Plant breeding is important to ensure that crops are well adapted to the environment in which they are grown and capable of resisting harmful pests and diseases, particularly if the use of fungicides and pesticides is to be reduced to protect the envi‐ ronment and improve sustainability. However, mainstream plant breeding methods can result in genetic monocultures that are susceptible to pests and diseases overcoming their resistance, and some breeding technologies such as GM are not accepted in organic farming.
