Embodiment

[0051] 1. Collection of breeding female parent Auricularia strains and isolation of Auricularia strains (asexual spores)

[0052] 1.1 Collection of Auricularia fruiting body of breeding female parent and Auricularia strain culture

[0053] The young fruiting bodies of Auricularia aureus collected from Gaoligong Mountain in Fugong were wrapped in absorbent paper and kept sealed at 4°C, and the strains were isolated by tissue separation method within 48 hours. When isolating strains, first sterilize the surface of the fruit body of Auricularia auriculae, and then take 5 × 5 × 5mm 3 A piece of Auricularia fruiting body tissue block of size is inoculated on the Auricularia auricula species culture medium. Golden ear seed medium formula (1L): potato 200g, sucrose 20g, agar powder 20g, KH 2 PO 4 4g, MgSO 4 3g. After inoculation, cultivate in the dark at a temperature of 20°C. After culturing for 25 days, the fruiting body tissue pieces of Auricularia aurantii can be regenerat...

Abstract

The invention belongs to the field of edible fungus breeding, and particularly relates to a tremella aurantialba strain JSJ-X9 suitable for industrial cultivation. The strain has an ITS sequence as shown in SEQ ID NO: 4 and a characteristic sequence of an SCAR marker as shown in SEQ ID NO: 1. The tremella aurantialba strain has excellent and stable production traits and commodity traits, solves the problem of using seeds of tremella aurantialba in industrial cultivation, and has extremely high economic value and application prospect.

Description

technical field [0001] The invention belongs to the field of edible fungus breeding, in particular to a golden ear strain suitable for industrial cultivation. Background technique [0002] Golden ear fungus is a kind of parasitic fungus, which is parasitic on Bacillus chamomile, and the growth of Auricularia mycelium depends on Bacillus chamomile to provide nutrition for it. Auricularia fruiting body is a heterogeneous fruiting body, which is a complex composed of Auricularia mycelia and Mycelia chamoci. [0003] There are few reports on the research on Auricularia species, all of which involve conventional methods of strain propagation, and the description of the quality of the strains only involves the difference between effective strains and invalid strains [1 -3]. Artificial domestication and cultivation of golden ear [4] In the past few decades after the success, the strains were basically isolated from the fruiting body of the wild golden ear, and then continuously ...
