Problems solved by technology

[0005] As two plants with far-reaching kinship, wheat and potato have huge differences in anatomical structure, different physiological characteristics and metabolic pathways, and poor somatic cell affinity, which makes it difficult for the contact surface between rootstock and ear to fuse. For example, using conventional grafting methods , the operation is extremely difficult, the survival rate of the sc

Example Embodiment

[0023] Next, in connection with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clear and completely, as will be described, as described herein is merely embodiments of the invention, not all embodiments. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0024] Using the long-term symbiotic and apparent genetic cultivation of the six-fold full purple purple wheat technology, including the following:

[0025] S1, choose the healthy seeds of wheat suitable for local climate and purple potato stems;

[0026] S2, the wheat after spring is placed into a low-temperature bud box, and the seedling culture is carried out in ordinary soil;

[0027] S3, place healthy purple potato stems in the greenhouse, standing around 1cm, at 1 cm near the bud, vertical in diameter 1.5mm drill, depth into the potato tuber 2 ...

Abstract

The invention relates to the technical field of crop breeding, and discloses a technology for cultivating hexaploid all-purple-grain wheat by using distant symbiosis and epigenetic inheritance. According to the technology, after rootstocks are subjected to straight drilling at positions around bud eyes, and then rooted wheat germ scions are directly inserted, so that the fit of the scions and rootstocks are in an artificial stress with light control, temperature control and humidity control; the physiological and metabolic differences between the rootstocks and the scions in active differentiation and growth states are forced to be reduced, some physiological functions are stimulated, section fusion is accelerated, and a material and information communication channel is established; scion cells can gradually receive genetic materials corresponding to beneficial characters of the rootstocks as well as regulation and control hormones and obtain beneficial epigenetic characters before and after calluses are generated, and finally fertile seeds with special economic values are generated; and compared with a traditional breeding mode, through the technology, under the condition that nuclear chromosomes are not changed, new characters which are difficult to generate in traditional breeding can be rapidly obtained, the breeding period is shortened, and the efficiency of improving crop varieties is improved.

Description

technical field [0001] The invention relates to the technical field of crop breeding, in particular to the technology of cultivating hexaploid whole purple wheat by means of distant symbiosis and epigenetic inheritance. Background technique [0002] Purple potato is a kind of characteristic potato rich in anthocyanins, and the basic structure of anthocyanins is flavonoid core structure, which is characterized by polyphenolic hydroxyl groups, so that anthocyanins have the property of scavenging free radicals, so they have a variety of biological active. Anthocyanins have biological activities such as anti-tumor, anti-aging, anti-oxidation, anti-mutation, anti-cancer, anti-atherosclerosis, and prevention of senile degenerative diseases. It also plays a very important role in protecting the liver and stomach. Therefore, in order to increase the intake of anthocyanins (note: the hydrolyzate of anthocyanins is anthocyanins) in the daily diet, it is necessary to use the character...
