Research Progress of Plant Germplasm in Vitro Conservation

There are three forms to conserve plant germplasm: in situ conservation, ex situ conservation and in vitro conservation, of which the in virto conservation is the most effective and safel way. The in vitro conservation include three ways, that is genebank, cryopreservation and in virto culture. This paper summarized the theory and technological characteristics, the utilities of plant germplasm conservation, and the research focus and development trends of the three ways of in vitro conservation.
