specific Embodiment approach 1

[0032] Specific embodiment 1: a kind of rapid breeding method of sugar beet in the present embodiment, the specific operation steps of this method are as follows:

[0033] (1) Sowing the coated beet seeds in a nutrient bowl, placing them in an incubator with a temperature of 20° C., cultivating them for 7 days, and the seedlings are unearthed;

[0034] (2) After the seedlings are unearthed, move the nutrient bowl to the cultivation room for cultivation. The cultivation conditions in the nutrient chamber are temperature 20°C and light intensity 200μmol·m -2 ·s -1 , photoperiod 14 / 10h, relative air humidity 20%, cultivated in the cultivation room for 3 weeks, the first pair of true leaves of sugar beet seedlings fully unfolded, as figure 2 shown;

[0035] (3) If figure 1 As shown, the sugar beet seedlings were moved into the cold storage for vernalization treatment, the temperature of the cold storage was 4°C, and the light intensity was 100 μmol·m -2 ·s -1 , the light cyc...

[0037] Specific embodiment 2: a kind of rapid breeding method of sugar beet in the present embodiment, the specific operation steps of this method are as follows:

[0038] (1) Sowing the coated sugar beet seeds in a nutrient bowl, placing them in an incubator at a temperature of 20° C., cultivating them for 7 days, and the seedlings are unearthed;

[0039] (2) After the seedlings are unearthed, move the nutrient bowl to the cultivation room for cultivation. The cultivation conditions in the nutrient chamber are temperature 20°C and light intensity 200μmol·m -2 ·s -1 , the light cycle is 14h / d, the relative air humidity is 20%, and the cultivation room is cultivated for 3 weeks. The first pair of true leaves of sugar beet seedlings are fully expanded, as figure 2 shown;

[0040] (3) If figure 1 As shown, the sugar beet seedlings will be moved into the cold storage for vernalization treatment, the temperature of the cold storage is 4°C, and the light intensity is 100 μmol·m ...

Abstract

The invention discloses a quick breeding method of beet, belongs to the technical field of plant propagation breeding and aims to solve the problem that existing beet breeding is long in period and the problem that extra breeding cost generated by cultivation of mother roots in different places. A vernalization treatment target is changed from the beet mother roots to beet seedlings, so that timeand cost needed for mother root cultivation are saved, beet breeding period can be saved effectively; the beet seedlings start bolting in 7-30d after transplanting generally, seeds can be harvested only 2-4 months of growth, the whole process does not involve different-place cultivation step, and it takes 5-8 months from primary beet seeds and offspring beet seeds. Compared with conventional breeding, the method has the advantage that breeding period can be shortened by 10 months; compared with off-season breeding, the method has the advantage that breeding period can be shortened by about 4 months; the method does not involve the problem of different-place cultivation, so that cost can be saved.

Description

technical field [0001] The invention relates to a rapid breeding method of sugar beet, which belongs to the technical field of plant breeding and breeding methods. Background technique [0002] Sugar beet, Chenopodiaceae, is the main sugar crop in the three northern regions of my country, and it is also one of the most competitive and potential economic crops in the north. It has the advantages of complete sugar beet cultivation technology system, and the whole process of planting and harvesting can be mechanized. The land utilization rate for planting sugar beet is high, and the yield of sugar beet per mu can still reach more than 2 tons in mild to moderate saline-alkaline land, and it does not compete with staple food for land, taking into account ecological benefits. By-products such as beet molasses, betaine, and beet red pigment have high economic value and development potential. [0003] Because sugar beet is a biennial plant, the first year of growth is mainly the v...
