Breeding of Sorghum bicolor hybrids for improved biomass and biogas yield
Analysis and enhancement of sorghum pollen fertility under chilling stress
My research covers various aspects of adaptation and hybrid breeding of sorghum (Sorghum bicolor), an originally tropical plant, as a novel bioenergy and fodder crop in temperate Europe. Thanks to its diabrotica resistance, drought tolerance and nutrient efficiency, sorghum is a promising alternative to maize. However, several aspects such as chilling tolerance in both juvenile and flowering stages, maturity, energy density and yield stability need to be enhanced to make it fully competitive.
Approaches on applied breeding comprise the design of novel ideotypes for biogas generation with an improved energy density and agronomical properties, and the development of new, adapted base material within genetically diverse heterotic pools, aiming at an optimal exploitation of heterosis and combining ability for yield and abiotic stress tolerance. Further, understanding and enhancing of sorghum pollen fertility under chilling stress represents a major research focus.
