Somatic embryogenesis in polyembryonic Secale cereale L.

Summary The progeny of polyembryonic Secale cereale L., was used to study the in vitro response of the immature embryos. The formation of embryogenic calli was very high, and this response and its distribution was statistically different to that shown by the normal regenerated plants and the original population. This behaviour seems to be related to a genetic condition which favours the presence of supernumerary embryos, in vivo as well as in vitro.
