International Research Training Group: Modelling Material Flows and Production Systems for Sustainable Resource Use in Intensified Crop Production in the North China Plain, Modelling Material Flows and Production Systems for Sustainable Resource Use in Intensified Crop Production in the North China Plain - GRK 1070 - Subproject 2.2: Modeling Novel Breeding Schemes for Improving Water- and Nitrogen-Use Efficiency of Maize and Wheat for Sustainable Cropping Systems in the North China Plain

Description: In China agricultural productivity needs to be increased by developing improved strategies for sustainable resource use in intensified cropping systems. Among other factors, the genetic potential of cultivars plays an important role in production systems.Adopting novel breeding approaches based on doubled haploids (DHs) can speed up the process of developing new varieties substantially and rapidly provide suitable cultivars for new cropping systems. Therefore, a first objective of this subproject is the improvement of the DH technology in maize. This implements efforts on increasing induction rates by investigating new inducer lines. In addition, intensive collaboration aims to improve the chromosome doubling procedures. The second objective is to find theOptimum use of DH approaches in hybrid maize breeding determined by means of modelling and simulations.
