Garden classification of irises

Garden classification of irises

According to the modern international classification of irises, developed by the American Iris Society (AIS), it is customary to distinguish 15 garden classes:

1. Tall bearded (TB) - Tall bearded

2. Border bearded (BB) - Border bearded

3. Miniature tall bearded (MTB) - Miniature tall bearded

4. Intermedia bearded (IB) - Intermedia bearded

5.Standard dwarf bearded (SDB) - Standard dwarf bearded

6. Miniature dwarf bearded (MDB) - Miniature dwarf bearded

7. Aril (AR) - Arils

8. Arilbred (AB) - Arilbreds

9.Siberian (SIB) - Siberian

10. Spuria (SPU) - Spuria

11. Japanese (JI) - Japanese

12. Louisiana (LA) - Louisiana

13. Californian (CA) - California

14. Species (SPEC) - Species hybrids

15. Interspecies (SPEC-X) - Interspecies hybrids

Grades 1-8 include "bearded" irises and grades 9-15 include "beardless".

The Russian Iris Society (ROI) has adopted the following garden classification of irises - also from 15 classes:

1.TB (Tall bearded) - Tall bearded

2.SMB (Standard median bearded) - Standard medium-sized bearded

3. SFMB (Small-flowered median bearded) - Small-flowered high bearded

4. IMB (Intermediate median bearded) - Connecting medium-sized bearded

5. SDB (Standard dwarf bearded) - Standard dwarf bearded

6.MDB (Miniature dwarf bearded) - Miniature dwarf bearded

7. (-) AB (Non-Aril-like Arilbreds) - Non-Aril-like Arilbreds

8. AR & (+) AB & AB (Arils and Aril-like Arilbreds) - Arils and Aryl-like Arilbreds

9.SIB (Siberian) - Siberian

10. CHR (Chrysographes) - Chrysographes

11. JA (Japanese) - Japanese

12.SPU (Spuria) - Spuria

13.LA (Louisiana) - Louisiana

14. CA (Californian) - California

15. OT (Others) - Others

As in the international classification, grades 1-8 include "bearded" irises, while grades 9-15 are "beardless". In contrast to the international classification, from the class "Siberian" into a separate class - "Chrysographs" - 40-chromosomal cultivars have been isolated, which have a phenotype different from the Siberian irises. The ROI Presidium recognized it expedient to consider the presence of at least 100 varieties as a criterion for separation into an independent class; the classes "Species hybrids" and "Interspecific hybrids" are combined into one class - "Other".

According to the ROI, as of 01.01.2010, the following number of iris varieties were recorded in the Russian Federation:
