Rose Cultivar Origin

Rosa L.

A genealogical record of a cultivar that determines its biological properties, such as winter hardiness, growth habit, and remontancy, based on parental lineage and breeding history.

In the reference 276 varieties crop Rose, where this is mentioned in the description.

The origin of a rose cultivar is a qualitative characteristic reflecting the genealogy and history of the plant's development. For modern cultivars, the pedigree may include up to 20–30 generations, combining various garden groups and original species forms.

Information regarding origin allows for the prediction of a crop's agrobiological parameters. For example, the presence of Rosa rugosa or Rosa spinosissima in the pedigree indicates increased winter hardiness, while the presence of Rosa chinensis suggests the established trait of repeat flowering.

For an agronomist, the genetic profile of a cultivar serves as a tool for selecting cultivation techniques, including pruning methods, requirements for winter protection, and spacing requirements. In addition to documentary evidence, the identification of the origin of modern rose cultivars is conducted using molecular analysis methods.
