breeding-crossing Superhot cross of carolina reaper and jalapenos.

Hello, I'm new to the forums here. I wanted to bring up a cross I came upon when growing carolina reapers and jalapenos in a community garden. I've been told that jalapeno crosses are very rare and seeds of a resulting cross don't tend to produce fruit. I guess I proved that wrong? The F1 pod I saved the seeds for were super hot with a knotty outside flesh of a reaper, but elongated shape of a jalapeno. The pepper flesh was on the thin side like that of a ghost pepper, and about as hot as a ghost pepper, but tasted almost exactly like a jalapeno.

With the idea that these crosses are rare, I saved the seeds and planted an F2 bunch of seedlings in my closet for the winter in small pots AND THEY GREW. I separated 1 of them and self pollinated it and then let the other 4 all cross pollinate each other freely. the self pollinated one, AKA Grouchy, flowered and grew pods the quickest. Grouchy grew larger pods of the same shape as the F1 cross, but it was MUCH hotter (comparable to a reaper). Grouchy pods had VERY thin knotty flesh with oozing capsaicin on the inside walls of the pod. Oddly though, the flesh of a Grouchy pod had a bit of a savory flavor and almost tomato like, but nothing like jalapenos. Grouchy pods also had NO spice for at least 10 seconds, and then BOOM immediate hit of heat to the back of the throat that lasted for a good 15-30 minutes.

2 of the other F2 crosses never grew flowers which I thought was odd, and then the other 2 F2 crosses left grew two different pods, I'll call them Vincent and Julius.

Vincent grew runt pods that were the size of a grape. Vincent's pods took FOREVER to polinate and took even longer to ripen, but also superhot with a floral flavor similar to reaper. Vincent, least attractive of the bunch, looked similar to the F1 cross, but was very similar heat level to the F1 cross, but had the flavor of a reaper.

Julius was similar to Grouchy, but grew the largest leaves, sprouted the quickest, grew tall very quickly, but the pods had very similar aspects to Grouchy's pods. The only real differences was the heat was even hotter with an immediate, longer lasting burn and a thicker flesh.

I don't really want to pay $60 bucks to get one of these tested for heat level, and also I want to find a stable hybrid before doing so anyway. I'm very new to cross breeding, but I've been gardening for quite a bit. Any advice would be greatly appreciated. I will take pictures of the plants in my closet with some of the pods ripening and a cross section of one of Vincent's pods for demonstration.

with my thumb as a guide to size, the smallest is from Vincent, the bigger green one is from Julius and the orange bigger one is from Grouchy.

Vincent sounds like a keeper.
I'm interested in the breeding project. They look hot AF.

What would you like for the next round of breeding?
Will you consider back cross to Jalapeno in the future?

Thanks for sharing, I will watching the grow
 
I don't think jalapeno crosses are rare, nor sterile. Maybe they were referring to crossing two different species (C. annuum and C. chinense), which is more difficult but still doable since they belong to the same clade.
To prevent cross pollination you always need to emasculate and isolate the flowers you pollinate. Then select for traits, 8 generations is a good goal for stability.
Sometimes plants differ from each other due to environmental issues, or because the starting seeds were not completely stable (open pollinated).
Good luck! 🙂

I didn't mention, but yes it is a cross between Capsicum Annuum Jalapenos and Capsicum Chinese Carolina Reaper peppers. I kind of wanted one round of open pollination to see what varieties I could get from the F1.

So after a plant has been self pollinated in isolation, are they not safe to mix in with other plants?

I plan on back crossing the F3s from Vincent and Julius with an F1 plant. Thanks for responding and keeping an eye out

Yes, I mark the self-pollinated (or hybridized) pod(s) then stuff the plant in with the rest to do what it will. Just mark your controlled pollination pods well so you can still identify them come harvest!

Thanks! Yes, I labeled them A thru E with A being the self-pollinated with bags pre labeled for those letters as F3 - A, F3 - B,... and so on. The pots have masking tape on them so I can reuse the pots for the next batch. I plan to plant these in a larger garden when the last frost comes and goes. That way I can start up an F3 batch in the closet and have Vincent and Julius to crossbreed with the new ones when they're ready to pollinate. I also decided to wait one more generation before back crossing with the F1 generation just to see if that iconic jalapeno flavor comes back without needing to germinate an F1 seed. Let me know if this is a good plan.
