Aluminium (Al) toxicity and drought are two major factors limiting common bean (Phaseolus vulgaris) production in the tropics. Short-term effects of Al toxicity and drought stress on root growth in acid, Al-toxic soil were studied, with special emphasis on Al–drought interaction in the root apex....
Maize is a major staple food crop in southern Africa and stress tolerant improved varieties have the potential to increase productivity, enhance livelihoods and reduce food insecurity. This study uses big data in refining the geospatial targeting of new drought-tolerant (DT) maize varieties in Ma...
Knowledge of the heterotic responses of elite adapted and exotic maize inbred lines can facilitate their utilization for population improvement and hybrid development. In the present study, a line x tester mating design was used to determine the combining ability of 20 elite drought-tolerant maiz...
Availability of extra-early maize cultivars has facilitated the expansion of maize production into savannas of West and Central Africa (WCA). Fifty-six extra-early maize cultivars of three breeding eras;1995 to 2000, 2001 to 2006, and 2007 to 2012 were evaluated for 2 yr under 24 multiple-stress ...
Genotype × environment interactions complicate selection of superior genotypes for narrow and wide adaptation. Eighteen tropically-adapted maize cultivars were evaluated at six locations in Nigeria for 2 yr to (i) identify superior and stable cultivars across environments and (ii) assess relation...
The key aim of the ‘Nutritious Orange-Fleshed-Sweetpotato for Niassa, Mozambique' project, which began in November 2012, is to improve vitamin A and energy intake for at least 20,000 rural households with women and young children using orange-fleshed sweetpotato focused, food-based approaches tha...
The Viable Sweetpotato Technology in Africa (VISTA) is a three-year project which began in October 2014 and aims to contribute to improved nutrition, food security and incomes among smallholder farming families through increased production and better utilization of nutritious OFSP varieties, espe...
Drought tolerance combined with resistance to black sigatoka (BS) disease are two desirable traits for plantains in some parts of the tropics. Field evaluation of leaf stomatal conductance, single leaf transpiration rate, photochemical efficiency, and role of stomata in BS resistance, was done fo...
