Research Project: Breeding Scab Resistant and Low DON Hard Winter Wheat Varieties for the Northern Great Plains

Location: Hard Winter Wheat Genetics Research

Project Number: 3020-21000-011-21-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2018
End Date: Aug 31, 2021

Objective:
1. Increase efficiency of individual breeding programs by developing phenotypic and genomic selection models through coordinated efforts of pyramiding major and minor genes leading to the development and release FHB-resistant varieties with lower levels of DON. 2. Characterize genotype x fungicide treatment responses for enhancing FHB resistance and the reduction of DON.

Approach:
1. Make crosses among lines with minor and major genes for FHB tolerance and low DON accumulation. 2. Integrate improved FHB phenotyping using in vitro detached leaf protocol with field and greenhouse-based FHB screens to improve and validate our selection protocols. 3. Screen/select lines through molecular markers, genome-wide association studies, and genomic selection. 4. Use the prior and current FHB data as training populations and the in vitro detached leaf assay to identify the best FHB tolerance and lowest DON lines.
