Embodiment 1

[0029] Example 1 Obtaining Finc-W-62 by hybridization

[0030] The breeding process of the new pure white mushroom strain Finc-W-62 of the present invention comprises the following steps:

[0031] 1) Select parent strains: select TNN-11 and H-W as parents, the fruiting bodies of these two parents can be purchased from the market, and are also preserved in the strain collection center of Shanghai Academy of Agricultural Sciences.

[0032] 2) Preparation of culture medium

[0033] PDA medium: use 200g of potatoes, 20g of glucose and 20g of agar per 1L of medium.

[0034] Original seed medium: 65% wood chips (weight percentage, the same below), 18% rice bran, 7% bran, 10% corn flour, and a water content of 60% to 62%.

[0035] Cultivated species medium: 40% corncob, 24% soybean hulls, 14% rice bran, 17% bran, 5% corn flour, and a water content of 64% to 66%.

[0036] 3) 800 heterozygotes were obtained by conventional hybridization methods.

[0037] 4) Cultivation and screenin...

Embodiment 2

[0040] Embodiment 2 bacterial age test

[0041] In this example, the culture cycle (that is, the age of the mushroom, the same below) and the cultivation cycle are compared between the new strain Finc-W-62 of the pure white mushroom of the present invention and the existing pure white mushroom of H-W, which has good quality and is the most widely planted. , to illustrate the advantages and characteristics of the new pure white mushroom strain Finc-W-62 of the present invention.

[0042] The cultivar medium used in this example is: 25% corn cob, 23% miscellaneous sawdust, 20% soybean hulls, 12% rice bran, 15% bran, 5% corn flour, and the water content is 64%-66%.

[0043] Table 1 Bacteria age test

[0044]

[0045]Taking H-W as the control, set 7 bacterial ages from 70d (that is, days, the same below) to 100d for the culture period, and each increment of 5d is a bacterial age, and each bacterial age is 80 bottles. Cultivation and cultivation adopt conventional shimeji mush...

Embodiment 3

[0047] Embodiment 3 Parachute opening test

[0048] In Example 2, 10 bottles of Finc-W-62 and H-W at the 85th age in Example 2 were used as test objects, and the umbrella opening situation was recorded every day. Please refer to the results Figure 2-A , Figure 2-B , Figure 2-C And table 1~2, as can be seen from table 1, the optimal cultivation cycle of Finc-W-62 is 21d, the optimal cultivation cycle of H-W is 23d, when respectively in described optimal cultivation cycle, Finc-W-62 and The diameter of the cap of H-W is generally 1-2cm. Finc-W-62 did not open the umbrella after 5 days of continuous cultivation after the best harvest period, while H-W continued to cultivate for 1 or 2 days after the best harvest period before opening the umbrella. When harvesting, the optimal cultivation period of the two strains of Finc-W-62 and H-W is advanced 3 days, and both of them do not open umbrellas, that is, if Figure 2-A The left of the two mushroom caps shown is the 18th day ...

Abstract

The invention provides a pure white new hypsizigus marmoreus bacterial strain Finc-W-62, and the preservation number of the bacterial strain is CCTCC NO: M 2012375. The culture and cultivation periods of Finc-W-62 are short, the production cost is low, pileus is not easy to open, tumor stropharia rugosannulata ratio is low, the appearance quality is improved and sporophore shelf life is long.

Description

【Technical field】 [0001] The invention relates to the technical field of edible fungi, more precisely, it relates to a new pure white mushroom strain. 【Background technique】 [0002] True Ji mushroom (Latin name Hypsizygus marmoreus), belongs to Basidiomycotina, Laminomycetes, Agaricaceae, White Mushrooms, and Amygium genus. Because it has a unique crab flavor, it is also called crab-flavored mushroom. . The initial artificial cultivation began in Japan around 1978. It is delicious, crisp and tender, and rich in nutrition. The product is also full of fragrance. True jiji mushroom is rich in vitamins and 17 kinds of amino acids, and the β-glucan extracted from the fruiting body has high anti-tumor activity. It is a low-calorie, low-fat health food. [0003] As we all know, strains play a vital role in the factory cultivation of edible fungi. At present, there are two types of jiji mushrooms: brown and pure white. The pure white jiji mushroom is also called "white jade mus...
