Strengthening Breeding for Resistance to Turcicum Leaf Blight in Sorghum: Mapping of Resistance Quantitative Trait Loci

Abstract: 
Sorghum cultivars grown in East and Central Africa are susceptiple to various foliar diseases, of which turcicum leaf blight, caused by Exerohlium turcicum, causes severe damage. The best way to control foliar diseases is by breeding resistant sorghum genotypes This can be best done with the help of marker assisted breeding technology and also by deploying multiple genes that confer either qualitative or quantitative resistance. In this research project, we intend to identify quantitative trait loci and molecular markers tightly linked with resistance to Exerohilum turcicum.
Les cultivars de sorgho cultivées en Afrique orientale et centrale sont susceptibles à diverses maladies foliaires, dont la rouille des feuilles turcicum, causée par l’Exerohlium turcicum, provoque de graves dommages. La meilleure façon de lutter contre les maladies foliaires est la reproduction de génotypes de sorgho résistant avec l’aide de la reproduction assistée par les marqueurs et aussi par le déploiement de plusieurs gènes qui confèrent une résistance qualitative ou quantitative. Dans ce projet de recherche, nous avons l’intention d’identifier les traits quantitatives de loci et les marqueurs moléculaires étroitement liés à la résistance aux Exerohilum turcicum.

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 the theme of Crop Improvement
