FIELD: agriculture.
SUBSTANCE: sunflower seeds have been genetically modified with the help of two cycles of artificial induction of mutations, in each case with further identification of mutant species, which bore required criterion. Modified seeds are characterised by the fact that 26-80% of tocopherols are present in them in the form of delta-tocopherols. This level of delta-tocopherols is determined by genotype of seeds modified by this criterion and is independent on conditions of cultivation. From seeds they grow genetically modified plants of sunflower, which produce seeds with high levels of delta-tocopherol as a result of self-fertilisation.
EFFECT: oil is extracted from seeds with high concentration of delta-tocopherol.
