Genetic characterization and population structure of maize populations using SSR markers
Annals of Agricultural Sciences, 2019 Maize is a major staple food in sub-Saharan Africa. However, due to the threats posed by biotic and abiotic constraints to its production, it is a prerequisite to conserve germplasm with diverse genetic background and to seek for favourable genotypes ...

Tree size and herbivory determine below-canopy grass quality and species composition in savannahs [PDF]
, 2009 Large single-standing trees are rapidly declining in savannahs, ecosystems supporting a high diversity of large herbivorous mammals. Savannah trees are important as they support both a unique flora and fauna.

Generation mean analysis of the key earliness related traits in cowpea (Vigna unguiculata (L.) Walp)
Scientific African, 2022 The nature of gene action controlling agronomic traits enables plant breeders to execute a successful crop improvement programme. To elucidate the type of gene action governing the key earliness related traits in cowpea, seven populations of the six ...
