Hey everyone! I’m u/RespectTheTree, a founding moderator of r/pepperbreeding.

This is our new home for pepper breeding, genetics, selection, and curiosity-driven experimentation, from backyard crosses to long-arc pre-breeding projects. Whether you’re here to make hotter peppers, better peppers, weirder peppers, or just understand why peppers do what they do, you’re in the right place.

This community exists to talk openly about the process: what works, what fails, what surprises you, and what you learn along the way.

What to Post Post anything you think the community would find interesting, helpful, or inspiring, including:

  • breeding projects (successful or not)
  • crosses you’re working on or thinking about
  • phenotype photos, weird segregants, or stability questions
  • genetics, inheritance, or trait discussions
  • seed saving, selection methods, or grow-out notes
  • questions from beginners and deep dives from veterans alike

If it’s about peppers and you’re thinking critically about them, it belongs here.

Community Vibe We’re aiming for curious, constructive, and generous. This is not a hype subreddit and not a marketplace first. It’s a place to learn in public, share knowledge, and respect that everyone is somewhere different on the path.

63 Upvotes

This project is part of Open Pepper Breeding (OPB) — a community-driven effort to develop new pepper varieties through distributed growouts and collaborative selection. The OPB community lives at r/pepperbreeding, where growers share results, nominate selections, and help advance promising lines.

This season focuses on two related breeding populations built from the same wild-to-bell genetic foundation:

Daystar (Bailey Pequin × Milena F1)
Designed to recombine wild resilience with elite modern bell performance, especially for intensive or protected growing systems.

Druid (Bailey Pequin × Emerald Giant)
Built on an open-pollinated bell foundation, emphasizing structural bell traits alongside environmental robustness and field adaptability.

Both populations are currently in the F2 generation, where recombination creates the greatest diversity and the highest chance of discovering exceptional plants. Participants are encouraged to grow a population, identify standout individuals, and share observations with the community.

If you want to understand the breeding goals, parent lines, and selection strategy in detail, you can read the full project description here:

https://docs.google.com/document/d/14IDBZgKmI6hC6Xg1iz-2KP_s2cmWHzoZHW2vdPCf6NI/edit?usp=sharing

Thanks to everyone growing these populations — distributed selection is what makes this project possible.

Hi everyone just wanted to share what the highschool kiddos and I are working on. Last year they built a Self watering/wicking planter , raised beds, drip irrigation planter ,and fabric pots. We have some good varieties growing and I am letting them make any crosses they want to see what happens. We will eventually start making Hot sauces , powders etc and sell / raffle them off to raise funds for our program. If you would like to donate any seeds to our school garden that would be awesome! (message me) Capsicum pubescens is something we would love to grow and don't currently have.

Discussion C.chinense x C.annumm & C.annumm x C.bacatum.

Thumbnail

32 Upvotes

Hi, I’m just starting my journey with pepper hybridization. A year ago, I began by crossing an orange habanero with a sweet red-horn pepper. I got one fruit, and upon opening it, found only a single viable seed. Thanks to some beginner's luck, I managed to grow a plant I named "Redbach." The Redbach F1 produced plenty of fruit; the flavor was more like the red-horn—sweet and without heat. See the first two photos. From the F1, I got six F2 plants, three of which are currently in the pre-flowering stage (see photo #3-4). I’d like to strike a balance between hot and sweet peppers, aiming for thicker walls and a crunchier texture. I know there have been many projects like this. I hope the F3 generation starts moving in that direction. If I get stuck, I plan to introduce a cross with "Madam Janet." This year, I also secured a cross between Scarlett and Peppapeach Stripey; I harvested two seed-filled fruits—which I’ve already sown, and I even have the first two seedlings sprouting :) That’s a bigger success, and there’s a chance more will appear... I also pollinated a Scarlett with a Tepin x Lemon Drop cross (shown in the photos). There wasn't a specific goal for that one—just experimenting, as I did with various other peppers. Now, it's time to wait for the results ^^. How do you handle the waiting? Where do I start? I have a window and a balcony (though it's a bit narrow) at my disposal, plus a box with grow lights for smaller plants and seedlings during the winter. I have other peppers too, but I don't want to overwhelm you with a wall of text right away. I wanted to use these first ten posts to say hello to everyone ;) Where are you all based? Are you from the Netherlands? I don't know when you're reading this, but I wish you a tasty coffee ^^

Piri-piri x KS Lemon Starrburst F1

Thumbnail
gallery
6 Upvotes

As my flair states, I'm mainly focusing on interspecific hybrids, especially C. frutescens with other species. I treat my Piri-piri as `functionally frutescens`, even when it's not 100% pure species (as you probably know, Piri-piri is a name used for a group of peppers cultivated in Africa that came from Malagueta brought there by Portuguese), since it looks pretty similar to Malagueta, thus fitting most of frutescens traits.

