菌种生产程序,分为母种、原种、栽培种三个层次,也就是通常所说的一级、二级、三级菌种。其中母种分离选育技术性强,要求精细;而原种和栽培种制作比较简单。有经验的菇农,只要掌握生产程序和制种技艺,就可以自行制种,逐步发展成制种专业户。 一、母种分离选育 主要由人工选择、诱变育种和杂交育种、原生质融 Strain production program, divided into mother species, original species, three kinds of cultivated species, which is commonly referred to as a, two, three species. Among them, the breeding and breeding of the mother species is strong and requires fineness. However, the original species and the cultivated species are relatively simple to produce. Experienced mushroom farmers, as long as the production process control and seed production techniques, we can make their own seeds, and gradually developed into specialized households. First, separation and breeding of mother species mainly by artificial selection, mutation breeding and cross breeding, protoplast fusion
