Embodiment 1

[0050] Embodiment 1 provides a kind of tartary buckwheat hybrid breeding method, comprises the following steps:

[0051] Parental material: The high-stalk and high-yield variety "Hokuriku No. 4" selected from the "Rotudatum" introduced by the Agricultural Bioresources Research Institute of the Ministry of Agriculture, Forestry and Fisheries in Japan's Hokuriku Agricultural Experimental Field was used as the female parent, and the short-stalked and low-yield local variety "Stone Buckwheat" is the male parent.

[0052] The main characters of the male and female tartary buckwheat were studied, and the results are shown in Table 1 (mean value).

[0055] Seedling raising and planting of the parents: fill about 2 / 3 of the cultivation soil in the 30*28cm nutrient bowl at the beginning of March and pour water thoroughly, and make 3-5 seedlings with a diameter of about 1cm and a dept...

Embodiment 2

[0075] Embodiment 2 provides a kind of tartary buckwheat hybrid breeding method, comprises the following steps:

[0076] Parental materials: The high-yield variety "Beixi No. 2" selected from "MT-1" introduced from Russia by the Hokuriku Agricultural Experimental Field in Japan is the female parent, and the short-stalked and low-yield local variety "Stone Buckwheat" in Hokkaido is the male parent.

[0077] Research the main character of described male parent and female parent tartary buckwheat, its result is shown in following table 3 (mean value).

Abstract

The invention discloses a tartary buckwheat crossbreeding method. The tartary buckwheat crossbreeding method comprises the steps of selecting two tartary buckwheat varieties with relatively large target character difference as a male parent and a female parent respectively, cultivating the male parent tartary buckwheat until entering an initial flowering stage, cultivating the female parent tartary buckwheat until more than five or more than flower buds with the size of 1.5-2 mm are exposed from the top, and starting hybridization; selecting unpollinated flower buds of robust plants from the cultured female parents for castration; and selecting flowers with cracked anthers and more pollen attached to the surfaces from the cultivated male parents for pollination, carrying out bagging for continuous cultivation, harvesting seeds of the female parent plants, and thus obtaining the tartary buckwheat hybrid seeds. Through a tartary buckwheat bud castration artificial hybridization technology, a tartary buckwheat hybrid variety which is high in yield, high in stress resistance, wide in adaptability, excellent and high in yield is bred.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a tartary buckwheat hybrid breeding method. Background technique [0002] Tartary buckwheat (F.tataricum Gaertn) belongs to the Polygonaceae (Polygonaceae) Buckwheat genus (Fagopyrum Mill) crops, its grain content of protein, vitamins, fat and other nutrients is generally higher than that of rice, wheat and corn, etc., and tartary buckwheat also contains Some special nutrients and medicinal ingredients that are absent or scarce in other food crops (such as rutin, VC, bitters, chlorophyll, Se, etc.) can not only increase the content of essential elements in the human body, but also play an auxiliary role in the treatment of heart and brain. Vascular disease, high blood pressure, diabetes, cancer and medical effects such as clearing away heat, detoxification and anti-inflammation. As the health function and medicinal value of tartary buckwheat are gradually recognized by peo...