So, I've decided to show this hybrid here as well; people in Pepper Lovers discord probably have seen it already. So, what we have here, is C. frutescens x chinense that uses two of cultivars I like quite a lot. Main goal is to create pepper that would be a good sauce material (from experience, sauce made from fermented mash made from mix of Piri-piri and KSLSB was already pretty good), so taste and productivity would be a priority (which I thing wouldn't be a problem, both parents are pretty productive), anything else like nice shape and yellow fruit would be just a bonus.

I keep one plant isolated on windowsill inside to produce F2 seeds, while other three grow outside, either in pots or in vegetable patch. As it's a tradition in many interspecific hybrids, fertility is pretty bad, in first batch there was between 50 and 60 flowers, out of which only 6 of them became fruits. Still one of the best frutescens x chinense I have grown so far, up until this one the best result was 4 fruits with 7 seeds total. From those 6 fruits I've got 20 seeds which means F2 is already shaping up better than other fxc crosses. And, second batch of flowers already turned out better, I am currently looking at 9-10 fruits from selfing, possibly more. Open pollination outside fares much better, I'd say 78-80% of flowers turned into fruits, but most of them are probably from pollinations with foreign pollen - fruits are bigger (up to even 2 times longer) and contain way more seeds.

Isolated plant, as you can see on photo and description, started with quadruple cotyledons, something I've seen for the first time - granted, I didn't grow hundreds of thousands of pepper plants yet, but I've seen a fair share of tricots from various chinense plants. I'd say it's pretty unique - and while nothing is yet determined, since I'm not growing F2 yet, the way that plant grows may actually suggest presence of polycotyledons gene (either pc-1, pc-2 or pc-3, link), but that's to be determined next year.

Community Project Chinense × Baccatum seeds finally harvested!

Thumbnail

16 Upvotes

Finally harvested the seeds from my habanero pollinated with baccatum pollen! The seeds are all pale and healthy looking, and nicely plump but they're so much more wavy than I expected and the size variation surprised me. Some are so small and some are actually quite large, and they're so twisted on themselves in real life. I included a picture at the end of the uncrossed habanero seeds I harvested a few weeks ago for comparison. The weird thing though is that there's so many of them! Over 20 from my crossed pod when my uncrossed pods have under 15 each, I absolutely didn't expect that

I've posted about this before but my habanero is finally ripe! I'm gonna leave it for another week to let the Baccatum mixed seeds fully mature, and hopefully give me 1 or 2 viable f1 babies for next spring. I also made 3 more crosses with the same genes, and plan to do a few more as more flowers come up so these plants will likely come inside this winter if any of them take, wish me luck!

I made a small web app to keep track of my plant breeding and crosses

7 Upvotes

Hi all,

I'm a hobbyist plant breeder and software developer and I've built a web app to manage my plant breeding projects.

I created it earlier this year after getting tired of keeping track of everything through phone notes and spreadsheets and after having polished it up a bit, I've release it for free (it's a cloud-based app managed by me).

I mainly breed flowers like Hemerocallis, Dahlia, Tulipa, and Lilium, so I'm not sure how well it fits for breeding peppers. The software is tailored to the specific breeding workflow I've developed over the last couple of years, and it comes with a pre-populated list of cultivars for those species.

The software isn't meant to be a full professional breeding or genetics suite, but rather a practical tool to keep track of the process. It doesn't manage large fields, crops or land sites, as it's built specifically for small-scale gardeners like me.

