Solanum Taxonomy - Morning Manoko, M.L.K. [1], van den Berg, R.G. [2], Feron, R.M.C. [1], van der Weerden, G.M. [1], Mariani, C. [1]. Taxonomy of Solanum section Solanum in Africa. THE usefulness of section Solanum species to the daily livelihood of people in Africa cannot be overestimated. They form one of the largest sources of leafy vegetables, they are rich in minerals, proteins, vitamins and energy, they are used as medicinal plants and as fodder, and they provide a source of income for women in urban areas. However, the taxonomy of this group is not completely elucidated, especially with respect to the African taxa, namely, S. americanum Mill., S. chenopodioides Lam., S. physalifolium Rusby, S. tarderemotum Bitt., S. florulentum Bitt., S. grossidentatum A. Rich., S. hirsutum Dunal, S. pseudospinosum C. H. Wright, S. retroflexum Dunal, S. nigrum L., S. scabrum Mill. and S. opacum A. Br. and Bouché. This study was designed to evaluate the contribution of AFLP markers to improve the classification of these species. AFLP datasets generated from 208 accessions from different geographical areas were analyzed using NJ and MP methods in PAUP. In some instances our study supported the current classification, but also in some cases contradicted the existing species delimitations, especially in the diploid and tetraploid species. The AFLP data were supplemented with morphological observations and data on crossability to evaluate hypotheses about hybridisation and introgressive hybridization, stressing. the need to use a combination of different sources of taxonomic information to resolve the taxonomic issues in section Solanum.
