A simple protocol was established for high frequency direct shoot regeneration of cowpea [Vigna unguiculata (L.) cv. EPACE-1]. Bud proliferation occurred at the cotyledonary nodes of cowpea seedlings three weeks after culture on a medium containing Murashige and Skoog salts (1962) and B5 vitamins (Gamborg et al. 1968) supplemented with TDZ. A 10
mol/L TDZ pre-treatment, shoot tip removal and excision of longitudinal thin cell layers (TCL) at the level of the cotyledonary nodes with subsequent culture on a MSB5 medium supplemented with 1
mol/L IBA and 1
mol/L TDZ were the optimal conditions for maximum bud proliferation. Up to 32.5 regenerated shoot buds were produced per TCL. The regenerated plants (R0) were true-to-type and successfully transferred to soil.
