Application of tissue culture to tuber crops at IITA

1985

Ng, S.Y. | Hahn, S.K.

The international germplasm exchange for tuber crops is hampered by the risks of introducing, through vegetative materials, diseases and pests to noninfected areas. Since tuber crops are vegetatively propagated, their conservation as germplasm is also a problem. At IITA, we have used meristem culture to eliminate disease in tuber crops: disease-free plants can be distributed in vitro to requesting national programs. Disease-free sweet potato has been distributed to more than 40 countries throughout the world, and cassava to over 30 countries in Africa. Minimal growth storage is used at IITA to conserve germplasm of sweet potato and yams. Over 600 clones of sweet potato germplasm are held in vitro. Arrangements for in vitro tuber crops germplasm exchange are described
