Research Project: Breed FHB Resistant Cultivars Via Doubled Haploid and MAS

Location: Crop Production and Protection

Project Number: 0500-00053-005-175-G
Project Type: Grant

Start Date: May 1, 2024
End Date: Apr 30, 2026

Objective:
1) Pyramid multiple major FHB resistance genes through marker-assisted backcrossing. 2) Develop doubled haploid lines (DHLs) using established DH system in the Texas A&M AgriLife research Amarillo with an aim to obtain 100 DHLs from each of the 10 crosses. 3) Identify the resistant DHLs through marker assisted selection (MAS).

Approach:
We will integrate MAS into the DH development process to effectively introgress both major and minor FHB resistance genes/QTL into locally adapted cultivars. Breeders will provide their preferred crosses with major genes (Fhb1, Fhb6, Fhb7) and/or minor genes/QTL in the adapted cultivars background. DHLs will be produced.
