Trait Study
FHB, Single Spikelet Inoculation, NxC, Bai03
Trait
Reaction to Fusarium graminearum
Reference
ReferenceGuo PG et al. (2003) AFLP and STS tagging of a major QTL for Fusarium head blight resistance in wheat Theoretical and Applied Genetics 106:1011-1017.
Protocol
Plants were inoculated by injecting 1,000 conidia onto the central floret of a spike, placed in a growth chamber at %100 humidity for 3 days, then returned to the greenhouse bench. Disease symptoms were measured as percent of symptomatic spikelets on each spike over 21 days.
