Two contrasting clones of cassava (Manihot esculenta) were reciprocally grafted to test the hypothesis that the yield of cassava is limited by the number of storage roots. Effects of the root sink on leaf gas exchange were also tested under field conditions using a portable infra-red gas analyzer...

Drought stress is one of the major abiotic factors limiting banana (Musa) production. Even mild-drought conditions are responsible for considerable yield losses. We performed large-scale transcriptome sequencing using Illumina technology on root tissue of three triploid genotypes representing wel...

The resistance of 9 bean cv. to isolates of Thanatephorus cucumeris collected from either leaves (Th-5) or roots (Rs-8) of infected plants was tested under controlled conditions in growth chambers (22-25 degrees Celsius, 80-100 percent RH and 12 h artificial light). Adequate concn. of inoculum of...

Alfalfa or lucerne (Medicago sativa L.) is an important forage legume grown extensively in the world. There have been relatively few investigations on the adaptation of alfalfa to soils found in suitable eco-zones in Africa. In the present investigations, twenty accessions were evaluated for tole...

Commercialization of sweetpotato vines is persistent if multipliers show evidence of superiority of their vines. This study aimed at evaluating the effects of net tunnel source and of pathogen tested planting material compared to “apparently” healthy vines on yield and health status at three defi...

Potato has underexploited potential to contribute to food security and income generation among Ugandan small-scale women and men farmers. This project focuses on building the skills of private sector early-generation seed producers and decentralized seed multipliers and improving current ware pot...
