Nitrogen uptake and utilization efficiency in winter oilseed rape (Brassica napus L.)
Since there is an urgent need to increase production of agricultural commodities, whilst simultaneously minimizing environmental damage, nitrogen use efficiency (NUE) is becoming a major long-term global agricultural megatrend. Making use of genetic biodiversity to increase the resource efficiency of major crops is a promising strategy to increase the sustainability of agriculture.
My main research area is the exploration of strategies to improve the NUE of oilseed rape (Brassica napus L.). This includes the assessment of several plant traits under field and controlled conditions. For example, root traits are an important aspect to consider. In current projects we are screening oilseed rape and wheat for several roots traits which might be beneficial for increased nutrient and water uptake and therefore of interest for further breeding programs.
The analysis of genetic determinants associated with increased resource efficiency is one of my other research areas. In particular we are interested in understanding processes which make modern hybrid varieties more efficient, and how they can be optimized by innovative breeding strategies.
