Passiflora incarnata hybridizing

The hybrids I grow just set a load of fruit the last few weeks. They’ve had more fruit set this summer until now. The more I grow these the more it looks like they need a few weeks of dry weather to really produce much, otherwise it’s just flowers, growth, and few if any fruit.

We reliably get dry weather by late August or September, so I don’t think it’ll be an issue. And the years we get an uncharacteristically dry June or July, which can be tough on my other plants, at least I’ll be rewarded with plenty of passion fruit.

I reached out to him as well for passion fruit seeds. I will follow up with the community if they’re Available. The Ukrainian seeds will likely be available in November and I will follow up then

Edit: missed the deadline by a week. He does not sell seeds but this society does. Sign up and book mark this post in 11 months!

I received word back. The message lists the varieties. I am getting prices. I will have the seeds inspected (they’re being shipped internationally) and then shipped to my home, and then I will ship them out to individuals. I will follow up with individuals who messaged me either to gauge interest but please help me by following up.

I sent seeds to Blake Cotron in the USA via regular Ukrainian state mail. Everything arrived perfectly in 10 days. Without certificates or licenses…

Follow up question regarding polyploidy:

In doing some homework, I read this

Are all white P. incarnatas polyploid? Because I saw several wild this year.

@Vitamin I really love and appreciate your list and all the information you’ve managed to compile for us, but could you please clarify this for me?

Sorry for my ingrorance, but I’m having some difficulty understanding what exactly you’re saying about DK-21. Is ‘Bitor’ a shortened misspelling of the parent ‘BITOP 7/5,’ or is it its own separate variety?

Thanks

BITOP 7/5= BITOP=‘Bitor’

‘Bitor’ is a mistake, an incorrect name.

“DK-21 X BITOP 7/5” is a separate plant, the result of crossing.

Ok, thanks for the clarification.

Do you have a brief description of “DK-21 X BITOP 7/5” (e.g. similar to DK-21 and BITOP 7/5 but ______) or is its characteristics still to be determined?

Very similar. There may be a larger harvest, larger fruits.

HI Roman,
In your experience, do your hybrids sucker profusely underground and produce lots of new shoots? Or do they tend to stay put in one location?

P. incarnata are prolific with underground shoots. This makes selection very challenging, as they sprout up everywhere, and isolation between seedlings would need to be large enough so that there is no intermingling. I have experienced this already, it is a significant challenge.

What do you think?

Do all of your hybrid passionfruit freeze to the ground and regrow every year (are any kept in pots)? What is the coldest you’ve seen?

2 out of 6 of my Incarnata x edulis from previous post have flowered indoors as rooted cuttings:

Almost done for the year, but I guess the year is almost done too.

Hello.
Hybrids of incarnate grow just like incarnate.
I have not tested polyploid hybrids for root growth, but their overall growth rate and mass are much higher than incarnate due to polyploidy.

I grow them all in isolation in separate pots. For this reason, and also so that they are mobile - to be moved to a room or basement for storage.
But it may be that the root growth of those polyploid hybrids in whose genes there are edulis may be less than incarnate, because they are better propagated by the stem than by the roots. That is my hypothesis.

Just my limited experience, but the ones I grow, which are maybe 50% incarnata at most, probably a bit less, do sucker. They don’t sucker as much as pure incarnata though. The other parents would make a difference for sure, I think tucumenensis is somewhat herbaceous whereas edulis isn’t, so intucu hybrids would probably sucker more than edulata hybrids on average if I had to guess.

The seeds from @Vitamin have been inspected by USDA and have arrived. I will follow up with those who reached out prior to distribute. I kindly ask all those who receive them to try their best to document successes and failures and make the seeds available for sale and trade to improve the genetics of this crop. Thank you again Roman!

If you are interested in seeds and have not received a message, please message me and I’ll add you to the list. Thanks!

Also if anyone wants help to legally import seeds from outside the US into the US, I can provide some advice on the steps.
