Embodiment 1

[0010] Such as figure 1 , the present invention cultivates steps as follows:

[0011] 1) The golden cauliflower was planted outdoors in October of that year; 2) It was moved indoors at the end of December to add light and heat treatment; 3) It could bloom in advance in January of the following year, and interspecific hybridization was carried out. Pinch off; 4) Harvest the mature seeds in March and dry them in the sun; 5) Cut the skins of the freshly harvested seeds in April, and plant them in a light incubator at 25°C after breaking dormancy, and treat them with 14 hours of light every day; 6) In the same year In June, it is transferred to an outdoor shade place to continue growing; 7) in August, broccoli blooms and sets pods one after another, and mature seeds are harvested before October.

Abstract

The invention belongs to the technical field of plant breeding methods, and particularly relates to a method for breeding and generation-adding of medicago polymorpha. The method comprises the following steps: the medicago polymorpha is planted in a pot outside a room in October of a current year; the medicago polymorpha is moved into the room and subjected to lighting and heating treatment in the end of December; the medicago polymorpha blooms in January of a next year and is subjected to interspecific crossing, and end growth points are pinched off after pods are born; mature seeds are harvested in March and dried in the sun; the just harvested seeds are subjected to peel cutting in April, planted in an illumination incubator at 25 DEG C after dormancy release and illuminated for 14 hours per day; the seeds are transferred to a shade place outside the room for continuous growth in June of the year; the medicago polymorpha blooms and bears pods successively in August and the mature seeds are harvested before October. The method for breeding and generation-adding of the medicago polymorpha, provided by the invention shortens a growth cycle of the medicago polymorpha, breaks dormancy of the medicago polymorpha seeds, and realizes two generations in one year for medicago polymorpha seed breeding.

Description

technical field [0001] The invention belongs to the technical field of plant breeding methods, more specifically, the invention relates to the technical field of annual alfalfa-broccoli breeding and substituting methods. Background technique [0002] Cauliflower (Medicago polymorpha) is an annual or perennial alfalfa, also known as southern alfalfa, seedling grass, grass head, etc., since 1951, Hou Xiangchuan (Hou Xiangchuan, Li Jianxin. Nutritious wild vegetable alfalfa [J]. People's Military Medical. 1951 (05) :5-7) Mr. Jinliu reported in the paper, and analyzed its nutrient composition in detail, the scientific researcher has carried on the continuous report to the green manure effect, feeding value, medicinal value and vegetable value of golden lily. In recent years, with people's attention to food safety, golden cauliflower, as a green organic food, has been increasingly loved by consumers and the government's attention. The market-oriented golden cauliflower industry h...
