Problems solved by technology

[0014] The purpose of the present invention is to propose a method of rapidly cultivating whole asparagus by using the herbicide balban in view of the current situation that the breeding cycle of asparagus hybrids is too long, super male plants are not easy to identify, hybrid seeds mainly rely on imports, are expensive and difficult to guarantee purity. Method for male strains

Embodiment 1

[0063] 1. Nine hermaphroditic plants were found in the production field of Quanxiong in West Germany, and 6 of them obtained 58 mature seeds after selfing and artificial pollination.

[0064] 2. Asparagus seeds first use 30ml 50mgl in a flask -1 Soak in the Barr plate solution for 8-10 hours; put three layers of filter paper in a petri dish, add 20ml of Barr plate solution, wrap the asparagus seeds with two layers of gauze, and cultivate them under light at 25°C for 12 days with a light intensity of 54.2 μmol -1 m -2 the s -1 , the photoperiod is 12 hours, the seeds are washed in clean water for 10-15 minutes after germination, and then sowed.

[0065] 3. Seedlings are grown after sowing, and most of them will bloom after about 35 days, with a flowering rate of 58.7%. Male plants and female plants are distinguished according to the flower type. Results The ratio of male plants to female plants was 21:6, which was higher than the expected ratio of 3:1. It shows that under t...

Abstract

The invention discloses a method utilizing herbicide Barban to rapidly cultivate asparagus all male plants strain, which comprises the following steps: 1) amphoteric strain is chosen from the asparagus varieties for production purpose; the amphoteric strain produces asparagus seeds by homologous strain inbred; 2) the asparagus seeds are soaked in Barban, and bud forcing treatment is carried out to the asparagus seeds; 3) the processed asparagus seeds are cultivated in a nutrition pot; flowering takes place after 30 to 35 days; each individual plant respectively hybrid with a female strain, and the seeds of each individual plant are reserved; 4) the seed reserved from each individual plant are processed again by Barban; after flowing, the ratio of male and female flowering is calculated, and super male plants are identified; 5) super male plant clones are reserved and propagated by in vitro culture method; 6) the super male plant is used as the male parent to hybrid excellent female line, and asparagus all male plants strain can be acquired. The method has the advantages that, the time of asparagus from seedling to flowering is greatly reduced; the identification process of super male plants is accelerated; the invention has an important role in the breeding of asparagus all male plants strain, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of crop variety breeding. Specifically, the invention relates to a technique for breeding all-male asparagus varieties, in particular to a method for quickly cultivating all-male asparagus varieties by using the herbicide balban. Background technique [0002] The scientific name of asparagus is Asparagus officinalis L. It is a perennial herbaceous plant of the genus Asparagus in the family Liliaceae. It is eaten with fresh tender stems. The proportion is right, the medicinal value is long and widely used.
