Abstract
Wheat doubled haploid (DH) could decrease the time to develop pure wheat lines by 3-4 years. We have been using the wheat DH to develop lines from F1 or BC1F1 plants derived from various combinations of FHB resistance genes, such as Fhb1, Fhb5, FHb6, FHB7 and some major QTL in both hard and soft wheat. About 200 DH lines are planting in the field in scab nursery in College Station for testing and they are also planted in the filed for yield testing. Harvested seeds will be distributed to collaborators for field testing in 2025. available DHLs were sent to genotyping center for Fhb1 marker testing.
