At Southern Cross University I visited a long-term collaborator to work on several manuscripts that we intend to publish based on the research done under our previous GRiSP project on “Enhancing the sustainable use of phosphorus (P) in rice systems through the development of varieties with reduced grain P concentrations”. We have advanced two manuscripts to the final draft stage and discussed various options for a third manuscript, which would include another partner from AfricaRice.
As our previous project has been completed, we discussed possibilities to continue our very productive collaboration in the future. A common point of interest remains the reduction of seed P concentrations. As we have concluded in the GRiSP project that natural variation within the rice gene pool is not sufficiently high to exploit in breeding, we are now considering testing for mutants at several potentially important genes, and to combine different mutants through normal cross breeding.
