The ideotype is a theoretical plant with model characteristics that aid cultivation and improve yield. Recent progress in genome editing technology is aiding the pursuit of this ideal in crop breeding. Breeding is relatively straightforward when the traits in question are monogenic in nature and show Mendelian inheritance. Conversely, traits with a diffuse, polygenic basis, such as abiotic stress resistance, are more difficult to harness. In recent years, many key plant domestication and improvement genes that act by increasing yield, grain or fruit size, or altering plant architecture have been discovered. I will attempt to show that (a) useful monogenic traits whose genetic basis has been unveiled can be molecularly tailored to achieve the ideotype; and that (b) manipulation of traits through state-of-the-art gene editing techniques can be use d to de novo domesticate wild relatives of crops that harbor polygenic stress resistance genes.
