficient α of at least 0.38; ! h) planting seeds with the desired levels of stearic acid content and distribution coefficient α to grow plants; ! i) self-pollination of plants grown in such a way to obtain seed F3; and! j) possibly repeating steps g), h) and i) to secure the required levels of stearic acid content and distribution coefficient α. ! 2. Sunflower oil according to claim 1, characterized in that the distribution coefficient of saturated fatty acids α between positions sn-1 and sn-3 is at least 0.42. ! 3. Sunflower oil according to claim 1, characterized in that the distribution coefficient of saturated fatty acids α between positions sn-1 and sn-3 is
