ipomoea nil x purpurea cross successful!!!! so far!

this is a cross between crimson rambler(i purpurea) and wild blue i nil

Be sure to photograph the bloom! I'd love to see it.

A bit of history on Tony's experimentation(s)...

that was the cross 3-4 weeks after pollination.

MGMan,the variations in I.Purpurea are vast,and I am hard pressed to see anything in your new "hybrids" that differ from any of the self-seeders in my garden.Here is a pic of some of the variation on just one day.This is just a small representation of the many colors I see in a season.

Each of your hybrids still have the signature heart shaped hairy leaves and stems.Are there any distinct differences I am not seeing?

my light blue purpurea featured something new to me, a five star halo around the throat!

these are the parents of my cross.



this is the female parent

and here's the male parent

I`m only sharing my own experience with this kind of cross and have no comments or observations to make about yours other than your results look just like purpureas.

Did you remove the pollen from the pod parent the evening before and tie it closed? Did you tie the pollen parent closed the evening before? The next morning did you untie both of them and transfer the pollen to the pod parent from the other flower and tie the pod parent back?

Every time I ever followed this proceedure on purpurea x nil or vice versa the bud fell off later. The ones where I simply transferred pollen from one open flower to another crossing a nil with a purpurea resulted in pods but they proved to be selfed pods turning out to be exactly like the pod parent or a different color but apparently the same specie as the pod parent.

I did exactly what you said, but I do the anther removal and tying around dusk because the anthers are usually below the stigma making it hard to pollinate the flower; sometimes the flower gets pollinated before it even opens.


here is one of the crosses I did this morning with i purpurea x nil but I did six.

I think the photos are just of the parents...you haven't had any blooms from the results yet, right?

Yes, you remove the anthers before the morning in the evening. In the morning when you untie both you will see pollen on the pollen parent ready to apply. If you see the pollen already releasing in the pod parent when you go to remove the anthers then you need to choose another flower or try earlier in the day (a few hours can make a difference) because it already could be selfed and it would waste time and hinder results to mix the pollen. Around 5- 6 pm when it just begins to cool off is a good time and usually the anthers have not released the pollen yet. Tweezers are helpful with removal of anthers and with pollinating.

The pictures of your results should be intresting. Share with us when you get this grown out.

MGMan,

This is the previous results you posted on the blue nil and crimson rambler purpurea. It looks like your result is actually a result of mixed pollen with a different color purpurea. It looks just like a purpurea though I`m not judging your results but merely observing the traits shown in your result picture.

You may want to self the flowers on your results and try a grow out to tell more about the genetics of the cross you made. Many times a F1 may bear a srong resemblance to one of the parents and a selfed seeded grow out will reveal more about the inherited genetics in the cross. It would be an extremely rare occurance should you get a cross between a nil and purpurea.

Are you sure the little blue flower is not a hederacea. Could you give us a good clear picture of the sepal for Ron to check just to be sure?

here is the ipomoea nil, by the way, the temperature and weather conditions may play a big part in the success of a cross.

Hot weather is bad for seed setting but it will not prevent it necessarily.I notice more dropped buds on plants when the weather is very hot.

98% of my nil to nil crosses took and zero % of dozens of nil to purpurea crosses took. I did get one seed from a nil I didn`t remove the anthers and tie the night before but it was obviously a ipomoea nil when I grew it out. The seed was selfed from the pollen already in the flower. That is just my luck.

Good luck with your efforts. I always say it sure doesn`t hurt to try even when the odds are against you. I`m looking forward to seeing your results.

Karen

I should have my grow out ASAP

The somewhat blurry photo here
http://pics.davesgarden.com/pics/MGMan_1189195378_577.jpg
shows what look to be Ipomoea nil sepals.

My strong impressions echo those offered by the other members...

Dr.Yoneda was successful in achieving Ipomoea nil x Ipomoea purpurea hybrids after a staggering multitude of attempts and the sepals all look like Ipomoea nil...

The 5-segmented rounded halo visible on this bloom here
http://davesgarden.com/community/forums/fp.php?pid=3627877
is a feature common to many purpureas,but not seen on many (if any) I.nil...

The suppossed hybrid looks exactly in every detail like an Ipomoea purpurea and perhaps DNA sampling by one of the Universities would ultimately prove the genetic identity of the purported inter-specific...

Ron

MG MAN, keep upp the good work if you are for real. We have had so many charlotans here, you are just going to have to prove what you are saying. If you are for real, then don't get discouraged. Who knows? You could be the first one to do this cross, but not without documentage. Take those pictures and use that digital camera for months before you present a thread. I am behind you for experimenting and trying to do something unorthodox, but you have to show all the piers some evidence of your quest. Keep up the quest!!!! Frank

Another cross seems to be working so far, the bud in the front with the string tied around it.

this one look like it's working

What I do to see if it's working is that I carefully pull the sepals apart without ripping them to observe the developing ovary within a few days after pollination.

These were crossed with the same i. nil but with my hybrid purpurea as shown below.

here's the crimson rambler x early call blue seed pod almost ready to harvest.

Tony - This is a fascinating thread! I can't wait to read the next update! Great job with the photos and documenting your cross! I am anxiously awaiting photos of the blooms! Dynamite experiment!!!!

I hate to be the baring of bad news, while I was harvesting the seed from crimson rambler x early call blue, I pressed against it to see if it was hard and it mashed. the breakdown of the seed must have occurred. hopefully, it does not happen to the hybrid purpurea x early call blue cross.
