Morphovariability and agronomic characteristics of soybean accessions from the Democratic Republic of Congo (DR-Congo) gene pool
Soybean [(Glycine max (L.) Merr.] is the most important grain legumes in the world in terms of total production. But only a fraction of its accessions has been characterizedbased on origin, morphometric traits, agronomic performance and seed composition. This crop is now cultivated to a very limited extent in twenty one sub-Saharan African countries. The main objective of the present study is to...

Performance of drought tolerant three-way and top cross maize hybrids in Sudan Savanna of North Eastern Nigeria
Field experiments were conducted during the 2008 cropping season in two locations in Lokodisa, Gwoza Local Government Area and Sabongari in Damboa Local Government Area both in Borno State Nigeria. These two locations are both located within the Sudan Savanna agro-ecology of north-eastern Nigeria and the soil of the area is clay loam and are well drained. The study was conducted in order to evaluate the performance of...

In vitro explants regeneration of the grape ‘Wink’ (Vitis vinifera L. ‘Wink’)
The effects of different hormones and their concentration combinations, different explant types, dark periods, on the regeneration of the grape ‘Wink’ was investigated using in vitro leaves, petioles, internodes and radicles. The results showed that of all the media prepared, the explants on following media produced the highest regeneration rate: 78.74±1.60% of the leave explants...

Assessment for drought adaptive and reproductive traits of field-planted upland rice genotypes in a derived savannah ecology
A field study was conducted in derived savannah ecology to evaluate sixteen upland rice genotypes comprising breeding lines, recent releases and established cultivars for the effect of different rainfall-seasons on genotypic trait expression and to identify those harbouring drought adaptive characters. Plantings were done in the early and late rain seasons of 2006 and 2007, respectively. Data were collected...

Floral biology of Bambara groundnut [Vigna subterranea (L.) Verdc]
Investigation on floral biology of twelve accessions of Bambara groundnut [Vigna subterranea (L.) Verdc] was carried out in the greenhouse of the School of Agriculture and Agricultural Technology, Federal University of Technology, Owerri, Nigeria, in a completely randomized design with three replications. Significant varietal differences (P<0.05) were observed among the accessions in all...
