The effects of processing and harvesting time on the physical and sensory characteristics of micronutrient biofortified yellow maize varieties have been investigated using standard procedures. Freshly harvested eight biofortified yellow maize hybrids and eight open pollinated varieties (OPV) with...

Ear-rot-causing fungi, including Aspergillus and Fusarium spp., are common in maize in West and Central Africa. These fungi contaminate maize with mycotoxins that pose serious potential health hazards to humans in these areas. A collaborative germplasm screening project was initiated between the ...

The history of bean breeding in Uganda from 1960-90 is reviewed, covering production constraints, germplasm collections, introductions, and cultivar release. Note is made of the restructuring of the breeding programme in 1989 and the resulting large increase in breeding material handled. Yield re...

Se revisa la historia del mejoramiento de frijol en Uganda de 1960-90, incluyendo los limitantes de la produccion, recolecciones de germoplasma, introducciones y liberacion de cv. Se destaca la reestructuracion del programa de mejoramiento en 1989 que dio como resultado un incremento considerable...

Maize production is constrained by Striga hermonthica in Mali leading to high yield losses. Breeding resistant hybrid maize is a promising alternative for increasing farmers’ income. The objective of this study was to evaluate the response of test crosses to Striga hermonthica and identify high y...

Breeding programs involve large investments of time and money, but can pay very large returns on investment in the form of improved varieties that benefit farmers, societies and the environment. International breeding efforts involving multiple partners and targeting regionally important constrai...

Despite considerable efforts of Musa improvement programmes, banana and plantain production still depends upon a limited number of landraces selected by man from the natural germplasm. Inability to replace land-races by cultivars obtained through cross-breeding creates the increased risk of epide...

Secondary triploids were produced by crossing primary tetraploids with selected diploid partners and the parthenocarpic banana (Galeo). Comparisons between secondary tetraploids and secondary triploids showed that the secondary tetraploids generally had lower yields than secondary triploids. The ...

Restriction Fragment Length Polymorphisms (RFLPs) were used to study the genetic diversity within and between accessions of 'wild' and cultivated B. rapa. Two of the wild accessions were likely to be escapes from cultivation because of their geographical origins (Argentina and California). The na...

During the last decade, genomics research has generated new insights into potato genetics and made possible new strategies for varietal improvement. The most commonly grown and eaten potato is an autotetraploid, highly heterozygote crop suffering from rapid inbreeding depression. The genetic impr...

Recurrent selection under artificial S. hermonthica infestation has significantly reduced the number of emerged Striga plants and increased grain yield under Striga infestation in broad-based populations. These populations have been sources of varieties and inbred lines with consistently high lev...