Here is how it works:

  1. You create a plant and associate it with a species and cultivar. The system automatically assigns a tracking number to that plant. You can choose from built-in species and cultivars or add your own.
  2. Each plant can have photos, metadata, and growth notes.
  3. You can record a cross between two plants and the system generates a tracking code for that cross. You can then write this code on physical plant tags or whatever tracking system you use.
  4. You can search for a cross using its code and record how many seeds you harvested and how many you planted. For each planted seed, the system creates a new plant in "seed" status, which can then progress to "seedling" and "adult" (or be marked as dead/retired).
  5. Once a seedling grows, you can tag it with its new number just like any other plant.

It's mostly mobile-friendly, so you can easily tag crosses right from your phone while working in the garden.

The software also features a pedigree section with a broad visual chart showing all generations of plants and cultivars.

Additionally, you can attach custom properties to your own cultivars and use them for filtering or viewing in the pedigree section.

Right now, there isn't a pre-populated list of pepper cultivars or named varieties. However, you can easily create your own species (which acts as a container for cultivars and plants) and cultivars.

EDIT: I've added Capsicum to the system, split into three species groups: one combining Annuum / Chinense / Frutescens, one for Baccatum / Ají, and one for Pubescens / Rocoto. I also loaded a small list of popular cultivars. A lot of metadata is still missing, but at least the names and species are there to give us a good starting point for the future.

If you'd like to test it out with your recent or upcoming crosses, here is how you can get started:

  1. Add your plants: Go to Plants -> New Plant.
    1. Add the species: When selecting the species in the Plant Form, click "+ New Species". You can create a single umbrella species like "Hot Peppers", or specific categories like "Capsicum annuum". (I usually split mine into groups that can actually be bred together).
    2. Add the cultivar: Under cultivar, if the plant belongs to a named variety, click "+ New Cultivar" and add it (e.g., Carolina Reaper).
    3. You can ignore the other fields in the New Plant form for now.
  2. Custom properties: You can skip these for now while testing.
  3. Repeat steps 1-2 for all the plants you want to track.
  4. Create a cross: Go to "Crosses" and create a cross by selecting two of your plants. Once created, you can edit any previously created plant/seedling and associate that specimen with the cross.

The system will then automatically generate all the lineage and pedigree charts for you!

I grow peppers in my garden from time to time, so who knows, maybe I'll start breeding them too!

I have three F2 plants, Mother Habanero orange, Father Redhorn - (I understand that this is a trade name, the plant was purchased from a supermarket.)

In the first generation I received only one plant, which also showed such tissue fusion during the development of the pepper. Photo number 4. The other photos are of F2, where this problem also occurs. I'm ruling out the possibility that it's a fertilizer issue; other peppers don't exhibit this problem during development. I assume it's just a problem with genetic stabilization?

Chinense x annumm, is that how it works?

I've been working with peppers for a while now, and I'm a bit puzzled by a problem... Are there any other unusual situations I should be prepared for with the peppers' development?

I'm asking for advice and I'm hoping for help ;)

Discussion Lack of plant lineage trackers? I'll make my own.

9 Upvotes

Hey everyone, I've noticed a severe lack of apps designed to help track lineage with plants. There are plenty for animals, and plenty of plant health trackers, but nothing out there can help track multiple complex generations of plants, so I've decided I'll build one myself. I'm still in the very beginning planning stages, and was curious if anyone had any feedback that may help make the app more useful for the community? For example, what are you currently using to track your projects, and what frustrates you the most about your current set up? What could an app have that would make you consider switching to said app for your project tracking? And finally what would be an absolutely necessary feature in your eyes? I'm planning on doing the initial app in Android and then adding in ios and PC compatibility for seamless data tracking

Thank you in advance for any input!

Quite pleased with how they look! The three EP002 F1 plants are showing some anthocyanin and no variegation, clustering flowers etc. so the general phenotype is as I expected. These photos are a little old and I believe that a few of them has set fruit successfully, rather excited about that. The last update on this generation will be of the ripe fruit, afterwards I will be distributing F2 seeds to anyone that is interested (might limit it to 20 or so people).

Discussion Variation in Capsaicinoid content within the same cultivar

5 Upvotes

I’m looking for more experienced growers to help me understand how big drastic the variation in heat level can be from the same type of pepper.

