African origin of Bradyrhizobium populations nodulating Bambara groundnut (Vigna subterranea L. Verdc) in Ghanaian and South African soils
The results showed that a cropping history and physico-chemical environment of soils increased bradyrhizobial diversity in Ghana and South Africa and the grouping of isolates according to symbiotic gene (nifH and nodD) phylogenies revealed inter- and intra-specific symbiotic plasmid transfer and different evolutionary history.

Characterization of Groundnut (Arachis hypogaea L.) Test Locations Using Representative Testing Environments With Farmer-Preferred Traits
This study studied the differential rankings of 36 groundnut genotypes under varying environmental conditions, finding that the locations represent one complex mega-environment, justifying the need to test new technologies, including genotypes in all of them before they can be approved for adoption nationally.

Phylogeny and distribution of Bradyrhizobium symbionts nodulating cowpea (Vigna unguiculata L. Walp) and their association with the physicochemical properties of acidic African soils
This study collected cowpea-nodules from acidic soils in Ghana and South Africa, and nodule DNA isolates were characterized using 16S–23S rRNA-RFLP, phylogenetic analysis of housekeeping and symbiotic genes, and bradyrhizobial community structure through canonical correspondence analysis (CCA).

Genetics of Stay-Green Trait and Its Association with Leaf Spot Tolerance and Pod Yield in Groundnut
Stay-green trait in groundnut was detected to be under the control of a single recessive gene and hence may be used to select for ELS and LLS resistance. Expand
Enhancing Access to Quality Seed of Improved Groundnut Varieties Through Multi-Stakeholder Platforms in Northern Ghana
One of the main constraints to groundnut production has been the use of low yielding varieties, susceptible to biotic and abiotic stresses. Multi-stakeholder platforms (MSPs) have been used byExpand
Black Seedcoat Pigmentation Is a Marker for Enhanced Nodulation and N2 Fixation in Bambara Groundnut (Vigna Subterranea L. Verdc.) Landraces
Field studies on the effect of differing seedcoat colour on plant growth and symbiotic performance of three Bambara groundnut landraces using the 15N natural abundance technique and ureide analysisExpand
Genetic Control of Fruit Yield and Its Component Characters in Hot Pepper {Capsicum Annuum L.)
Analysis of variance of the mean performances of the Fis and their parents revealed significant differences among the genotypes implying the presence of variability, and ‘BEK' was identified as the best combiner for fruit number/plant and earliness. Expand
