    • Sweetpotato is a major source of energy, minerals, and vitamins In West Africa, sweetpotato is gradually becoming an important crop because of its potential as a food and industrial crop, and can be produced in almost all the agro-ecological zones in the sub- region. Sweetpotato is relatively poor in essential amino acids with tryptophan, methionine, and Lysine being the most limiting and to a lesser extent isoleucine, theorine and leucine. An increase in these essential amino acids in the crop will be more beneficial.

    • Maruca-Resistant Cowpea Project Funded by Africa Agricultural Technology Foundation, (AATF), Nairobi, Kenya
    • Pod damage
    • IITA and NARS in West Africa dedicated over 30 years to cowpea research and development. Breeding for pest, disease and abiotic stresses Insect pests: Aphids, flower thrips, pod borers, pod -sucking bugs, bruchids.
    • Establishment of T0 plantlets in soil Successful Genetic transformation - stable
    • Single Copy inserts: Southern blotting Integrity of inserts: DNA sequencing Cry1Ab gene transmits to next generation and segregates in Bt cowpeas Bt protein is expressed in green tissues (pods, young seeds), pollen etc

    • Ghana has signed the Cartagena Protocol on Biosafety The national biosafety framework and regulations have been developed. Environment safety : testing of Bt cowpea must be conducted according to international and national regulations Ensures food and feed safety
    • Application Permit Planting Harvest/Termination Completion Technical Review Regulatory Decision Legal Authorization With Terms & Conditions Regulatory Inspections Current Season Post-Harvest Period
    • Aim to: Prevent dissemination of new genes into the environment (i.e., prevent pollen flow) Prevent the persistence in the environment of the experimental biotech plants and progeny (i.e., contain seed and planting material) Prevent introduction of the experimental material into livestock feed or human food pathways
