在食用菌的杂交育种中,根据亲本细胞核和细胞质成分在后代中的组合和分配,可以分为对称杂交和非对称杂交两种方式。对称杂交主要指异宗结合食用菌的单孢杂交(或同宗结合食用菌的同核体杂交)和原生质体融合;非对称杂交则包括单双核杂交(布勒杂交)、失活原生质体融合和外源 DNA 导入等方式。
In the edible fungus hybrid breeding, according to the parental cell nucleus and cytoplasmic composition in the offspring of the combination and distribution, can be divided into symmetrical hybridization and asymmetric hybridization in two ways. Symmetrical hybridization mainly refers to heterotrophic combination of edible fungus single spore hybridization (or the same combination of edible fungi with the nuclear hybrid) and protoplast fusion; asymmetric hybridization, including single and double nuclear hybridization (Bulble hybridization), inactivated protoplast fusion and Foreign DNA introduction and other means.
