Research Project: Improvement of Soft Winter Wheat That Is Resistant to Fhb Adapted to Eastern Usa Project Number: 0500-00053-003-88
Project Type: Grant

Start Date: Jun 08, 2014
End Date: Jun 07, 2015

Objective:
Project 1 - Improvement of Soft Winter Wheat that is Resistant to FHB and Adapted to Indiana: 1) Increase acreage planted with varieties with improved FHB resistance to reduce DON in the US grain supply; 2) Increase efficiency of coordinated project breeding programs to develop and release FHB resistant varieties; 3) Develop 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. Project 2 - Male Sterile Facilitated Recurrent Selection for FHB Resistance (MPI-5): The objective of this project is to advance male-sterile facilitated recurrent selection populations that have been developed to combine genes for FHB resistance from multiple sources in soft winter wheat backgrounds adapted to the eastern U.S. Project 3 - Coordinated Phenotyping of Uniform Nurseries and Official Variety Trials: Screen and Evaluate approx. 450 unique advanced breeding lines and released cultivars for FHB resistance.

Approach:
Project 1: Two replications of the RILs plus the parent lines will be grown in 2011-2012 at Lafayette, IN in the misted nursery and 1 replication will be grown at each of Vincennes and Evansville under natural conditions and seeded in disced corn residue. Project 2: Will use the seed produced and selected in the previous year, inoculate with FHB spores at flowering and begin to derive lines by selecting individual FHB resistant plants. Project 3: 1) Phenotype advanced breeding lines that are candidates for release: 2) place FHB and other agronomic, disease resistance, and quality data in database: 3) report on purification and seed increase of the best lines.
