In vitro regeneration of castor (Ricinus communis L.)

Abstract

Standardization of a reliable regeneration protocol is important in castor to develop transgenics conferring resistance to biotic and abiotic stresses. An attempt has been made to develop an in vitro regeneration protocol using the hypocotyl explants derived from seedlings obtained from de-coated seeds. Out of 60 different hormonal combinations tried, three combinations showed better shoot induction and the rooting was better with IBA 1.0 mg/L
