Kelp breeding method based on gamete selection technology

Abstract

The invention provides a kelp breeding method based on gamete selection technology, which consists of utilizing the superimposition of bisexual reproduction large-scale sea weed sporinite and gamete generation gene expression, selecting gamete (including gametophyte) generation according to breeding destination, thus screening gamete fitting breeding destination, then cultivating sporophyte meeting breeding purpose by utilizing screened gamete in combination with the algae culturing technique. The invention is characterized by the organic integration of laboratory research and sea experiment, wherein the sea cultivation experiment procedure is reduced, which can increase breeding destination and efficiency substantially.

Description

Technical field [0001] The invention relates to an algae breeding method, in particular to a seaweed breeding method based on the technology of gamete selection of bisexual reproductive seaweed. Background technique [0002] Due to the large algae of large economic algae, the complete life history cannot be reproduced in the laboratory. Therefore, breeding research is mainly based on the study of its relatively small gametophytes, through selfing, hybridization, or parthenogenesis. The seedlings are cultivated by developmental methods, and their traits are observed through marine aquaculture experiments. Based on this, combined with the technical methods of biology and genetics to carry out directional genetic improvement work, and cultivate algae varieties that can be used in aquaculture production. The breeding work is mainly a process of later discovery and transformation. For the early stage, that is, the laboratory research stage, it is impossible to predict and infer any va...

Problems solved by technology

Its breeding work is mainly a process of late discovery and transformation. For the early stage, that is, the laboratory research stage, it is impossible to make any prediction and inference about the characteristics of the variety based on the technical means of laboratory analysis, and it is impossible to identify whether the experimentally improved algae plants are compatible with The purpose of the research is the same, and it is necessary to observe and measure the breeding work at sea to confirm whether the breeding work has achieved the expected purpose, and it takes 3-5 years to purify the traits before cultivating the variety

This technical method has been used until now, and its compatibility with algae breeding, especially modern algae breeding technology, has caused problems such as long breeding cycle and low breeding efficiency.
