Relationship between grain yield and Fusarium head blight in soft red winter wheat as influenced by cultivar resistance

Abstract: 
Fusarium Head Blight (FHB) is a serious disease in all wheatgrowing areas in the world. FHB affects wheat by reducing yield and grain quality. Our objective is to characterize the relationship between FHB and grain yield. Three soft red winter wheat cultivars with different levels of FHB resistance (Truman, Hopewell and Cooper, moderately resistant moderately susceptible, and susceptible to FHB, respectively) were evaluated. Based on regression slopes, yield reduction per unit increase in FHB index varied among cultivars, being highest for moderately susceptible Hopewell, intermediate for moderately resistant Truman and lowest for susceptible Cooper.
Fusariose (FHB) est une maladie grave dans toutes les régions productrices de blé dans le monde. FHB s’attaque au blé, en réduisant le rendement et la qualité du grain. Notre objectif est de caractériser la relation entre la fusariose et le rendement en grain. Trois cultivars de blé tendre rouge d’hiver, avec différents niveaux de résistance à la fusariose (Truman, Hopewell et Cooper, moyennement résistant, modérément sensible, et sensibles à la fusariose, respectivement) ont été évalués. En se basant su les pentes de régression, la réduction des rendements par unité augmente en indice de fusariose qui varie selon les cultivars, étant le plus élevé pour les moyennement sensibles Hopewell, intermédiaires pour une résistance modérée Truman et le plus bas pour les sensibles Cooper.

"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".
