Collaborative project: Source-sink dynamics in tillering and root development in wheat - subproject 2
Project
Project code: 2814603413
Contract period: 01.06.2015
- 31.05.2018
Budget: 332,367 Euro
Purpose of research: Experimental development
Overall goal of the "Rootshape" project was to increase yield potential in spring wheat via the generation of lines, in which root development is ideally adapted to the genotype-specific tillering potential. Wheat lines with contrasting tillering potential were crossed and the progenies of a DH population were examined for correlations between grain yield, tiller and root traits. Positive correlations were found between grain yield and tiller reduction as well as between the number of tillers and nodal roots. Metabolite and phytohormone analyses identified tillering-promoting hormones, which can be used as physiological markers for tillering potential. The present results can be used for the identification of breeding lines with new trait combinations and will serve for the optimization of marker-based selection and the estimation of breeding values.