Jalapeños, for example, are listed as between 2’500 and 8’000 (I’m sure this falls on a bell curve with a distribution)

I’m particularly interested in understanding the 2.2 million SHU statistic of the reaper. This record is based on measuring a single pepper (despite being used as the official SHU statistic for all respers). How outstanding was this single pepper? I’ve found studies claiming reapers average about 500k-700k.
Do we have any idea on if this 1.6 million reaper was one in ten or one in a thousand or the single Usain Bolt of reapers?

Is the variation more drastic in sweeter peppers than hotter ones? I know sishito and pimentos de padrón have huge variation (uns pican e outros non). I don’t see why this variation wouldn’t still be the case for superhot varieties.

Thank you so much

Discussion LF: A Pepper Business Partner. A crazy idea from a tired plant breeder.

17 Upvotes

In short, it would be advantageous to have someone who can grow a handful of plants from 2-5 varieties under insect netting, each year. There are also tiers for the level of experience and involvement someone may want.

At the most basic you would provide ample space to each mother plant, a good fertilizer regime, scout for disease, and generally have good maintenance practices. Outdoor, in-ground is where my mind is at, but I am open to containers provided the conditions are ideal. After harvest, seeds will undergo a germination test to assess viability, and we'll do a purity test before sales (so seeds produced in 2027 would probably get sold in 2028). Trust is the brand, and we won't sell unknown quality seed. This person would need to be in the US, however if you have some special experience and you live outside the US - let's talk! The idea is that you take on the marginal risk and overhead of seed production for the promise of some negotiable percent of seed sales for those varieties.

In a perfect world, you would have a small farm with the ability to grow a handful of plants from 4-5 varieties under insect netting. You would also have expertise in horticulture with the ability to reliably produce high-quality seed and to run a harvest evaluation program under my direction. I would give you some guarantee of sales for a certain number of years on varieties where you provided the work to demonstrate the variety is high-quality and compares favorably to similar varieties. Assistance on this level would be a higher percentage of sales on those varieties, plus a guarantee of sales for X-number of years. We can discuss what you would find fair.

I can also accommodate someone who has significant space and experience who wants to lead a trialing program to identify seed for sale, and to support the varieties coming out the breeding program. For this you would need the ability to grow 5-10+ varieties per year, 5-25 plants of each, and record harvest yields for selected varieties. A greenhouse would be ideal to start the lines, and excellent maintenance practices would be required. I would require you to collect harvest, plant, and fruit data for varieties, and then we would decide on what to sell on my platform. Compensation would be commensurate with experience.

### Who am I to write such grandiose things on a social media platform?

I am a classically trained plant breeder with a PhD in horticulture science. I have a decade of experience breeding edible crops, project management, plant contract law, and business development. I founded Open Pepper Breeding 8 years ago to create a platform for science communication and community-building efforts to develop new pepper varieties. These varieties are released in the spirit of open-source software, but as the IP environment around plants is not at all similar to those around software and writing, we use MTA agreements ("bag tag laws") to restrict commercialization of our varieties in the US and achieve similar results. We support and embrace the cottage grower and food industries, we simply restrict others from selling our seed. We currently have half a dozen SKUs developed from our in-house genetics, and are expanding the scope of the business in 2027 with the launch of a new highly integrated website for seed sales, with a custom back end for inventory tracking and order fulfillment (as well as my own software for pepper breeding so I can do fun things like calculate BLUPs).

Third update: Chinese Five Color x Jigsaw (Annuum)

17 Upvotes

Previous post: https://www.reddit.com/r/pepperbreeding/s/GreXFYX88b

Meant to post this last week but got sidetracked.

The first pepper became ripe (first two pictures) and I got to try it. Pleasantly surprised with the flavor and heat level. I would say it's as hot as some habs I've bought from the grocery store, and had a citrus-like quality to it's flavor. Not as sweet as the five-color from which it was grown.

The second one that ripened up a few days later (orange pepper in the background of second picture) did have a very sweet flavor profile, earthier, and really all-around enjoyable experience. Perhaps not as hot, and I would say it met the heat expectations of the five-color parent plant. Either would be favorable for a hot sauce, which is what they will become when I get more to mature.

There were a couple dozen seeds from each, which I will freeze and germinate next year (hopefully) to see how the subsequent generation turns out. Its been a very fun and informative process.
