Problems solved by technology

The color of the fruiting body of Agrocybe argali has also appeared new traits, and the color has changed from brown to white. At present, the genetics of the white variant of the fruiting body of Agrocybe chinensis is not yet clear, and there is no breeding of white varieties of Agrocybe chinensis.

Embodiment 1

[0023] Embodiment 1: A method for breeding white tea tree mushroom, including the following steps:

[0024] 1. Parent selection

[0025] The light gray-brown strains of Camellia Agrocybe Gucha 1, Gucha 2 and White Camellia Agrocybe were purchased from the market (Wang Xiaofan. Analysis of Agrocybe Agrocybe and Application of EST-SSR Markers [D]. Nanchang University, 2012 ).

[0026] 2. Preparation and regeneration of white tea tree mushroom protoplasts

[0027] After the white tea tree mushroom was activated on the PDA solid medium for the second generation, it was transferred to the PDA liquid medium and cultured at 25°C for 5 days. When the hyphae grow around the inoculation block to about 5 mm visible to the naked eye, pick the hyphae mass into a 1.5 mL sterilized centrifuge tube and add 0.5 mL of 0.6 mol / L mannitol, and centrifuge at 4° C., 5000 rpm for 5 min. Remove the supernatant, add 0.5 mL of 2% lysozyme, incubate in a constant temperature water bath at 28°C for 4 hours...

Abstract

The invention belongs to the field of agrocybe cylindracea, and particularly relates to a breeding method for excellent white agrocybe cylindracea. The method comprises the steps that hybridization is carried out on the white agrocybe cylindracea and the agrocybe cylindracea of a pale taupe strain, secondary hybridization is carried out on filial generations and the white agrocybe cylindracea again, and hybrids of the white agrocybe cylindracea can be obtained. The obtained hybrids of the white agrocybe cylindracea carry genes of the agrocybe cylindracea of the pale taupe strain, the excellent character of the agrocybe cylindracea of the pale taupe strain can be inherited to the white agrocybe cylindracea, and therefore the character of the white agrocybe cylindracea is improved.

Description

technical field [0001] The invention belongs to the field of tea tree mushroom, and more specifically relates to a breeding method of fine white tea tree mushroom. Background technique [0002] tea tree mushroom ( Agrocybe cylindracea ) belongs to Basidiomycotina, Phylomycetes, Agaricaceae, Amanitaceae, and it is a kind of woody edible fungus.
