The overall goal of RYE-SUS is to develop, test and model gibberellin-sensitive semi-dwarf rye genotypes with optimised harvest index, improved lodging resistance, high yield potential and drought tolerance as well as minimised risk of ergot infestation for a sustainable intensification of grain production.
A comprehensive performance trial was conducted in 2021 in European and Canadian target environments for rye cultivation and documented the desired core functionality of semi-dwarf P-type hybrids (see picture).With the observed distinctness, uniformity and stability, all prototypes meet the requirements for approval as a variety on the basis of the Seed Trade Act. In addition, we conducted a partial life cycle assessment from cradle to farm gate considering all material and energy flows throughout rye and wheat production processes. 40.000 historical observations from more than 100 locations throughout Germany during 1983-2019 demonstrated that the carbon footprint of rye is generally smaller than that of wheat.
