Cadenza
Cadenza is a United Kingdom spring bread wheat that has become one of the most widely used reference genotypes in wheat genetics, including a sequenced hexaploid TILLING mutant population developed for gene-function research.

Cadenza is a spring bread wheat (Triticum aestivum) bred in the United Kingdom and grown as a breadmaking-quality spring variety. Beyond its use as a farm cultivar, it has become a standard reference genotype in wheat research.
Cadenza is one of two cultivars — with the durum wheat Kronos — used to build large chemically mutagenized (EMS) TILLING populations whose exomes were sequenced to allow researchers to find mutations in specific wheat genes. This work was carried out as a collaboration among UK and US research institutes, and Cadenza is also among the hexaploid wheats with a research genome assembly.

Use in research
Cadenza is widely used as a reference genotype in wheat functional genomics. A large TILLING population — a collection of lines carrying many chemically induced point mutations — was generated in Cadenza and had its exome sequenced, so that researchers can identify plants carrying mutations in a gene of interest without growing the entire population.
Official variety registration
Entries recorded for this denomination in official variety registers. Registration is a legal fact about marketing or ownership, separate from where the variety is grown or whether seed is available.
No entry for this cultivar is currently listed in the registers AgricultureID reads.
Entries that are no longer current
Each register decides separately, so these are grouped by instrument and jurisdiction and never combined into one timeline.

History records what an official source published at a point in time. Where the source states the date a change took effect, that date is shown; where it does not, only the date AgricultureID observed the change is shown, and it is labelled as such.
Each history is specific to one jurisdiction and one legal instrument. A right that expired in one country says nothing about a listing in another, and they are never combined.
A variety registration permits marketing; a plant variety protection right is ownership. They are granted by different bodies under different law and are never added together.
Entries are matched to this cultivar by identical denomination and by matching botanical species. Registers do not publish a global variety identifier, so a same-name entry in the same species could in principle be a distinct variety.
Registration is jurisdiction-specific, is granted under a particular legal instrument, and changes. A variety absent from a register may still be grown; confirm the current position with the responsible authority before acting on it. How registration is recorded.
Scope & limitations
Geographic scope: Documented United Kingdom spring bread wheat used internationally as a wheat genetics reference; agronomic adaptation is region- and season-specific.
Climate context: A spring bread wheat of temperate United Kingdom origin, now widely used as a research genotype.
- Adaptation and trait notes are region- and season-specific, and performance varies by environment.
- No release year or breeder is asserted here because reliable details were not confirmed; Cadenza is described mainly through its documented use as a research reference genotype.
