How are new plant varieties created?
In traditional plant breeding, new varieties are Developed by selecting plants with desirable characteristics or by combining the qualities of two closely related plants through selective breeding. For example, these characteristics may be resistance to specific pests or diseases, or tolerance to climatic conditions.
How are new plant varieties developed?
Plant breeders produce new plant varieties Using genetic engineering and genome editing Traditional breeding methods are used for many of the same reasons. … genome editing allows scientists to make changes at precise locations in the DNA of plants, animals or other organisms.
