Cassava (manioc, yuca, or mandioca; Manihot esculenta Crantz, Euphorbiaceae) is an important cash crop and food crop of resource-limited farmers in Africa, Asia, and Latin America and the Caribbean. The storage roots are utilised either fresh, as in the case of sweet cultivars low in cyanogenic g...

Phenotyping cassava for adaptation to drought
Early-maturing provitamin A (PVA) quality protein maize (QPM) hybrids with combined drought and low soil nitrogen (low-N) tolerance are needed to address malnutrition and food security problems in sub-Saharan Africa (SSA). The current study's objectives were to (i) examine combining ability of se...

Improved varieties have agronomic advantages over local varieties,but not much attention has been given to understand the nutritional content of the improved cowpea varieties released in Swaziland. This study investigated the physical and nutritional properties of improved cowpea varieties releas...

We evaluated the yields of Oryza sativa L. ‘Nipponbare’ rice lines expressing a gene encoding an A20/AN1 domain stress-associated protein, AlSAP, from the halophyte grass Aeluropus littoralis under the control of different promoters. Three independent field trials were conducted, with drought imp...

Drought stress has often caused significant decreases in crop production which could be associated with global warming. Enhancing drought tolerance without a grain yield penalty has been a great challenge in crop improvement. Here, we report the Arabidopsis thaliana galactinol synthase 2 gene (At...
The purpose is to evaluate forage germplasm with the potential use in the region, for which the establishment of genotype-environment tests (Multilocaciones) of some advanced and no evaluated forages materials in the region was performed in this case Cenchrus ciliaris and Chloris gayana, Under th...

Water shortage is an important limiting abiotic factor in agriculture, and the problem is expected to increase with climate change causing more frequent and more severe droughts in many areas. Banana needs vast amounts of water for optimal production. In commercial Cavendish export production sys...
Low maize yields and the impacts of climate change on maize production highlight the need to improve yields in eastern and southern Africa. Climate projections suggest higher temperatures within drought-prone areas. Research in model species suggests that tolerance to combined drought and heat st...

The effects of 0.2% aqueous solution of colchicine on the survival rate and morphological features of five accessions of Dioscorea alata were investigated. Sprouting buds of two month old plants were treated with 0.2% colchicine and their performances were monitored until maturity. Survival of bu...
