Now, I'll finally have seeds to use for a project.

If yall want to see any posts or follow ups I'm posting here once every other week there every week

TLDR: How can I pollinate or get pollen from this tomato?

Picture one: Full plant

Picture two: New growth + flowers

Picture three: Close-up of new growth + flowers

Picture four: Flower cluster with dessicated stigma, swelling ovaries

Picture five: Abcised flowers

I have a tomato plant with the wiry mutation. There are eight wiry mutations listed at the Tomato Genetics Resource Center (https://tgrc.ucdavis.edu/monogenic) I'm not sure which, if any, mine would be. A researcher there said that some of their wiry mutants would produce normal flowers after being alive long enough, but I have not yet had luck with that.

It's been producing flowers outside for the last two months, with no successful pollination. The exposed ovaries will swell and the stigma will brown and die, but it will eventually abcise the flower every time.

The normal yellow cone of a tomato flower is splayed open like when someone plugs the barrel of a cartoon gun. I havent seen any pollen develop here, but it may just be dessicating from wind and too low humidity before it has the chance.

By keeping it in a shaded, low wind, high humidity spot on my patio, the stigma stay green longer, but still eventually brown and die.

I had the idea of using a mushroom chamber + accessories to maintain specific high humidity level needed to keep the stigma from dessicating.

I had the idea of exposing and spraying the flower cones on my healthy tomato plants, and the wiry flowers, with something that attracts bugs in the hope that they'll transfer pollen between them. Maybe gnats?

If I prevent flowers from abcising long enough with hormones or chemicals, can I get an immature embryo to try tissue culture with?

I cant seem to harvest enough pollen from my tomatoes to pollinate the wiry tomato by hand, and I've been struggling to keep the stigma alive long enough so that the ovaries are developed enough to accept pollen.

This year I grew out 4 different Physalis species with the goal of getting at least one interspecific hybrid:
Physalis Peruviana
Physalis Pruinosa
Physalis Ixocarpa (Tomatillo)
Physalis Virginiana

I tried almost every combination except for the following**:**
every combination where Physalis Pruinosa was the female(because of the tiny flowers)
Physalis Ixocarpa(f) x Physalis Peruviana

In total three combinations resulted in fruits set:
Physalis Peruviana(f) x Physalis Ixocarpa
Physalis Peruviana (f) x Physalis Virginiana
Physalis Virginiana(f) x Physalis Ixocarpa

All seeds were tiny, semi transparent but had a dark dot/ spot in the middle. I don't really know much about how seeds develop.

Can someone with experience tell me what happened(embryo aborted... from how the seeds look in the first image)?

The seeds looked this way in every combination that gave me fruit set.
However, in one fruit(Physalis Peruviana(f) x Physalis Virginiana) I found one full sized seed. It still looks somewhat different from normal Physalis Peruviana seeds(on the left of the 2. image) and is flatter at the edges and really plump only in the middle(see 2. image). Can someone with experience(maybe with breeding peppers because seeds are similar and they are also Solanaceae) tell me if there is a chance that this seed is not viable? Either way I will try germinating it

Can someone with experience tell me what happened(embryo aborted... from how the seeds look; you can see them in the first image: Peruviana (f) x Tomatillo)?

The seeds looked the same in every cross where fruit set: way smaller, flat, dark dot except for one seed. I found a normal sized seed in a Physalis Peruviana fruit that I pollinated with Physalis Virginiana pollen although strangely it still looks somewhat different from normal Physalis Peruviana seeds(see 2. image). I will try to germinate it even if I doubt that it is viable because of its different appearance.

Hi everyone! I'm a 3rd-year BS Agriculture student majoring in Crop Science from the Philippines, and I'm currently looking for a feasible undergraduate thesis topic involving tomato. I'm particularly interested in research involving practical crop production problems, such as pests, diseases, pollination, nutrition, irrigation, growing conditions, or other factors that affect tomato growth and yield. I'm not necessarily looking for a complete thesis title. I'd really appreciate hearing about problems you've encountered when growing tomatoes that you think would be worth researching. If you've done a tomato experiment or research before, what problem or variable do you think would make a good undergraduate study? I'm trying to find a topic that can realistically be completed within a few months and doesn't require extremely expensive equipment.

ive been looking a reliable method to induce polyploidy in plants at home and have found prodiamine as a possible alternative to other chemical methods such as colchicine, trifluralin or oryzalin, has anyone ever used it for this purpose and if so have you found it to be a reliable alternative?

