Definition
- Noun:
- A plant variety produced by selective breeding: A 'cultivar' is a distinct plant type that has been deliberately developed from a natural species through controlled cultivation and breeding to possess specific, desirable characteristics. It is maintained through specific propagation methods to preserve its unique traits.
Usage Examples
- Noun:
- This new apple cultivar is prized for its exceptional sweetness and disease resistance.
- Botanists registered the rose as a unique cultivar with the international authority.
- Many popular garden flowers are cultivars that do not exist in the wild.
Advanced Usage
- In botanical nomenclature: The term is often used in formal plant names, appearing in single quotes or preceded by "cv." For example, 'Bloodgood' is a cultivar of the Japanese maple.
- In agriculture and horticulture: Refers to a plant line kept distinct and uniform by vegetative propagation (like cuttings or grafting) or by careful seed selection.
Variants and Related Words
- Cultivate (verb): To prepare and use land for crops or gardening; to grow plants.
- Cultivation (noun): The action of cultivating land or plants; the process of developing a cultivar.
- Variety (noun): In botanical taxonomy, a rank below subspecies; sometimes used more loosely, but a 'cultivar' is a cultivated variety, not necessarily a botanical variety ().

- The defining characteristics of a cultivar (e.g., flower color, fruit size, growth habit) must be stable and reproducible.
