白色平菇因其洁白、肉厚,畅销于国内外市场。为了填补我省无白色平菇品种的空白,我们开展了白色平菇品种选育研究。1991年我们从栽培的灰黑色平菇品种中获得一株白色变异菌株,命名为川白1号,与其它白色平菇菌株和灰黑色高产平菇品种进行评比试验,现报告如下: 1 材料与方法 1.1 菌种来源 川白1号自选;特白平菇引自江苏省农科院蔬菜所;青平1号本中心保藏菌株;杂交17本中心保藏菌株。除杂交17为灰黑色菌株外,其余的均为白色菌株。 1.2 拮抗试验 将三个白色平菇菌株接种在平皿PDA培养基上,在25℃恒温箱内培养,观察三个菌株的菌丝相互接触后的表现。 1.3 品比试验方法 栽培料配方为棉子壳98％,蔗糖、石膏各1％,含水量68％。用22×38cm规格的聚乙烯塑料袋,每袋装干料重520g,每个菌株20袋。常
White mushroom because of its white, fleshy, best-selling in domestic and foreign markets. In order to fill the gaps in our province without white Pleurotus ostreatus species, we conducted a white Pleurotus ostreatus breeding research. In 1991, we obtained a white mutant strain from cultivated Gray-black Pleurotus ostreatus, named Chuanbai No.1, and compared with other white Pleurotus ostreatus strains and gray-black high-yield Pleurotus ostreatus varieties. The report is as follows: 1 Materials and Method 1.1 Chuanbai No. 1 strain source selection; special white mushrooms cited from the Jiangsu Provincial Academy of Agricultural Sciences vegetable; Qingping No. 1 Center for the preservation of strains; hybrid 17 strains of the Center. In addition to hybrid 17 gray-black strains, the rest are white strains. 1.2 Antagonism Test Three white Pleurotus ostreatus strains were inoculated on a plate PDA medium and cultured in a 25 ° C incubator to observe the appearance of the mycelium of the three strains after being in contact with each other. 1.3 The ratio of test methods Cultivation recipe for cotton seed hull 98%, sucrose, gypsum 1%, 68% water content. With 22 × 38cm polyethylene plastic bags specifications, each bag of dry weight 520g, 20 bags per strain. often
