目前,国内外都已开展以单孢分离杂交为主的食用菌育种工作。用此法得到的新品种,究竟要栽培几代才能稳定性状,进行大面积推广?有两种看法:一种认为应象小麦、水稻育种那样,通过杂交初选出的新品种,需经十代左右的栽培,才能稳定性状;另一种则认为,只需2～3代的栽培观察,就能确定新品种的性状和栽培条件而应用于生产。
At present, the breeding of edible fungi which is mainly composed of single spore separation and hybridization has been carried out at home and abroad. The new varieties obtained by this method, how many generations can be cultivated to stabilize the trait, the promotion of a large area? There are two views: one that should be like wheat, rice breeding, through the hybrid primary selection of new varieties, subject to ten On the other hand, it takes only 2 ~ 3 generations of cultivation observation to determine the traits and cultivation conditions of the new varieties and apply them to the production.
