Occurrence of cassava mosaic begomoviruses in national cassava germplasm preserved in two agro‐ecological zones of Ivory Coast

Plant Pathology, Volume 72, Issue 6, Page 1011-1021, August 2023., 2023
Cassava mosaic disease is significantly affecting cassava production in Ivory Coast. To reduce the impact of the disease, we assessed national germplasm to identify viruses and resistant accessions. Abstract Cassava production in Ivory Coast is hampered by cassava mosaic disease (CMD), which is caused by several begomovirus species. To increase cassava

Genetic parameters of drought tolerance for agromorphological traits in eggplant, wild relatives, and interspecific hybrids

Crop Science, Volume 61, Issue 1, Page 55-68, January/February 2021., 2021
Abstract Crop wild relatives (CWRs) have barely been used in eggplant (Solanum melongena) breeding. However, introgression breeding may help in coping with the challenges posed by climate change. During the rainy and dry seasons, we evaluated nine accessions of eggplant, nine accessions of seven related species (of which six are CWRs and one is a ...

Characterization of virus species associated with sweetpotato virus diseases in Burkina Faso

Plant Pathology, Volume 69, Issue 6, Page 1003-1017, August 2020., 2020
We investigated the viral disease threatening sweetpotato production in Burkina Faso. SPFMV, SPLCV and SPCSV were found; these viruses can occur together with severe symptoms. Abstract Sweetpotato (Ipomoea batatas) production in sub‐Saharan Africa is severely affected by viral diseases caused by several interacting viruses, including sweet potato ...
