遗传力(heritability)是指亲代传递其遗传特性的能力,在杂交育种中,可以作为选择杂种后代的一个指标。杂种后代性状的表现型是亲本基因型和环境条件共同作用的结果,因此表现型方差包括由遗传作用引起的方差和由环境影响引起的方差,其中遗传方差占总方差的比值称为广义遗传力。根据数量性状估算出的广义遗传力在香菇和其它食用菌的杂交育种中具有重要的意义。我们以香菇单核原生质体再生菌丝为材
Heritability refers to the ability of parents to pass on their genetic traits and can be used as an indicator of the selection of hybrid offspring in crossbreeding. The phenotype of hybrid progeny traits is the result of the interaction between the genotype and environmental conditions of the parents. Therefore, the phenotypic variance includes the variance caused by the genetic effect and the variance caused by the environmental impact, and the ratio of the genetic variance to the total variance is called the generalized heritability . The generalized heritability estimated from quantitative traits is of great significance in the cross breeding of shiitake mushrooms and other edible mushrooms. We use mushroom mononuclear protoplast regeneration hypha for material
