Hello, all.....Should one ever use an old iris in
hybridizing? That depends. One must weigh the form of the modern
hybrids against much older hybrids, and what must also be taken into
consideration are the ancestors of these irises. (It is a good winter
pastime to study the AIS checklists.) So why did I use a 70-year-old
hybrid in a cross? I am talking about the oncobred (an iris that has no
regelia bloodlines so it is categorized as OB...1/2 onco) 'Capitola' (Reinelt,
1940). It was used a lot in the 1940s and 1950s with 'Snow Flurry' and
'New Snow' to create a lot of hybrids known as "Mohrs", flowers mostly in
violet, maroon, and similar colors. It fell out of favor with arilbred
hybridizers and has not been used much since, but I felt it still had
potential. It is only pollen fertile, so I risked using it with an SDB
realizing that there was the possibility that the resulting seedlings would lose
aril characteristics. I used, as a pod parent, Paul Black's SDB 'Amusing'
(2004). I was interested in 'Amusing's coral pink beards and pink
tones. 'Capitola' is a dark red violet, so I also risked the fact that
violet is a dominant tone. The resulting seedling that bloomed this year
was an arilmedian in tones of buff-gold with some brown and burgundy dotting and
veining. The beards are bright orange, and there is a diffused signal
spot. It has nice domed standards (though one standard was slammed by a
wind gust when the picture was taken) and rounded falls. I can honestly
say that, in this case, the choice to use an historic iris was the right
one. This one will be part of my "stable" of breeders for fertile
arilmedians. See photo below.
