description Buckwheat (<i>Fagopyrum esculentum</i>, Family Polygonaceae) is an annual pseudo-cereal crop with healing benefits. However, the genetic improvement of common buckwheat has achieved only limited success, mainly due to buckwheat&#8217;s dimorphic flowers and heteromorphic self-incompatibility. Here, we develop a useful protocol for indirect somatic embryogenesis and subsequent plant regeneration from hypocotyl explants of <i>F. esculentum</i>. Firstly, the initial calli of hypocotyl explants were induced on Murashige and Skoog (MS) basal medium containing 2.0 mgL<sup>&#8722;1</sup> 2,4-D and 1.5 mgL<sup>&#8722;1</sup> 6-BA for 30 days culture, and then the yellowish white friable embryogenic calli were developed when the initial calli were transferred to fresh MS basal medium supplemented with 1.0 mgL<sup>&#8722;1</sup> 6-BA and 0.5 mgL<sup>&#8722;1</sup> thidiazuron (TDZ)two to three times subculture at 40&#8722;60 days intervals. Subsequently, the somatic embryos were able to germinate from embryogenic callus sub-cultured on MS basal medium containing 1.0 mgL<sup>&#8722;1</sup> 6-BA and 0.5 mgL<sup>&#8722;1</sup> TDZ with 15% potato puree for 20 days subculture. Finally, maximum mean percentage (75.75%) of somatic embryo-derived plants were obtained when the mature somatic embryos were transferred to MS basal medium without growth regulators for 40 days culture. Our result provides a useful protocol for plant regeneration and SE from hypocotyl explants of <i>F. esculentum</i>.
