Breeding potatoes is like herding cats

So says potato geneticist Ingo Hein. It’s due to the chaos which results when two potato plants are crossed. The result can be one of tens of thousands of variations, which is challenging when you just want to combine a few favourable traits. As Professor Hein explains, potato geneticists are using all the tools in the box to painstakingly come up with new potato varieties to suit the demands of modern agrifood in a changing climate.
