芽变是植物体细胞突变的一种,即突变发生在芽的分生组织细胞中,当芽萌发长成枝条,并在性状表现上与原来不同。与常规杂交育种相比,芽变育种周期短,方法简单易于掌握,一些性状优良的栽培品种,一旦发生可利用的性状变异,马上可以推广应用。 Budding is a kind of plant somatic mutation, that is, the mutation occurs in the shoot meristem cells. When the buds grow into branches, they behave differently from the original ones. Compared with conventional crossbreeding, bud mutation breeding cycle is short, the method is simple and easy to master, some cultivars with good traits, in the event of available trait variation, can be popularized and applied.
