Embodiment 1

[0022] (1) The pure-line fine-bred filamentous germplasm is cultivated in the seedling pond of provenance isolation, and the conchospore seedlings are collected after the filamentous seedlings are mature;

[0023] (2) Pure-line fine seed seedling nets are cultivated in isolated sea areas to restore reproductive habits, and cultivated until the algae mature to form male and female germ cells.

[0024] (3) Collect mature algal bodies on the net of the pure-line fine-bred cultivation, which is the fine-bred F 1 Substitute algae;

[0025] (4) Wash the seed algae with clean seawater, dehydrate, dry in the shade or store at -20°C, and then it can be used for cultivating fine seedlings.

[0026] (5) It is the popularized improved variety F that is used to collect fruit spores and carry out seedling cultivation 1 Substitute algae.

[0027] In the step (1), the cultivation of fine-bred filamentous seedlings needs to be carried out in a seedling pond where the provenance is isolated,...

Abstract

The invention relates to a method for application and popularization of improved varieties of Porphyra variegata, comprising: (1) the germplasm of pure-line improved filaments, cultivating conch filaments in seedling ponds isolated from provenance, and carrying out ascospores after the filaments mature Picking seedlings; (2) Cultivate pure-line fine seed seedlings in the net sea area, and restore reproductive traits; (3) Collect mature fine-bred F 1 Algae substitutes are used as seed algae; (4) The seed algae are washed with clean seawater, dehydrated, dried in the shade or stored at -20°C for later use, and can be used for collection of productive fruit spores of fine seeds, seedling picking and seedling cultivation. The invention solves the production problems of inoculation of shell seedlings with free filaments of the improved species, difficult control of late ripening measures, low efficiency of picking seedlings of conchospores, and difficult promotion of the improved species, and realizes large-scale seedling cultivation and seed supply of the improved species. This technology makes the application of improved varieties more operable and popular, and promotes the production process of improved varieties of laver.

Description

technical field [0001] The invention belongs to the field of application of improved varieties of laver, and in particular relates to a method for application and popularization of improved varieties of laver. Background technique [0002] Porphyra is a seaweed that grows in the intertidal zone along the coast. ), Porphyra. Seaweed is delicious and has always been the seaweed picked and eaten by coastal people. At present, Porphyra japonica in the south and Porphyra zebra in the north are important economically cultivated seaweeds in my country. [0003] The main production area of ​​Porphyra variegata in my country is located along the coast of Jiangsu Province, and the provenance of cultivated Porphyra comes from wild populations in Qingdao, Shandong. In the traditional method of raising laver seedlings, the cultivator selects algae from the thallus populations of cultivated laver every spring, or collects the original algae from the naturally distributed wild populatio...
