Thoughts on Breeding

Like nearly all horticulture there is a rhythm to cultivating orchids; the days shorten and lengthen and as the seasons pass and turn, plants initiate growth, flowering and set seed. In the artificial confines of our homes and greenhouses the grower attempts to manage the rhythm by withholding or supplying light, water, nutrients, etc. to trick the plant into behaving naturally mainly for the purpose of encoraging blooms.
In our setup we have prioritized plant functions as follows:
- Root growth, development, and survival;
- Foliage growth, development and survival; and
- Floral display.
That being said, I have experimented with hand pollination of flowering orchids. So far my results have been mixed, out of the six or so attempted crosses only three have set pod. My first cross was attempted in November of 2005 as Brassavola nodosa x Laelia anceps 'Los Osos' which is a remake of Bl. Aurora which was registered a little over 10 years agon in 1995. This is a reciprocal cross as the registered grex has L. anceps as the pollen parent. This pod has begun to turn yellow and will be ready for harvest this week.
I'm expecting quite a bit of diversity for this cross, spotted flowers and improved thermotolerance. We'll see in a few years.
My next cross occured in February of this year between Anacheilium Green Hornet and Lc. Trick or Treat. I don't know what to expect from this cross, perhaps clusters of non resupinate orange flowers?
My final cross that has set pod is between Caulaelia Mizoguchi 'Cloud Cover' HCC/AOS and Slc. Tsiku Paradis. Tsiku Paradis is a miniature with Sophronitis cernua as a parent; it is truly tiny. I'm expecting the progeny to be much more compact than the Mizoguchi parent with light pink, yellow, or orange flowers held on a spike and good cool tolerance.
I'm nervous about these crosses as there are so many opportunities for things to go wrong. The pods may not have any viable seeds, the progeny may be weak growers, or have ugly flowers. I am expecting to have some of these negative results but am also holding out the hope that one of these crosses results in something new and innovative.
