Development of a hot pepper root rot and wilt disease management strategy through genetic resistance, chemical application and proper choice of rotational crops

This study seeks to contribute to increased productivity of hot pepper (Capsicum chinense) by incorporating an integrated pest management (IPM) package for root rot/wilt disease (Phytophthora capsici). Pathogen host diversity will be determined to guide the use of crop rotation in managing the disease. Oomycete fungicides will be screened for effectiveness in managing P. capsici. Additionally, resistance introgression will be carried out with resistant donors. The contribution of the Phyto 5.2 QTL disease resistance will also be determined in order to assess its usability in resistance breeding. The study will be carried out in collaboration with pepper farmers in Kasese, Uganda.
Cette étude cherche à contribuer à la plus grande productivité du poivre âcre (Capsicum chinense) en incorporant un ensemble intégré de gestion du parasite (IPM) pour la putréfaction de la racine/la maladie de desséchement (Phytophthora capsici). La diversité d’organisme infecté par le microbe pathogène sera déterminée pour guider l’utilisation de la rotation de cultures dans le contrôle de la maladie. Des fongicides d’Oomycètes seront examinés pour l’efficacité dans le contrôle de P. capsici. En plus, l’incorporation des gênes de résistance sera effectuée avec les donneurs résistants. La contribution de la résistance à la maladie Phyto 5.2 QTL sera également déterminée afin d’évaluer sa rentabilité dans la multiplication de résistance. L’étude sera effectuée en collaboration avec des agriculteurs de poivre à Kasese, Ouganda.

"The 2010 RUFORUM Biennial Conference was the second 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. This record contains an extended abstract accepted under the theme diseases".
