Still useful tips to read on hybridizing. Courtesy of Lenette Orchids

TIME OF DAY: Personally I make a cross when i have the time to
do so but many growers will only make crosses during mid-morning
hours. We do know that when taking slides of our flowers that there is
a tremendous difference in the quality of the slides you take. Late
morning is always best. Slides taken in mid-afternoon will be of poor
quality.

POD PARENT IS NORMALLY MORE DOMINATE: When
making crosses with parents that are not alike always remember that
the pod parent will dominate. So if you are after color for instance let
the parent with the most desirable color carry the pod if possible.
When breeding parents of like characteristics it generally does not
matter which plant carries the seed pod.

GREEN POD HARVESTING TIMES
PHALAENOPSIS-4 to 5 months
PHALAENOPSIS-novelties & species-5 to 7 months

With regards to time of day to pollinate a flower, I really don't understand the connection with photography. With photography the biggest issue is lighting. If you use artificial lights the quality of photos should not be affected by time of day. Most of the judging centers in southern Calif. do the judging and photography at night, but due to the skill of the photographers, these are usually very high quality award photos. If you use natural light, time of day and the season could affect the photos due to variables affecting daylight.

Another theory regarding time of day to pollinate is when flowers reach their peak fragrance. The idea here is that the fragrance is to attract a pollinator, so peak fragrance should correlate with peak fertility. I've never kept track of time of day of pollination, so don't know if it matters or not. My suspicion is that it is not a major factor in fertility. I think the most important factor affecting fertility is probably ploidy of the parents with diploids and tetraploids being the most fertile.

Yes, Ploidy is mentioned too.

COUNTING CHROMOSOMES: If we only knew the
chromosome count of all of our stud plants it would make hybridizing
a breeze. Unfortunately we must guess most of the time .Tetraploids
(double the normal chromosomes) normally breed easily if bred to
each other or diploids. Triploids are hybrids between diploids and
tetraploids and they normally are reluctant to breed.

There are exceptions re time of day to breed with. Maturity and freshness of flowers on species, i.e. bellina and equestris.

Re photography, I prefer natural daylight to take pictures of plants. I tried setting up artificial lighting indoor but did not like the result. If I need to be moving plants from greenhouse indoor to take pictures, I would not be posting as many pictures as I did. It has to be convenient. Inside the greenhouse, I can quickly round up a few plants and get quick photos. This is possible even during cold weather. I do not want to be moving plants when outside is 30 F.

You guys are rubbing off on me. I just experimented with my first hybridizing efforts. I put DTE onto my magenta violacea. OMG, we'll see if it takes.

Yay! More seedlings for long! Looking forward to seeing this cross bloom out. :)

Yuck, here is the seedpod with violacea magenta x DTE.

Glad to see your pod growing!!

Post subject:  Re: Hybridizing

Just be careful getting too excited... Sometimes those pods blow up and yield no seed. Hopefully that is not the case here. Might make an interesting cross.

It should be a clean cross and I bet you will get tons of seeds if you keep plenty water to the plant and keep it humid.

:) How to know whether the cross have been made before ? :think:

you can go to the RHS website and plug in the parents of the cross in question. it will tell you if its a registered cross. http://apps.rhs.org.uk/horticulturaldat ... dregister/ as far as i know, if its not registered, theres no way to tell if its been made before.

thanks for the PDF, will be useful.
The cross doesn't appear to have been registered as Bob says. However per OrchidWiz if you want to see a close genetic cousin - and can find a photo - its Miller's Bridge ( 94% match )
