3. My Introductions

3.2. Gallery


3.2.1. Anacrusis
Dresden Gold X [(I.iberica x I.auranitica) x I. suaveolens]


A diploid onco hybrid was pollinated with the diploid dwarf bearded I.suaveolens (Syn. I.mellita). Such crosses are not too difficult and will result in an appreciable number of good seeds. The seedlings, however, are completely sterile as diploids. With the intention to double the number of their chromosomes the germinating embryos were colchicine treated in embryo culture. One of the seedlings that had survived this procedure proved to be fertile, indicating that doubling of chromosomes had taken place.

For lack of a fertile sister seedling the yellow arilbred Dresden Gold was used in both directions and gave rise to many very similar seedlings from which ANACRUSIS was selected.

3.2.2. Balalaica Music
Tet RC x tet OG
Reg. 1992


This is a very fertile tretraploid oncogelia.

After I had intercrossed the tetraploid RCs Tel Hashi, Werckmeister's Beauty, Dushanbe and Persian Garnet I felt that the resulting seedlings were still too much regelia in appearance. So I wrote to Sam Norris who shortly before had succeeded in converting onco hybrids to tetraploidy, and he was kind enough to send me some pollen of his new tets. Balalaika Music is one that resulted. Only because I was always looking for onco traits, especially signals, I didn't consider to introduce it. But Sharon McAllister found it to be good enough and especially its color very persistent in her hot climate, so she introduced it for me.

3.2.3. Barbarella
Unnamed tet RC x yellow I.pumila
Reg. 1991


Many years ago Dr.Werckmeister succeeded in producing a fertile aril-pumila hybrid by crossing a diploid RC with I.pumila. Such crossed usually lead to sterile triploids, but here apparently an unreduced gamete of the diploid RC had been fertilized. He named it MILTONIA. Theoreticians ever since predicted that amphidiploid aril-pums with two aril- plus two pumila-chromosome sets should be fully fertile, analogous to the tall amphidiploid arilbreds. The obvious thing was to make the cross again with the now available tet RCs and OGs. Barbarella was one of the first produced this way. It has fertile pollen but never set seeds. I raised many more aril-pums but fertility in all of them is much reduced. Occasionally I got a few seeds but even in the F2 fertility is not improved. It is of interest that Miltonia too was only male fertile as is Francesca Thoolen's Aladin's Gem.

3.2.4. Concerto Grosso
[(Gelee Royale x sib) x Anacrusis sib] x Invention
Reg. 1998


When I crossed the pentaploid Gelee Royale and its sib, which was in all probability a pentaploid too, I had in mind to possibly produce a hexaploid plant. Strangely enough the selected seedling was a very fertile amphidiploid. A year later the same cross gave me some seedlings which could have been hexaploids, but I discarded them all because they had three or four flowers narrowly crowded together on top of the stalk.

Concerto Grosso is an improved Anacrusis of the same height due to its I.mellita (I.suaveolens) ancestor.

3.2.5. Dotted Sunsuit
Yellow Anacrusis sib X [(I.auranitica x I.korolkowii) x (I.iberica x I.auranitica)]
Reg. 2001


¾-breds are regarded as difficult to produce. This cross yielded in many seeds which with the help of embryo culture gave lots of seedlings. Dotted Sunsuit was selected because of its fine dottings around beard and signal but also in the standards.

Dotted Sunsuit is also slightly fertile!

3.2.6. Gelee Royale
[I.auranitica x (I.hoogiana x Brass Accents)] X Dresden Gold
Reg. 1982


This is a counted 55 chromosome pentaploid which arose from an unreduced gamete of a triploid 2/3-bred AAB fertilized by a normal reduced AB gamete of a CGWhite-type. In the beginning there was a fertile regeliabred, I.hoogiana x Brass Accents. Its pollen was successful on the onco I.auranitica. Several seedlings resulted from this cross, all were apparently sterile triploids with 10 onco + 11 hoogiana + 12 TB chromosomes. Repeated pollinations with arilbred pollen resulted in many empty pods, but one day I discovered a good seed in one. Somewhat later I found another pod with two seeds. These gave me two plants by means of embryo culture. One of the two was named Gelee Royale.

Gelee Royale is fertile but sometimes only reluctantly. The few offspring seedlings by halfbred pollen so far seem to be amphidiploids. Even a seedling of GR with its sib was a very fertile halfbred.

3.2.7. Heimdall
Mondsee x Moon Dust
Reg. 1994


This child of Mondsee has 1/8 I.hoogiana "blood". I would like to draw attention to the fact that the great majority of the arilbreds are amoena types: standards light and falls dark, at the same time the standards are blue to bluish white and the falls in shades of brown to yellow. This one was registered because it is a true blue self although its fertility leaves much to be desired. In my garden it doesn't produce pollen and rarely sets seed.

Heimdall, by the way, is in the Germanic mythology the guardian at the celestial ladder.

3.2.8. Hidden Pink
Tetraploid OG seedl. x Vanity
Reg. 1998


It was one of my pet ideas to transfer the lycopene pigment onto the arilbreds. I raised many first generation seedlings from tet OG x pink TB and found a surprising high variability. Seedlings varied very much in color, aril phenotype and fertility, but there was not any showing but a trace of lycopene, and not the F2-generation either.

3.2.9. Invention
Anacrusis x sib
Dresden Gold x [(I.iberica x I.auranitica) x I.mellita] X SIB
Reg. 1994


It should be possible to select even smaller seedlings by backcrossing Invention to Anacrusis. So far all the Anacrusis descendants have been about 20 " (50 cm).

3.2.10. Iridescent Orange
(Invention x Gelee Royale) x Concerto Grosso
Reg. 2001


This variety got the sharp and large signal from its parent Concerto Grosso.

Most seedlings with Anacrusis in the parentage had been dark reds, so I was glad to have a presentable one in another shade. Its color is a little variable depending on the climate prevailing, as pictures from USA have shown.

3.2.11. Lady Bernstein
Lady Mohr x Bedouin Woman
Reg. 1980


Quarterbreds are rather sterile, but some of them give a fair amount of viable seed when they are pollinated by a halfbred. My Lady Mohr x Bedouin Woman seedlings varied a lot in every respect. I found quite a few which were entirely sterile, others were normally fertile. It has been theorized that the cross ¼-bred x ½-bred gives again ¼-breds and functional ½-breds, but I think there will be many aneuploids among them too.

3.2.12. Mondsee
(Esther Fay x I.hoogiana) x Dresden Gold
Reg. 1981


Regeliabreds from I.hoogiana usually look like inferior TBs, but they are hardier than C.G.White-types and can be crossed with them to give fertile hybrids.

Mondsee has proven to be fully winter hardy in climates much colder than mine and grows happily under ordinary TB conditions.

3.2.13. Sky and Earth
Bangladesh x Desert Dove
Reg. 1980


This was my first introduction which I am no longer growing. May be it is still in the USA. Note the common arilbred pattern: blue above – red-brown below.

3.2.14. Surpassing Yellow
(Invention x Gelee Royale) X Concerto Grosso
Reg. 2001


A sib to Iridescent Orange which also broke through the red parade of the Anacrusis descendants.

A very good grower, it has persisted in the open garden for several years.
