Research VDHR-SWW


Variety Development and Host Resistance Southern Soft Red Winter Wheat (VDHR-SWW)

VDHR-SWW Research Area Committee  Members as of:  1/1/21
Chair, Steve Harrison, Louisiana State University
Richard Boyles, Clemson University
Allen Becker, GrowPro Genetics, LLC

Project Description:

The VDHR research area will be Uniform Nursery based in the case of soft winter wheat and spring wheat. States will be aligned with the uniform nurseries as follows: Uniform Regional Scab Nursery for Spring Wheat Parents (ID, MN, MT, ND, SD, WA); Uniform Northern Winter Wheat FHB Screening Nursery (IL, IN, KY, MI, MO, NY, OH); Uniform Southern Soft Red Winter Wheat FHB Screening Nursery (AR, GA, LA, NC, SC, VA). VDHR research will be commodity-based in the case of barley, durum and hard winter wheat coordinated projects.

Each Uniform nursery will be coordinated by a regional committee. Nurseries will be conducted in collaboration with a pathologist wherever possible and a subset of promising entries may be grown at multiple locations in Integrated Management Trials. The nurseries will also be evaluated for milling and baking quality, and haplotyped at the USDA regional genotyping labs. The most promising lines may be entered in the nurseries for a second year of testing at the lines originator’s request. Collaborators will submit candidate parents for crossing, and prebreeding populations derived from these crosses/populations will be shared. Mapping of new resistance sources will be accomplished through joint phenotyping of populations. All collaborators will screen varieties and breeding lines entered into statewide performance trials for FHB resistance and provide this information to growers.

FY20-21 Research Priorities Derived from Action Plan Goals:

  1. Increase and document the number of varieties with improved FHB resistance and high grain yield and grain quality that are tested in statewide variety trials and available to farmers, to reduce DON in the US grain supply.
  2. Increase efficiency of coordinated project breeding programs to develop and release FHB resistant varieties.
    • Enhance cooperation and coordination of research among programs.  For example, phenotypic data should be uploaded to the T3 database, and early generation populations would be shared among programs.
  3. Evaluate and implement new breeding technologies and germplasm to further enhance short term and long-term improvement of FHB resistance and to efficiently introgress effective resistance genes into breeding germplasm.
    • Enhance selection efficiency through technologies such as genomic selection, marker-assisted selection, doubled haploid production and/or high throughput phenotyping.
