t0“Effectiveness of marker-based selection for Fusarium head blight resistance in spring wheat”
e1“In the cross Sumai 3/Swedget the selection for QTL alleles from 3B and 5A resulted in a 63.4% reduction in DON content, and a 51.8% reduction in the FHB index”
e2“DON content and FHB index were significantly reduced in both crosses in the genotype classes with two stacked donor QTL on chromosomes 3B and 5A in comparison to genotype classes with no donor QTL”
e3“was evaluated in field trials over two years (2008, 2009) following artificial inoculation with Fusarium culmorum”

- Intervention effect In the Sumai 3/Swedget cross, selecting for 3B and 5A donor QTL alleles reduced DON content by 63.4% relative to classes without donor QTL.
- Intervention effect In the Sumai 3/SG-S 191-01 cross, selecting for 3B and 5A donor QTL alleles reduced DON content by 35.9% relative to classes without donor QTL.
- Intervention effect In the Sumai 3/SG-S 191-01 cross, selecting for 3B and 5A donor QTL alleles reduced the FHB index by 31.9% relative to classes without donor QTL.
- Intervention effect Classes with two stacked donor QTL on 3B and 5A had significantly reduced DON content and FHB index compared with classes without donor QTL in both crosses.
- Intervention effect The single effect of the 3B donor-QTL allele was significant only in the Sumai 3/Swedjet cross.
- Association Presence or absence of awns affected DON content and FHB index in both populations, with significance only in the Sumai 3/SG-S 191-01 cross.
- Intervention effect Selection for fully awned genotypes reduced DON and FHB index in classes with neither donor QTL nor the 3B QTL.
- Association The awnedness effect on FHB resistance is probably greater for reducing FHB symptoms than for reducing DON content.
- Method / resource Marker-based introgression of 3B and 5A resistance QTLs can enrich traditional breeding populations for resistance types.
- Recommendation A similar effect to marker-based selection can probably be reached by indirect selection for some FHB-related traits; the marker effect need not be large in all crosses.
