Embodiment 1

[0038] The non-seasonal ginkgo forest strawberries from the National Strawberry Germplasm Resource Garden (Nanjing) were taken, planted until the flowering stage, and selfed to obtain the first generation of self-crossed progeny, which was planted in the natural environment.

[0039] Annual observation, screening for continuous flowering and fruiting throughout the year, plant height of 5-30cm, number of inflorescences of more than 5, number of flowers of more than 15, number of fruits of more than 15, fruit weight of more than 2.5g, and fixability of more than 7.0 and conical fruit-shaped target individual plants;

[0040] Selfing, planting and screening were carried out on the obtained target individual plants according to the above method, and more than 18 generations of continuous selfing were selected to select ginkgo strawberries with stable properties, no variation, and fruiting in four seasons. The planting method is as follows: drying the strawberry peel containing th...

Abstract

The invention relates to a breeding and propagation method of everbearing type Baiguo strawberries and belongs to the technical field of strawberry breeding. The breeding and propagation method of the everbearing type Baiguo strawberries includes the following steps that 1, germ plasm of white non-everbearing strawberries is taken for selfing, a selfing first filial generation is obtained, the selfing first filial generation is planted in a natural environment, the selfing first filial generation is observed all the year, and target single plants with target characters are screened; 2, the target single plants obtained in the step 1 are subjected to selfing, planting and screening according to the method in the step 1, the target single plants are continuously subjected to selfing for 18 generations or above, and the everbearing type Baiguo strawberries stable in character and free of mutation are selected out. The obtained everbearing type Baiguo strawberries are stable and free of mutation, can propagate through seeds, and have stable inheritable characters. The obtained strawberry seeds can directly sprout, the sprouting rate is high, and the sprouting rate is not greatly affected when the seeds are saved for 2 years or longer at room temperature.

Description

technical field [0001] The invention relates to the technical field of strawberry breeding, in particular to a method for breeding and propagating ginkgo strawberries bearing four seasons. Background technique [0002] Strawberries are rich in nutritional value and known as the "Queen of Fruits". They are rich in vitamin C, vitamin A, vitamin E, vitamin PP, vitamin B1, vitamin B2, carotene, tannic acid, aspartic acid, copper, strawberry amine , pectin, cellulose, folic acid, iron, calcium, ellagic acid and anthocyanins and other nutrients. [0003] Existing strawberries are basically mature and bear fruit from November to June of the following year, and there are few types that bloom and bear fruit throughout the year; and the existing ornamental strawberries are usually red-fruited strawberries, and there are few ginkgo-fruited strawberries. The production of strawberry seedlings is usually based on asexual reproduction of stolons, and the obtained strawberries have good g...
