Source-sink dynamics between tillering and root development in wheat (Rootshape)
Aim of the study is to increase the yield of wheat by breeding and selection of new genotypes with adapted and balanced root and tiller development for an optimal yield potential. Thereby, we will clarify the role of the source-sink competition between root and tiller development at the growth stage 30 which is the end of the branching phase. The novelty of the approach is the integration of genotype-specific differences in tiller formation, phytohormone balance and root formation with regard to different nitrogen fertilizer strategies and sowing densities. Based on selected low and high branching genotypes, we will develop molecular and physiological markers for a selection of hybrids with root formation better adapted to branching potential for optimal water and nutrient supply of the grain.
