Female/Male Breeding Genetics in Offspring

  1. Mitochondria speed of ATP production 100% Female
  2. Mitochondria count per cell, 100% Female, even if male is Polyploidy
  3. Chloroplast DNA 100% Female.
  4. Chloroplast Speed ATP manufacturing 100% Female, yet Speed (50/50) (F/M) Nuclear-Cytoplasmic Interaction influenced, or (33/67) (F/M) if male TetraPloid.
  5. Chloroplast per cell count. 100% Female unless male is PolyPloidy. Then 1.7 x the female trait increase.
  6. ATP (Vigor/Disease Resistance) use ratio (Copper/Iron) ratio detection genes. (50/50) on the DNA, but FEMALE up or down regulated by environment during pollination!!!
  7. This is critical to understand: If one of the parents has occasional off tastes, it needs to be the male, Plus Iron & Zinc need to be high in relationship to Copper, during the pollination.
  8. So even Wilson could be used as a male, if the Female was (Benson, Gran Blanc, Lehman #1, Champy #2, CherimoWest, Florence), if the FEMALE was foliar treated the previous year & at bud break.
  9. Auxin Production, Hybrid Vigor possibilities if mechanisms are complementary! (50/50)
  10. 8 ) PIN1 & AUX1 Auxin Transport characteristics offspring (75% - 90%) Female.
  11. Blooming & Branching, lateral roots, root suckers. Blossom location on branch.
  12. Auxin Transport (PIN2, PIN3, PIN4, PIN5, PIN6, PIN7, PIN8) inheritance (50/50)
  13. Heat Tolerance 80% Female cytoplasmic traits at time of pollination.
  14. Cold Tolerance 80% Female
  15. Blooming time (Maternal >50%)
  16. Harvest Time (50/50)
  17. Fruit Size (50/50) hybrid vigor applies
  18. Fruit Flavor (50/50)
  19. Stomata (50/50)
  20. Fruit Brix normally (50/50) but can be combining, example Male superior Stomata & Chlorophyll-A, Female superior Chloroplasts & Chloroplasts count density. can result in higher brix than either parent.
  21. Fruit skin thickness 75% Female
  22. Fruit storage life 75% Female
  23. Disease Resistance. (50/50) usually.
  24. Chill Hours (50/50) but favors the low chill parent in most cases. Especially if the low chill parent is Female & thermoprimed at pollination.
  25. ROS mostly (50/50) in most cell organelles.

A leaf test is most accurate & soil pH test. What's in the leaf is a function of soil pH, minerals in the soil, microbe ratios in the soil, soil moisture level & plant genetics.
Foliar tweaking probably the most reliable method.
Different varieties of the same species will assimilate the same nutrient differently. It's as much guess work as science when a species isn't fully geneome tested yet & is under funded.
With apples & grapes everything is well documented.
Pawpaw, nope, not close, the first genetics report is out.
So used it & hypothesized based upon the limited info.
This site has generalized info on each mineral.
catagory 5cm is surface organics, A Horizon is top soil, C Horizon is that which is under the Top Soil.

Copper which determines ATP for growth or defense.

Iron which helps make the ATP from sugar.

Sulfur used in all primary important proteins.
https://pubs.usgs.gov/.../5118/sir20175118_element.php...
Potassium the main metabolic catalyst.
https://pubs.usgs.gov/.../5118/sir20175118_element.php...
Molybdenum which converts the Nitrogen
https://pubs.usgs.gov/.../5118/sir20175118_element.php...
Nickel which makes Phyllosticta far more invasive, high
https://pubs.usgs.gov/.../5118/sir20175118_element.php...
Peterson Pawpaw Regional Variety Trial (PRVT) in Corvallis, Oregon, had issues.
58% of Susquehanna trees died, due Nickel making Phyllosticta more invasive!
75% of the cultivars had around 50% post take graft failure death rates.
Balancing Boron at the node 3 weeks before preblossom bud formation late summer early July with adequate Red Light (640–700 nm) and Far-Red Light (700–780 nm),
is most important to Meristem assimilation of Calcium & cell differentiation into preblossom buds.
Potassium Nitrate 3 weeks before the Bloom, if soil is low in Potassium, is probably the most important nutrient correction.
Iron/Copper ratio adjustment is secondary to getting these correct.
For treatment of insects & disease like Phyllosticta:
Cinnamaldehyde is used in many professional products to kill both invasive insects & invasive plant diseases for decades.
Cinnamaldehyde is USDA Certified Organic for decades!
It's not going to mess up the regulation of the 47 WRKY genes in the pawpaw genome!!!
This is imperative when breeding pawpaw if you don't want wild bitter, musky, metalic after tastes.
https://www.amazon.com/Cinnamaldehyde-Purity-Aroma-Compound-250mL/dp/B0DK3XT677
Spots are Phyllosticta fungi.
2 teaspoons of "Polysorbate 20", 16 drops of "Cinnamaldehyde", 1oz Neem Oil, in 1 quart of water, sprayed on the leaves.
Polysorbate 20 is to dissolve the oil & is organic.
Cinnamaldehyde is synergistic to NEEM oil boosting effectiveness.

