Known resistance genes

Field monitoring is an essential activity in order to optimize diseases management and apply IPM at farm level. Many countries have well-established control thresholds, which can be used as background for deciding whether or not to apply a fungicide. This guideline describes, how to do assessments and gives examples of thresholds recommended in different countries.

Specific genes known and characterized: Not known

Knowledge of non specific genes: Polygenic resistance:

Fhb1 from Sumai 3= 3B;
Fhb2 from Chinese wheat=6B

Other QTL's on all wheat chromosomes except 7D.
The most stable on: 1B, 1D, 2B, 2D, 3A, 3B, 5A, 6B.

DON resistance relate to 2D, 3B and 5A

Reduced incidence related to 2D, 3A,5A

Known markers used in breeding: Only markers for Fhb1 on 3BS.

Availability of genes in cultivars:

Fhb1 not yet available in European cultivars. Old European materials have combinations of 1B, 2B, 3A, 5A and 6B
