An efficient and reproducible micropropagation protocol of Solanecio biafrae (Oliv. & Hiern) C. Jeffrey has been developed from nodal stem segments. Shoot development was obtained on Murashige and Skoog (MS) medium supplemented with benzylaminopurine (BAP) alone and in combination with zeatin and 1-naphthaleneacetic acid (NAA). Elongated shoots were rooted in the presence of zeatin or 3-indole-butyric acid (IBA) alone or in combinations. The highest number of explants forming shoots (100%) as well as the highest number of shoots per explant (3.4) and the longest shoots (22 mm) were recorded on medium containing 4.0 mg·dm−3 BAP, 2.0 mg·dm−3 NAA, and 1.0 mg·dm−3 zeatin. About 76% of shoots formed roots on half-strength MS medium free of plant growth regulators. The best root formation (approximately 88%) was recorded on the medium containing 1.0-1.5 mg·dm−3 IBA. The micropropagated shoots with well-developed roots were efficiently acclimatized under greenhouse conditions. The random amplified polymorphic DNA (RAPD) and intersimple sequence repeat (ISSR) amplification products were monomorphic in micropropagated plants and similar to those of mother plant showing their genetic uniformity. This is the first report of micropropagation of S. biafrae, which will facilitate in vitro mass propagation, conservation, and germplasm exchange of this endangered African vegetable
