I've been doing some grafting work in Ipomoea species, and all of the papers I've referenced recommend a variety of I. nil 'Kidachi' (or sometimes 'Kidachi-Asagao', but asagao just means morning glory in Japanese). This seems to be a dwarfed japanese morning glory which produces thicker, shorter stems, which makes it ideal as a rootstock, while retaining the floriferous nature of many I. nil varieties.

However, I can't find this variety anywhere. Has anyone heard of this, or know where I might look for it?

Thanks.

Hi Paul,

That is a new one for me. I am pretty sure I don't have it. I can ask about it from some of my Japanese morning glory growing friends.

That's an interesting project grafting Ipomoea nil. You're the first person I have met who is grafting this annual species. Have you had success with other members of the Convolvulaceae?

There is a mutant called Uzu Kobito, but it's kinda rare.

Here's some research

I'm grafting other species of Ipomoea to nil, which improves the flowering and seed production. It started with sweet potato, but expanded in scope to others that are not typically seed propagated. I'm trying to put together genetic pools of true seed from which to do adaptability selection (large quantities of seed are required because the rate of off-types is so high). I've had some size compatibility trouble, with scions being thicker than my seedling rootstock, and was hoping to improve things if I could find the recommended variety.

Thanks for your input.

I put kidachi morning glory in Google Translate and got this:

木立朝顔

Which in Romaji is kodachi Asagao.

I searched using Chrome using
木立朝顔 and got many photos, many which were Ipomoea carnea, which produces quite a woody stem.

Wow, I can't believe I didn't think of that. I've been studying Japanese, and yet it didn't even occur to me to search Japanese pages (and I had forgotten that Google filters out foreign language pages by default).

So many pages on キダチアサガオ, and many of them do reference Ipomoea crassicaulis, or I carnea subsp. fistulosa, as you said. I'm going to have to do some reading.

Thanks so much.

(and as a side rant, while I greatly appreciate the work that's being done to better understand the relationships of genetic groups these days, the accelerated reorganization and renaming of hierarchies threatens to undermine all of the strengths, and even the purposes of having official taxonomies. We need a central registry or something where you're not allowed to publish a paper proposing new names and organization without adding them and your proposals to the registry with proper links to the current and historical taxonomy...)

Good luck with your endeavors. Let us know how it goes.
