Enhancing pre-harvest sprouting tolerance in wheat
Background: This would be a continuation of work started under a GF2 project that was funded by WGRF and MB GF2 funding. It was started just as we were starting up and MWBGA contributed research management as an in-kind contribution. Lori-Ann wrote contracts and coordinated reporting to all the funders.
Lead Researcher: Belay Ayele, University of Manitoba
Collaborators: Dr. Curt McCartney & Mark Jordan, AAFC – Morden
Start Date: 2019
Project Length: 3 Years (2019-2023)
Project Status: APPROVED – Contracting
This project focuses on a newly developed wheat double haploid population derived from a cross between preharvest sprouting (PHS) resistant line RL4137 and PHS susceptible cultivar Roblin for which the genotypic and phenotypic studies are in progress as a collaborative project between Dr. Ayele’s lab and the labs of Dr. Mark Jordan and Dr. McCartney at AAFC-Morden. Still early discovery research moving one step closer to incorporation in a variety. How well do new genetic traits discovered over the last 3 years express PHS tolerance in a new cross and can we use new technologies to see it earlier? The work proposed in this LOI extends the scope of the study beyond the genetic/QTL analysis to integrate genome wide RNA-sequencing (RNA-seq) and targeted metabolomics approaches to identify novel genes and molecular variants that can accelerate wheat breeding for PHS tolerance.
- Novel genes for improving tolerance of wheat grains to preharvest sprouting.
- New molecular variants/markers to facilitate breeding for sprouting tolerance, and genomic resources to the public functional genomics data repository.
- Adapted wheat germplasm with optimum dormancy, and highly qualified personnel in the area of wheat genomics.