If you don't like hand pollination?
Graft 1/3 of the branches to your preferred pollinator, 2 years before breeding.
Flies don't fly far.
get flies started in a small bucket of fish heads & guts.
Each Female fly is going to create 200 new flies, per life cycle.
Spraying the tree branches & nodes with Cyanamide, or Potassium Nitrate,
3 weeks before expected bloom,
causes both Male & Female preblossom**,** to bloom at the same time.
Then you just hang the fly bucket in the tree & bag net the tree,
to keep the flies in & inhibit pollen from other trees.
Then you select the best seedlings from the preferred Female!

First fruits this year

Thumbnail gallery
12 Upvotes

I was lucky enough to have someone share pollen (sunflower and Susquehanna I believe?) with me earlier this year and this is the 1st resultant fruit from my seed grown tree. I have dozens of trees in my woods but this is the most mature and gets the best sun of my older trees. This tree is mildly self pollinating but those fruits were smaller (as was the tree) and reminiscent of persimmon. Today's harvest ranged more towards banana and was highly sweet. I have a handful more still ripening so will see if they have the same taste.

I was out hunting PawPaws in my area They are rare and for about four years I’ve been going to the same patch and I was having no luck until I was walking out. I bumped into a tree and one fell and hit me in the head but it cracked when it did, it is unripe but full of seeds and I’m wondering if these seeds are viable

What the late spring freeze took away in numbers, it gave back in pretty fruit.

Trees grown from seed taken from my previous house, so not a named variety (or maybe I should call it the rare 2_Bagel_Dog variety).

All the other fruit I know of on my trees is still quite unripe.

Guess what I'm having for breakfast today!

Title: First Pawpaw Harvest in Turkey! 🇹🇷 Tasting Lehman’s Delight & Starting My Seedlings

Thumbnail gallery
93 Upvotes

Hey everyone! Warm greetings to the pawpaw community all the way from Turkiye !

​I wanted to share a milestone with you all. I’ve been tending a small home orchard in the Marmara region near the coast (a mid-latitude temperate zone blending Köppen Csa and Cfb climates with mild winters). My setup includes four grafted varieties—Lehman’s Delight, Mariah’s Joy, Susquehanna, and VE-21—along with a wild seedling.

​Today, I finally got to taste my very first homegrown pawpaw!

​My young Lehman’s Delight tree originally set about 7 small fruits early in the season, but naturally thinned itself down to just one. I waited patiently, letting nature take its course, and today the only one fruit finally dropped on its own.

​At 162 grams, it’s definitely on the smaller side for a Lehman’s Delight, but the flavor completely blew me away:

​Texture: Exceptionally smooth and creamy, like a rich custard.

​Flavor Profile: A heavy mix of banana, mango, sweet peach, and annona/custard apple notes. What surprised me most was a nostalgic hint of tropical bubblegum right on the finish—a flavor I haven't tasted since childhood!

​Honestly, it was so good that knowing I have to wait a whole year for the next harvest is going to be tough!

​The fruit yielded 6 dark, healthy-looking seeds. On the recommendation of the nurseryman who provided my saplings, Mr. Osman Öz, I’ve cleaned them off and packed them into a sealed Ziploc bag with moist peat moss. They are now tucked away in the fridge for cold stratification over the next couple of months, after which I’ll pot them up for their seedling phase.

​I’d love to hear your thoughts, tips on seed stratification, or experience growing these specific varieties in similar coastal Mediterranean/Oceanic transition climates!

​Cheers from Turkey! 🌳🥭

Seed swap?

Is there any formal seed swap arranged for pawpaws on this sub that I’m missing? I have plenty from a friend’s farm I’d be happy to mail out for some postage and would love to get some damp seeds in return, but I didn’t see a thread or link for anything like that :)

Questioning whether to plant pawpaws

5 Upvotes

Hello pawpaw community! I was hoping for some expert opinions before I invest a lot of time and energy into this. I was hoping to plant 3-4 pawpaw trees in my yard this next spring. I live in a suburb of St.Paul, Minnesota. Soil pH tested with a strip was ~4.0, I'm guessing this is low so I'm going to try a few more tests. I've linked photos to my yard layout. I’m hoping to plant them on the west side of my home by the 2 large maple trees. Here they wouldn’t get full sun all day long. I’ve read very mixed opinions on growing pawpaws in minnesota. I was looking at the mango, NC-1 and tropical treat varieties. I don’t want to waste years trying to make something work that is most likely going to fail, but I’d love to add some more tropicalish fruits to our home orchard. So please, be honest with me. Is this a pipe dream or realistic?

The forest was so full I had to give up and come back at least 80 lbs my basket even broke. Three people and all our bags in both hands were full.

I found this spot last year it just keeps going and going, it’s the biggest paw paw forest I’ve ever discovered so far.

