The spring soil nitrate test that’s standard in Western Canada is not always useful in Eastern Canada, where rainfall tends to be heavier.» Read more...
What if corn breeders had access to molecular markers for qualities like Gibberella ear rot resistance and kernel dry down rate? Researchers at Agriculture and Agri-Food Canada’s Ottawa Research and Development Centre (ORDC) have begun to understand the molecular mechanisms influencing these traits, which means corn breeding is about to get smarter – and faster.» Read more...
