Plant regeneration from immature embryos of peanut.
Plant regeneration from immature embryos of peanut (Arachis hypogaea L.) can be accomplished through somatic embryogenesis. The highest frequency of somatic embryo formation occurred on B5 medium plus 0.5-1.0 mg/l picloram. Shoots and plants developed from the somatic embryos only after extended culture on basal medium. Shoots were excised from thick embryonic roots and rerooted on Murashige and Skoog medium containing half the normal concentration of inorganic salts. This technique should be useful for the production of interspecific hybrid plants from immatureArachis embryos.
