The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under Integrated Crop Management
Unraveling the Vector Transmission Biology of the Ipomovirus Sweet Potato Mild Mottle Virus (Potyviridae) in Sweetpotato (Lam.)
Abstract:
This study undertakes to unravel vector transmission biology
of Sweet potato mild mottle virus (SPMMV), a type member
of the genus Ipomovirus in the family Potyviridae. This study
will be conducted in four selected districts of Uganda for two
sweetpotato growing seasons of 2012 and 2013. The districts
include Masaka and Mpigi (around Lake Victoria basin in
Central region); and Mbale and Soroti (Eastern region).
Sweetpotato is the second most important root crop in East
Africa, but production there is greatly constrained by viruses
including SPMMV, a critical component of the devastating
sweet potato virus disease (SPVD) complex. While the vectors
disseminating other common viruses of sweetpotato in East
Africa are well known, the vector transmitting SPMMV has
remained cryptic. Consequently, the epidemiological relationship
between incidence of SPMMV and its potential vectors in the
fields is unknown. The vector transmitting SPMMV in
sweetpotato and the SPMMV-vector epidemiological relations
under field conditions will be determined. Farmer awareness
of SPVD complex effects of sweetpotato yield will be enhanced
through field activities involving farmers.
Cette étude vise à dénouer la biologie de la transmission des
vecteurs du virus de tache légère de la patate douce (SPMMV),
un membre type du genre Ipomovirus dans la famille
Potyviridae. Cette étude sera menée dans quatre districts
sélectionnés de l’Ouganda pour deux saisons de croissance de
la patate douce de 2012 et 2013. Les districts comprennent
Masaka et Mpigi (aux environs du bassin du lac Victoria dansla région centrale) ainsi que Mbale et Soroti (dans la région de
l’Est). La patate douce est la deuxième plus importante culture
des racines comestibles en Afrique Orientale, mais la production
est fortement contrainte par des virus, y compris SPMMV, un
constituant essentiel du complexe des maladies dévastatrices
causées par le virus de la patate douce (SPVD). Alors que les
vecteurs de diffusion d’autres virus communs de la patate douce
en Afrique de l’Est sont bien connus, le vecteur de transmission
de SPMMV est resté énigmatique. Par conséquent, la relation
épidémiologique entre l’incidence de SPMMV et ses vecteurs
potentiels sur terrain est inconnue. Le vecteur de transmission
de SPMMV dans la patate douce et les relations
épidémiologiques SPMMV-vecteur sur le terrain seront
déterminés. La sensibilisation des agriculteurs sur les effets
complexes de SPVD sur le rendement de la patate douce sera
augmentée.
