Embodiment 1

[0012] Embodiment 1 of the present invention: the breeding method of non-shattering golden buckwheat varieties, at first from Guizhou, Sichuan, Yunnan, Hunan, Guangxi, Tibet, Qinghai, Chongqing and other places, a large number of wild buckwheat different plants and populations are collected in similar Cultivated under different conditions to compare the degree of shattering of different plants. Finally, select the diploid perennial buckwheat with a shattering rate of less than 60%, plant the selected plants in a plot, and allow them to undergo natural hybridization or sexual hybridization under artificial control for pollination and fruiting; and then cultivate the offspring obtained from the hybridization Go to a larger plot, form tens of thousands of isolated populations, select plants with better agronomic traits, higher yield potential and less than 20% shattering rate, and transplant them to a relatively isolated plot ; the seeds of these plants are cultivated to a new is...

Embodiment 2

[0013] Embodiment 2 of the present invention: planting method of non-shattering golden buckwheat variety: seed cultivation method. The first sowing can be done after the end of the late spring frost, and the field should be cleaned, prepared, and boxed according to the usual methods. The width of the box can be set according to your own preference, mainly for the convenience of harvesting. If there is a requirement for mechanized harvesting such as a combine harvester, it can be set up according to the corresponding operation requirements, and a lane for the wheels of the combine harvester to walk is reserved between the boxes. Row sowing is adopted in the box, and the row spacing is 30-50cm. Seeds need to go through a 100ppm gibberellin (920 on the market) solution in a 60°C water bath for 30 minutes to eliminate seed dormancy, and then sow at a distance of 30-50cm; after field cultivation, there is generally no need for a lot of management, mainly for pest control and disea...

Embodiment 3

[0014] Embodiment 3: The planting method of non-shattering golden buckwheat variety: rooting, sprouting and transplanting with stem segments. Before the golden buckwheat seedling stage or full flowering stage, cut the stalks into stems with 2-3 nodes, with the biological upper part facing upwards, prepare 80ppm indole butyric acid solution, soak clean gauze in 80ppm indole butyric acid solution After wetting, spread it on a porcelain plate, put the golden buckwheat stems that have passed through the 80ppm indole butyric acid solution overnight on the above-mentioned gauze, and then cover with the same wet gauze. Or cover it with a cover to keep the humidity and reduce water loss. In 3 days at 25 degrees, the lower nodes of the golden buckwheat stem section can produce fibrous roots, and the upper nodes can sprout new shoots, and they can be transplanted in the field in about 7 days; when transplanting in the field, it is required Water the roots and keep the water supply for 1...

Abstract

The invention discloses a breeding method and planting method of shattering-free wild buckwheat variety. Diploid perennial fagopyrum megaspartanium with a shattering rate smaller than 60% is selected to serve as a material, mutual hybridization is carried out on plants of the fagopyrum megaspartanium, and a variety with a shattering rate smaller than 20% is selected from offsprings after the hybridization to obtain the shattering-free wild buckwheat variety. According to the breeding method and planting method of the shattering-free wild buckwheat variety, cultivation cost is reduced by using a perennation characteristic, shattering-free type wild buckwheat plants are selected to form the new variety through breeding, domestication is carried out on the wild buckwheat which is wild to form a cultivation crop, and standardized cultivation and seed production are carried out. The shattering-free wild buckwheat variety is especially good in drought resistance, barren tolerance and lodging resistance, can be cultivated in barren mountains, covers soil to keep ecological balance, has multiple economic value, and is applicable to production such as vegetables, health protection tea, buckwheat seeds and buckwheat powder.

Description

technical field [0001] The invention relates to the field of agricultural science, in particular to a breeding method of a non-shattering golden buckwheat variety and a planting method thereof. Background technique [0002] The type of buckwheat currently cultivated is common buckwheat (sweet buckwheat, Fagopyrum esculentum Moench) and buckwheat ( Fagopyrum tataricum Gartn.), are annual herbaceous plants whose main purpose is to harvest seeds. Its growth period is short, generally 2-4 months to harvest a season. But the yield is lower. Usually the output of common buckwheat is less than 80Kg / mu, and that of tartary buckwheat is less than 150kg / mu. Moreover, seeds need to be sown every season, and the cultivation cost is relatively high. [0003] Perennial Golden Buckwheat ( Fagopyrum cymosum complex, golden buckwheat complex) is the wild perennial buckwheat type closest to cultivated buckwheat, and can be divided into three species: diploid buckwheat ( F. megasp...
