摘要
The establishment and development of artificial seed technology is to quickly reproduce excellent varieties or hybrids,which can be applied to hybrid generation seeds produced by the three-two line method.For some varieties that are difficult to propagate with seeds or plant species with unstable genetic traits and poor fertility,artificial seed technology can also be used for mass reproduction.In particular,some new plants created through genetic engineering,such as somatic hybrids or transgenic plants,can be propagated or maintained by artificial seed technology.In addition,artificial seed technology can be used for the maintenance and rapid propagation of virus-free seedlings.Compared with ordinary test tube seedlings,artificial seeds have low cost,convenient transportation,and to a certain extent reduce vitrified seedlings.In particular,the production of artificial seeds does not occupy a large amount of soil.It can be produced all year round.Therefore,the research on artificial seeds has developed rapidly in the world.
