Editing Triticale (section)

== Species ==

Triticale hybrids are currently classified by ploidy into three [[nothospecies]]:<ref name=taxo-Hammer>{{cite journal |last1=Hammer |first1=Karl |last2=Filatenko |first2=Anna A. |last3=Pistrick |first3=Klaus |title=Taxonomic remarks on ''Triticum'' L. and ''×Triticosecale'' Wittm. |journal=Genetic Resources and Crop Evolution |date=January 2011 |volume=58 |issue=1 |pages=3–10 |doi=10.1007/s10722-010-9590-4|s2cid=24403249}}</ref>
* [[× Triticosecale semisecale|× ''Triticosecale semisecale'']] <small>(Mackey) K.Hammer & Filat.</small> – [[tetraploid]] triticale. Unstable, but used in [[bridging population|breeding bridging]]. Includes the following crosses:
** ''[[Triticum monococcum]]'' × ''[[Secale cereale]]'', genome AARR;
** Alternative crosses, genome ABRR ([[mixogenome]] A/B).
* [[× Triticosecale neoblaringhemii|× ''Triticosecale neoblaringhemii'']] <small>A.Camus</small> – [[hexaploid]] triticale. Stable, currently very successful in agriculture. May be produced by ''Secale cereale'' × ''[[Triticum turgidum]]'', genome AABBRR.
* [[× Triticosecale rimpaui|× ''Triticosecale rimpaui'']] <small>Wittm.</small> – [[octaploid]] triticale. Not completely stable, mainly historical importance. May be produced by ''Secale cereale'' × ''[[Triticum aestivum]]'', genome AABBDDRR.

The current treatment follows the Mac Key 2005 treatment of ''Triticum'' using a broad species concept based on genome composition. Traditional classifications used a narrow species concept based on the treatment of wheats by Dorofeev ''et al.'', 1979, and hence produced many more species names. The genome notation follows {{section link|Taxonomy of wheat|Genome}}, with the rye genome notated as R.<ref name=taxo-Hammer/>
