食用菌育种目前采用的手段也是其他生物常用的三种,即自然选育、诱变育种和杂交育种,从现有发展水平来看,具有了初步基础,下面就分三个方面作一简要叙述。一、自然选育自然选育是利用自然变异,选取所需的有益变异,这虽然是古老的方法,但在食用菌野生资源未充分开发和利用的时候,自然选育是有着重大潜力的,因此,自然选育是 At present, the means of edible fungus breeding is also commonly used by other organisms, namely, natural breeding, mutagenesis breeding and crossbreeding. From the current development level, it has a preliminary foundation. The following is a brief description of the three aspects . First, the natural breeding Natural selection is the use of natural variation, select the desired variation, although this is the ancient method, but the edible fungus wild resources are not fully developed and utilized when natural breeding has great potential, Therefore, natural selection is
