What is meant by "variety" in the context of plant breeding?

In the context of plant breeding, "variety" refers to plants that have been bred for specific characteristics. This typically involves selecting plants with desirable traits, such as improved yield, disease resistance, or particular aesthetic qualities, and propagating them to enhance or stabilize these traits within a population. Varieties can arise from natural processes but are often intentionally developed through selection and breeding methods to meet agricultural or ornamental goals.

This targeted breeding process results in distinct genetic combinations that contribute to the unique qualities of the variety. By focusing on specific characteristics, plant breeders can cater to various needs, whether it's for crop production, environmental adaptations, or ornamental purposes.

The other choices do not accurately convey the definition of "variety" in plant breeding. For example, a group of genetically identical plants is more closely related to the concept of clones, while classifications of wild species or a term for all plant species do not reflect the targeted breeding aspect that defines a variety.
