Abstract:
... Twenty-two improved and local cassava genotypes were evaluated for their bacterial blight symptom types in reaction to infection by Xanthomonas axonopodis pv. manihotis under field conditions in the forest, forest savanna transition and wet savanna zones of Togo. High genotype x environment interactions in development of each symptom type were observed. Combining data on environments and genotypes ...

Abstract:
... It is widely recognized that conventional plant breeding has been more beneficial to farmers in high-potential environments or those who can profitably modify their environment to suit new cultivars, than to the poorest farmers who cannot afford to modify their environment through the application of additional inputs and cannot risk the replacement of their traditional, well known and reliable var ...

Abstract:
... The improvement of cotton fiber quality has become more important because of changes in spinning technology. Stable quantitative trait loci (QTLs) for fiber quality will enable molecular marker-assisted selection to improve fiber quality of future cotton cultivars. A simple sequence repeat (SSR) genetic linkage map consisting of 156 loci covering 1,024.4 cM was constructed using a series of recomb ...

Abstract:
... Cowpea, an important subsistence pulse crop in the tropics and subtropics is susceptible to several insect pests that seriously limit its yield potential. Pubescence (hairiness) on the parts of some of its wild relatives has been reported to reduce the damage caused by some of the insect pests. A generation mean analysis was conducted between a cowpea variety IT82D-716 and two accessions of Vigna ...

This paper considers the process of Participatory Varietal Selection (PVS) and presents approaches and ideas based on PVS activities conducted on upland rice throughout Ghana between 1997 and 2003. In particular the role of informal seed systems in PVS is investigated and implications for PVS design are identified. PVS programmes were conducted in two main agroecological zones, Forest and Savannah ...
