Method for breeding new species by fusion between various plants and distant induced mutagenesis
A technology for new varieties and plants, which is applied in the field of mutual fusion and distant mutation of different species of plants to cultivate new varieties. It is difficult to select breakthrough varieties and other problems, so as to achieve the effects of fast and stable offspring traits, high scion utilization rate, and large leaf area

Embodiment 1
[0031] The method of the present invention is as follows: choose potato to make rootstock, and wheat is made scion; When potato grows 6-8 new leaves after planting 30 days, the soil around the root is scraped open, on the stem of 1.5cm above the root or the block below the root Prick a small hole with a bamboo stick; the wheat is pre-germinated, and when it grows to 10 cm and has 4-5 leaves, remove the root completely with a blade, insert it into the small hole of the rootstock, and then use moist soil with a water content of 60%. Cover the incision and the scion lightly. After 10-15 days, the scion and the rootstock are completely fused and start to grow. Keep the temperature at 10-25°C, and the scion absorbs nutrients through the rootstock to maintain life. After 20-25 days, the scion will grow a new one on the upper part of the fusion. The root grows into the ground and it is determined that the distant mutation is successful; 30 days later, the wheat starts to tiller, cut o...
Embodiment 2
[0036] The method of this embodiment is as follows:
[0037] Using the method of seed bud fusion, sweet potato is used as the rootstock and millet is used as the scion. When the sweet potato grows to 10-16 new leaves after 40-60 days of planting, the soil around the root is removed, and the root is 1.5cm above the root. On the block below, pierce a small hole with an iron nail or a bamboo stick; the millet is pre-germinated, and when it grows to 4 leaves, remove the root completely, insert it into the small hole of the rootstock, and then use moist soil with a water content of 70%. The incision and the scion are covered lightly. After 15-20 days, the scion and the rootstock are fully fused, and the scion begins to grow and absorb nutrients through the rootstock to maintain life. Within 20-30 days, the base of the stem will take root and enter the soil, the main stem of millet and the main stem of sweet potato will be completely integrated, and the long leaves on the stem of sw...
Embodiment 3
[0041] The method of the present embodiment comprises the following steps:
[0042]Use potatoes as rootstock and soybeans as scion. When potatoes are planted 40-60 days later, when the stem length reaches 30-50cm and 5-10 new leaves, remove the soil around the root and place it on the stem 1.5cm above the root or below the root. Prick a small hole on the block with iron nails or bamboo sticks; soybeans are germinated in advance, and when the height reaches 8-10cm and 4 leaves, after the root is completely removed, the lower part of the stem is cut into a wedge shape and inserted into the small hole of the rootstock. Then cover the incision and the scion gently with moist soil with a water content of 65%. After 15-20 days, the scion and the rootstock are fully fused, and the scion begins to grow and absorb nutrients through the rootstock to maintain life. Within 20-30 days, the base of the stem will take root and enter the soil, the main stem of soybean and the main stem of pot...
