Embodiment 1

[0024] True Ji mushroom ‘Hy0051’ is a strain obtained from ‘Shennong Baixue’ seafood mushroom purchased in the market by the method of fruiting body tissue separation. (References for fruiting body tissue separation method: Wang Xiuyan, Preparation of edible mushroom parent species by fruiting body tissue separation method, Journal of Chifeng University (Natural Science Edition), 2016, 32(17): 13-14. Ke Lina, Lai Zhibin, etc., Pleurotus eryngii Factory cultivation test of strains isolated from tissue, Jiangsu Agricultural Science, 2015, 43(8):239-241)

[0025] True Jiji mushroom 'Hy0056' is a strain obtained by tissue isolation of white jade mushroom 'B-4' from Tianjin Lvsheng Pengyuan Agricultural Technology Development Co., Ltd. through fruiting body tissue isolation method.

[0026] The main planted mushrooms 'Hy0051' and 'Hy0056' were selected as hybrid parents, and 10 monospore strains with faster growth and more developed aerial hyphae were selected from each of the two ...

Embodiment 2

[0033] Example 2 The SV detection technology was used to compare the DNA difference between this strain and its parent.

[0034] Test materials: 3 strains of jiji mushrooms, among which the strain to be tested is 'Fuhong No. 1', and the 2 control strains are 'Hy0051' and 'Hy0056' respectively.

[0035] Inspection method: According to the genome sequencing data, Kmer subtractive assembly technology is used to obtain differential fragments (SV), and several SV sequences are selected accordingly to design specific primers to amplify the samples to be tested. (For references see Alkan, C., Coe, B. P. & Eichler, E. E. Genome structural variation discovery and genotyping . Nature reviews. Genetics, 2011 (12), 363-376; Fengli Zhu et al., Whole Genome Resequencing Analysis of Korean Chizhi, World Science and Technology-Modernization of Traditional Chinese Medicine, 2019, 21(4)764-774.). SV test primer sequences were synthesized by Qingke Biotechnology Co., Ltd.

Embodiment 3

[0043] The multi-batch pilot test yield results of 'Fuhong 1' showed that 'Fuhong 1' met the requirements of industrial cultivation, and its yield was higher than that of its parents.

[0044] Participating strains: Fuhong 1', 'Hy0056'.

[0045] Test location: Tianjin Binhai Desheng Agricultural Technology Co., Ltd.

[0046] Test arrangement: The strains are uniformly produced, and the test sites are cultivated and managed in accordance with local production management methods.

[0047] Test results: The test found that the hyphae of 'Fuhong 1' were thicker in PDA, the optimum growth temperature was 20°C, and the growth rate was 0.24 cm / d, which was 14 times faster than that of the parents 'Hy0056' and 'Hy0051' % and 7%. The cultivation results of ‘Fuhong 1’ are as follows: image 3 shown.

[0048] Cultivation findings: (1) The time from inoculation to harvest, 'Fuhong 1' was the same as that of the parent; (2) The average yield of 'Fuhong 1' was 230.0 g / bottle, and the av...

Abstract

The invention provides a true jiji mushroom strain Fuhong No. 1, which has been preserved in the General Microorganism Center of the China Microbiological Culture Collection Management Committee on April 29, 2020, and the preservation number is: CGMCC NO.19637. The strain of 'Fuhong 1' has a clustered fruiting body and is not prone to stropharia. The cap is round, the middle and edges are white, the marble pattern is clear, the gills are white, wavy, sparsely dense, and the stipe is white. The quality characteristics of excellent jitake mushroom strains such as , medium solid, and no fluff, and the average fresh mushroom yield of 'Fuhong No. 1' reached 250.0 g / bottle in the productive test, and the small, thin and 'Hy0056' has the disadvantage of thin stipe and has a good promotion prospect.

Description

technical field [0001] The invention relates to a true jiji mushroom strain Fuhong No. 1, which belongs to the field of edible fungi. Background technique [0002] Mushroom [ Hypsizygus marmoreus (Peck) H.E.Bigelow] belongs to Basidiomycotina, Laminomycetes, Agaricaceae, White Mushrooms, and Yuji. Because it has a unique crab flavor, some people call it crab-flavored mushroom, Xiuzhen mushroom, Seafood mushrooms. Fujian Province is the main planting area of ​​Shiji mushroom in southern China. The daily output of Shunchang, Fujian Province has reached 200 tons, and there are 56 seafood mushroom factory production enterprises, accounting for more than 65% of the national daily output. With the expansion of the cultivation scale of shimeji mushrooms, there are different criteria for judging jiji mushrooms in the market, such as the cultivation period, the thickness and pattern of the cap, the thickness and thickness of the stipe, whether it is hollow or not, and the presence...
