当前，对金针菇产、质量要求越来越高，不仅产量要高，而且要求菇形好，柄白，硬挺，耐贮运。为此，我们开展了金针菇的杂交育种试验，现将选育出的一株较优良的杂交菌株川金 2号的特性介绍如下：1　材料和方法1 1　供试亲株　Ｆｖ12 菌株来自本单位，为生产上大面积栽培菌株 At present, the mushroom production, quality requirements are getting higher and higher, not only yield is high, but also requires mushroom shape, handle white, stiff, resistant to storage and transportation. To this end, we carried out the flammulina crossbreeding test, now breeding a more excellent hybrid strain Chuanjin 2 characteristics are as follows: 1 Materials and methods 1 1 test progeny Fv12 strains from the unit, For the production of large-scale cultivation of strains