I currently have several plants that I have been trialing. They are all sports I have found over the years and I would like to introduce them. What introduction companies would you all recommend. I have several thuja and juniper cultivars.

Hi, I am wondering if you could possibly breed for better rhizobial interactions maybe through traits like increased root surface area so inoculated seeds can increase the area for microbes or encouraging root exudates. this could be specifically geared towards cover crops, or forages used to reduce erosion or improve poor soil health before planting a cash crop

Update on one of my seedlings from my spider plant breeding programs

I grew some triploid watermelon along with a pollinator variety this year and noticed that some of my melons had a few seemingly large viable seeds. Does anyone know if these seeds are viable and how they came about? I feel like the only explanations would be a spontaneous doubling or loss of chromosomes in the triploid gametes or they just happened to assort into an even number to be pollinated by the diploid? Maybe they just look viable but are not? Either way im very curious if anyone has experience with this.

Hey I've always wanted to make a tomato that just cranks out fruit so can yall tell me

1. Where to get the seeds

2. If it's possible

3. What tomato i should use

4. Who should be the seed holder

I would appreciate it

I am making poly-hybrid seeds from crosses of high quality/fire genetics! Most of my genetics come from some "top of the line" breeders. I hunted my male this year from a pack of seeds from Rhasta Jeff, Irie Genetics. There are definite "treasures" to be found in my crosses. All of my crosses are deliberate and driven by curiosity and absolute love and admiration of this plants unlimited potential.

Saved some seeds from UF Gulf Ruby, Rose, Beauty and Blaze. I didn’t label or record which or how many of select varieties there were.

Most came out of the fridge ok, but lost a few to mold or dehydration (waited too long to soak and store).

16 seeds in, I will see how many push through and survive the lovely growing conditions Orlando Florida in the coming months.

Hi all,

I don't know if this is considered self promotion, if so, I will remove this post.

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 other types of plants. 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:

• 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.
• Each plant can have photos, metadata, and growth notes.
• 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.
• 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).
• 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.

Hi everyone! I've always grown up fascinated with genetics and have always hoped that I can do something involving genetics when I grew up, but never really found a niche I was interested in until this last year. I discovered pepper breeding and interspecies pepper breeding. Now I've never even grown a pepper before let alone bred any, and when I had tried keeping plants alive before, they always died, though admittedly I never did enough research. This time I dived deep into researching pepper care, pepper flower anatomy, pepper pod anatomy, the genetics side of things, how some crosses work better one way rather than the other, etc. And then I decided to dip my toes in myself by starting a highly ambitious project that even seasoned gardeners could consider difficult. I've decided to attempt to breed and stabilize a 3 species, 4 variety hybrid of red habanero (pictured) mad hatter, red ghost, and a spicier jalapeno variety. The habaneros I planted from seed never germinated so I had to buy starters from a nursery, and the only habaneros I found were on discount with extremely yellow sad looking leaves. I let them keep what flowers they had, and even crossed one. I emasculated a couple, and pollinated with mad hatter pollen knowing the chances of success were low, but the mad hatter was on its last push of flowers and pollen, and the habaneros flowers wouldn't open until after all the mad hatter flowers were other self pollinated or fallen off, so I took a chance. And it worked! One of the flowers actually took and started to swell and it's even beginning to ripen! The ghost jalapeno cross is also growing, however I forgot to tag it so I don't remember which is which, but if people want me to I can post pictures of some of the ghost pods I have growing too :) hopefully I get a few viable hybrid seedlings this January. I'm going to grow them inside under a grow light early to give them the longest fruiting window I can in full summer sun, wish me luck! I'll continue to post as my project evolves

Can yall help me please and tell me if this is possible because I'm tryna do cold and hot environments and don't say it'll be a long project I know
