我们知道,植物在繁殖过程中遵循着遗传与变异法则。花卉的育种过程,就是采用各种手段,促使花卉基因发生突变,打破遗传的稳定性,再从突变植株中选择具有优良性状的植株的过程。新品种的选育工作就是围绕这两方面进行的。具体说来,有以下几种方法: 野外寻找植物在野生时,总有着各种各样的变异,其中可能产生具有优良性状的植株,如果我们用心搜寻,就有可能获得新品种。如红枫、金边瑞香、红棍木等,都是前人用这种方法选出的。名贵的中国兰花,目前几乎全部采用这种方法选择新品种。
We know that plants follow the laws of genetics and mutation during reproduction. Flower breeding process, is to use a variety of means to promote mutations in flower genes, breaking the genetic stability, and then select from mutant plants with excellent traits of plants. Breeding of new varieties is carried out around these two aspects. Specifically, there are several ways to look for plants in the wild: There are always a variety of variations in the wild that may produce plants with excellent traits, and if we search, we will be able to obtain new varieties. Such as Hongfeng, Phnom Penh Ruixiang, red stick wood, etc., are predecessors in this way elected. Expensive Chinese orchids, almost all currently using this method to select a new variety.
