Problems solved by technology

However, Lentinus edodes belongs to medium and low temperature type temperature-changing fruity mushrooms. The optimum growth temperature for mycelia is 24-27°C, and the optimum temperature for fruit body development is 8-20°C. If a higher ambient temperature is encountered during production, it will often cause Mycelial death and rod rot

Embodiment 1

[0046] Embodiment 1, the breeding of high temperature resistant shiitake mushroom strain - shiitake mushroom height 16 × buckle 46

[0047] The main cultivars of Lentinus edodes High Temperature No. 8 (referred to as High Temperature 8) and Lentinus edodes Kouxiang (referred to as Kouxiang) were selected as the parent strains for hybrid breeding of high temperature resistant Lentinus edodes hybrid strains. details as follows:

[0048] 1.1 Test strains

[0049] Parental strains: Lentinus edodes High Temperature No. 8 and Lentinus edodes Kouxiang, the parental fruiting bodies with a round shape and 7 minutes of maturity were selected to collect single spores.

[0050] 1.2 Isolation and identification of single spores

[0051]The parental fruiting bodies are suspended in a triangular flask filled with sterile water for 3-5 days, diluted and spread on a PDA plate, cultured at 25°C for 3-5 days, and a single germinated colony is picked for transfer culture, and observed under a m...

Abstract

The invention discloses a high-temperature-resistant shiitake mushroom strain and a cultivation method thereof. The registration number of the high-temperature-resistant shiitake mushroom strain in the General Microbiology Center of China Microorganism Culture Collection Management Committee is CGMCC No.18565. Lentinus edodes high temperature 16 × button 46 is a hybrid strain that can produce mushrooms under high temperature environment and has better agronomic traits than Lentinus edodes high temperature 8 and lentinus cuspidatum through cross breeding with lentinus high temperature 8 and lentinus custard as parents: Its fruiting time was earlier than that of Lentinus high temperature No. 8 and Lentinus edodes, its fruiting body weight was higher than that of Lentinus 8 and lentinus, and its fruiting cap thickness was higher than that of Lentinus 8 and lentinus. The carbohydrate content of the fruiting body was higher than that of Lentinus high temperature No. 8 and Lentinus edodes, the essential amino acid content of its fruiting bodies was higher than that of Lentinus high temperature 8 and Lentinus lentinus, and the fruiting body yield was higher than that of Lentinus 8 and lentinus.

Description

technical field [0001] The invention relates to a high-temperature-resistant shiitake mushroom strain and a cultivation method thereof in the field of biological breeding. Background technique [0002] Lentinula edodes is a kind of saprophytic fungus produced in the temperate and subtropical regions of the northern hemisphere. It is not only rich in nutrition, but also has high health value, and has been loved by people since ancient times. However, Lentinus edodes belongs to medium and low temperature type temperature-changing fruity mushrooms. The optimum growth temperature for mycelia is 24-27°C, and the optimum temperature for fruit body development is 8-20°C. Mycelium dies and fungus sticks rot. The cultivation season of shiitake mushrooms in most parts of China begins in autumn and continues to the spring of the next year. Therefore, in the summer high temperature season, there is often a 3-4 month off-season of market supply. During this period, the price of shiitake...
