Project 1 - Development of Scab Resistant Soft Red Winter Wheat Varieties: Release high yielding, scab resistant SRW wheat varieties that are adapted to KY and the southern corn belt.
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.
- More information
Project 1: (1) screening: accurately characterizing resistance in existing cultivars, advanced breeding lines and populations by evaluating them under a range of disease pressures at two locations; (2) breeding: choosing parents, crossing them and selecting resistant progeny based on phenotype as well as genotype; (3) collaboration: growing and screening collaborative nurseries to facilitate germplasm exchange, broaden the diversity of sources used in the breeding program, and provide excellent pre-release multi-location data for candidate varieties; and (4) outreach: Through collaboration with our grains extension specialist and extension plant pathologist, we will screen a set of varieties and elite breeding lines in scab nurseries at two KY locations with and without fungicides. This data will be ported directly to the Scab Smart website.
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.
