Factors influencing Fusarium head blight (FHB) occurrence and yield losses
in winter wheat have extensively been studied through the years; however, reports on the
relationship between FHB traits and yield are conflicting. In addition, studies neglected the
relationship between FHB traits and thousand-kernel weight (TKW). This study evaluated the
variability in the relationship between FHB traits, TKW, and yield under field conditions, using
40 commercial winter wheat cultivars differing in resistance/susceptibility to FHB. In general,
the FHB index had greater relation to yield, while Fusarium-damaged kernels (FDK) was more
related to TKW. The relationship between yield, TKW, FHB index, and FDK was also determined
by resistance/susceptibility of winter wheat cultivars. Fusarium-damaged kernels influenced yield
more in moderately resistant (R2 = 43 %) than in susceptible/moderately susceptible cultivars (R2
= 27 %). The influence of the FHB index on TKW was weak (R2 = 9 %) in... susceptible/moderately
susceptible cultivars and in moderately resistant ones (R2 = 1 %). The potential to predict TKW
from yield under pathogen pressure was limited due to the moderate-to-positive correlation
between yield and TKW (r = 0.349, p < 0.001). This study provides insights into factors that
influence TKW under FHB pathogen pressure and gives direction to more efficient and reliable
investigations on grain resistance toward FHB.
