Abstract

The invention relates to a seedling breeding method using asparagus spores. The method comprises the steps of (1) spore collection, (2) indoor cultivation and (3) sea area hanging cultivation and period control. The seedling breeding method using the asparagus spores has the advantages that provenances needed by large-area popularization can be obtained effectively; indoor storage of asparagus during summer is achieved; seedling breeding is high in stability and strong in controllability; cost and labor and material consumption caused by north-to-south transfer and south-to-north transfer are effectively reduced; compared with vegetative propagation, generative propagation of seedlings has the advantages of being capable of breeding a large number of seedlings with different genetic backgrounds, selectively cultivating seedlings adaptable to different sea areas, and easing idioplasm degeneration to a certain degree; improved variety screening during asparagus breeding work is accelerated.

Description

technical field

[0001] The invention relates to a breeding method of marine algae, in particular to a breeding method of asparagus spore seedlings. Background technique

[0002] At present, asparagus is cultivated by means of vegetative propagation through clipping seedlings of algae. In the long-term cultivation process, some problems are faced: one breeding seedling is single, and genetic variation and germplasm degradation are caused by the harsh environment of the sea area. The excellent traits of the parent cannot be maintained; 2. The problem of the source of improved seeds required for large-scale promotion. The seedlings required for cultivation are directly taken from the float method plus the harvested algae, accounting for about 20-30% of the total output, and reducing the benefits of cultivation; Due to the limitation and lack of sources, some people have proposed the strategy of indoor summer and cold storage preservation, but the indoor space and labor costs o...
