Embodiment 1

[0028] In an embodiment of the present invention, a kind of grape breeding method comprises the following steps:

[0029] (1) Seed selection: the pollen of Zeshan No. 2 grape was pollinated on the flower spike of the female parent Victoria grape, and the pollinated flower spike was covered with a paper bag, and the fruit with good properties was selected after the fruit matured;

[0030] (2) Improve activity: put the obtained grape seeds in a drying box for 2 days, adjust the temperature of the drying box to 65°C, passivate the virus on the surface of the seeds, make them lose their vitality, and increase the vitality inside the seeds to promote The seeds germinate neatly and uniformly;

[0031] (3) Acceleration of germination: spread the treated grape seeds between two layers of non-woven fabrics, and set 8 cm thick wet sand above and below the two layers of non-woven fabrics, and place them in the shade for 50 days. Soak the seeds in water for 18 hours in the first 8 days, ...

Embodiment 2

[0038] In an embodiment of the present invention, a kind of grape breeding method comprises the following steps:

[0039] (1) Seed selection: the pollen of Zeshan No. 2 grape was pollinated on the flower spike of the female parent Victoria grape, and the pollinated flower spike was covered with a paper bag, and the fruit with good properties was selected after the fruit matured;

[0040] (2) Improve activity: put the obtained grape seeds in a drying box for 2.5 days, adjust the temperature of the drying box to 70°C, passivate the virus on the surface of the seeds, make them lose their vitality, and increase the vitality inside the seeds to promote The seeds germinate neatly and uniformly;

[0041] (3) Acceleration of germination: spread the treated grape seeds between two layers of non-woven fabrics, and set 9 cm thick wet sand above and below the two layers of non-woven fabrics, and place them in the shade for 60 days. Soak the seeds in water for 24 hours in the first 10 day...

Embodiment 3

[0048] In an embodiment of the present invention, a kind of grape breeding method comprises the following steps:

[0049] (1) Seed selection: the pollen of Zeshan No. 2 grape was pollinated on the flower spike of the female parent Victoria grape, and the pollinated flower spike was covered with a paper bag, and the fruit with good properties was selected after the fruit matured;

[0050] (2) Improve activity: put the obtained grape seeds in a drying box for 3 days, adjust the temperature of the drying box to 75°C, passivate the virus on the surface of the seeds, make them lose their vitality, and increase the vitality inside the seeds to promote The seeds germinate neatly and uniformly;

[0051] (3) Acceleration of germination: spread the treated grape seeds between two layers of non-woven fabrics, and set 10 cm thick wet sand above and below the two layers of non-woven fabrics, and place them in the shade for 70 days. Soak the seeds in water for 30 hours in the first 12 days, ...

Abstract

The invention discloses a grape breeding method, comprising the following steps: (1) Seed selection: pollen of Zeshan No. (2) Improving activity: put the obtained grape seeds in a drying box, and adjust the temperature of the drying box to 65-75°C; (3) Acceleration: Accelerate germination until the seed shell cracks and turns white; (4) Raise seedlings: Put the (5) Pruning; (6) Selection of seedlings; (7) Water and fertilizer management; (8) Collection of branches: before winter, select branches with a length of 10-20cm and a diameter of 15-20mm. Carry out sand culture cellar and overwinter, and these branches are seedlings in the second spring. The grape fruit cultivated by the invention is large, the weight of a single particle can reach 10 g, and the overall disease resistance is strong, the fruit is not easy to fall off, and is suitable for long-distance transportation and storage, and the plant of the invention has the performance of cold resistance and cold resistance.
