在植物的杂交育种中,要使杂种后代中出现一个亲本的大部分性状,而只引入另一个亲本的一个或少数几个性状,是很困难的。但是近来出现了一些在植物上用照射花粉授粉,将单个基因或部分雄性核物质从一个植物转移到另一个植物(包括远缘植物)中去的报道。这是很吸引植物育种家的工作,因为这不仅可以加速植物育种过程,还可 In hybrid breeding of plants, it is difficult to introduce most of the traits of a parent in the offspring of the progeny, but only to one or a few traits of another parent. However, there have been recent reports of pollination of irradiated pollen on plants by transferring a single gene or a portion of male nuclear material from one plant to another, including the distant plant. This is a very attractive job for plant breeders because it not only speeds up plant breeding but also
