Summary
The project aims at exploring the potential of carbon and oxygen isotope partitioning measurements (related to photosynthesis and transpiration capacity) in wheat kernels as a biomarker to predict grain yield and protein in spring wheat cultivars.
Objectives:
The application and use of above physiological breeding traits are relatively cost-effective, fast, accurate and non-destructive.
- Evaluate 100 spring wheat germplasm based on screening of wheat kernels for ratio of carbon and oxygen isotope discrimination and growing them in the field locations (Swift Current and Indian Head).
- Determine the potential of using d13C and/ d18O in early generation selection of F2-F4 plants for higher yield/ protein predictability.
- Genotype the double haploid bread wheat population for traits related to carbon and oxygen isotope traits and identify gene locations (QTLs) for these traits in spring wheat.
