Breeding innovations for resilient cereal cropping systems

Subproject: Understanding innovation decisions for winter wheat breeding in Germany (year 1-3)
Innovation in new plant varieties is the result of a number of decisions taken by different interrelated actors who decide whether to do research and in what direction, and what invention to pursue for commercial distribution.  These decisions are enlarging the knowledge basis for future breeding and at the same time are the prerequisite for variety choice of farmers. Against this background it is of primary interest to understand what determines the breeding decisions of breeders in the interplay of the different actors. This subproject informs us about the expectations of the different actors in the agricultural innovation system concerning the evolution of future cultivation systems, natural, market and political situations. Furthermore, we try to know more about actors’ reaction to these expectations as far as they impact winter wheat breeding or the benefits and costs stemming from different traits of varieties.

Subproject: Determinants of market demand for different traits of winter wheat by farmers - A choice experiment (year 4-5)
Large amounts of pesticide are used in farming in Germany to maintain plant health and productivity, despite their high cost and negative impact on biodiversity, water and soils. Using wheat as a case study, we hypothesise that, when wheat prices are high, farmers will maximise yield and use pesticides to compensate for any shortcomings in disease resistance but will favour resistant varieties when prices are low. To test the hypothesis, we conduct a choice experiment, a stated preference method, Farmers were randomly selected and interviewed in-person between December 2018 and April 2019. In the choice experiment, farmers were asked to choose their preferred wheat varieties from a set of hypothetical varieties which differed in characteristics selected based on the basis of prior interviews with farmers and experts.
