Info on where to find Dihaploid Corn information? - information on brontril

I'm doing a school project, and is on hybrid maize, but stresses more accurately, the double haploid maize. Obviously, this is relatively new because I can not find much information about everything. Has anyone information about it or where can I find them? Please! ASAP:) I do not know much about the double haploid maize specifically, and I need to know things like what started the difference between it and other hybrids. Any help would be very grateful!