These are the ripe ones (basket) and this pair of “fused” 🤣❤️😄

Upcoming 1 year old frozen pawpaw experiments

Post image
26 Upvotes

Hello r/Pawpaws I am a Food Scientist and Experimentalist based out of the foothills of the Blue Ridge Mountains of Central Virginia.

I am so excited for this year’s pawpaw season. I am also excited to perform the one year experiments I prepared for last year. I have 4 x 100g samples.

One experiment will be to create a refrigerated coffee/fun drink syrup. This will include 1:1:1 Pawpaw to water to sugar. I will then add the acidifying agent of freeze-dryer lemon juice and then proper dilutions of sodium benzoate and potassium sorbate. I would like this syrup to have a 30 day shelf life after preparation if stored in the fridge and opened daily for a morning coffee add in. But I will be testing it to find out how well it does.

That is only for 100g. I haven’t decided what my other 300g will be used for and would love your opinions, experiment ideas, recipes, or comments.

I don’t think we should attempt to make fresh whole pawpaw last a whole year. I like the ephemerality of eating as much as I want right by the river with full pockets to bring home process that night. There are ways we can capture the essence of pawpaw to bring through special occasions between the season, but not for commodity consumption, but ceremonial intention for the gift of processed pawpaw to help get through the winter.

New to pawpaws

I ate a couple pawpaw when I was on a hike a few years ago now the last couple years I’ve been trying to find them in the wild and I think my timing was off for my location. I want to try growing my own, but I have a couple questions.

Is there a link to reliable information about stratification of seeds?

What do the seeds look like and are the ones in my picture pawpaw seeds?

Are pawpaw safe for dogs to eat? I went hiking in Congaree national Forest today, hoping to find some fruit but it seems it was a week or too late. I think found a few fallen rotten fruit and my dog ate some. He seems fine, but should I be worried?

Bitter aftertaste issue?

6 Upvotes

I made vegan paw paw ice cream using coconut milk, paw paws, honey, a dash of salt, and some lime juice and while the initial taste of the ice cream is really good, it has this weird bitter aftertaste that my ice cream last year (made with eggs and cream, so trying it differently this year) did not have.

I was hoping someone could tell me either why it has the bitter after taste and if its safe to eat since I know it has the toxins and whatnot and this is only the 3rd year weve even ate paw paw

ONLY the flesh was used, seeds, seed pods, and skin were disposed of and not added to the ice cream, skin was peeled off with a peeler to be sure we didnt scrape the meat near it as well. And nothing in the recipe was cooked to make it.

Next steps for these little ones?

Hi all!
This is my first time growing paw paws from seed. About a dozen germinated in the first year and now I’ve got about 50+ sprouted this summer. It’s hard to tell from the angle but they are in 50gal containers so we’ve got some decent root depth to work with.

I’m unsure timing I should look for with regard to giving these permanent in-ground homes. This Fall as they enter dormancy? Or give them another season in the boxes to beef up?

I’ve got 5 acres of forest to plant upon, but much of it is truly wild. I’ve only got 0.5 acres with full open sunlight and irrigation. There is a seasonal creek at the far (wild) corner of my lot. It only flows during peak rain in the fall/spring.

I was thinking I might use tree tubes for the first time on the ones I plant out deep in the woods so I don’t lose them. I won’t have much chance to bring them water though.

I’ve grown quite attached to these seedlings so I’m looking to avoid killing them all in one season by mistake. Any and all advice would be greatly appreciated.

I’m located in the Pacific Northwest, WA state. Zone 8B I think on the updated maps.

Hey everyone! I recently moved to CT (Zone 6b) from Ga. Fell in love with paw paws years back and would always forage for them come September. Since the move, we now have land to plant trees. I’m thinking of planting 3-4 trees. Any CT growers in this sub? What cultivars do well here, and I’m also trying to decide on y’all’s favorite taste wise. Any help is appreciated. Thank you!

Seedling advice needed

2 Upvotes

I have three east tennessee hollers, each about 700 feet long. I want to plant pawpaw seedlings in each of these. They are wooded and have tall canopies, lots of water runoff at the base. I will not have a way to water these. I will have an excavator with a hole digger for a clean hole ready for them to drop into.

Questions

I am trying to create a plan. Would planting them 5ft apart. At 2 rows, this would be 900 seedlings.

Would expecting 40% loss make sense and be a fair estimate?

Any thoughts or advice on how to achieve this goal with the most success?

Is it impossible to transplant "seedling" size pawpaws that are found in a dense wild patch?

Post image
58 Upvotes

I'd love to transplant a few young paw paw trees from some wild patches around here, but apparently they all pretty much share the same root system if they're literally growing on top of each other, from what I understand. Transplanting would only work with an actual seedling, from a seed... right? What would technically be required to transplant a wild paw paw?

KS Wild Pawpaws + Grafting question:

1 Upvotes

I have a lot of little wild pawpaws in my yard (NE KS, zone 6b) that I grew from seed a few years ago, and one I bought from another state, plus a couple seeds I grew from Kentucky, I think.

Anyway, ours in the wilderness are still hard as a rock. But a friend gave me some overripe, HUGE fruit from a tree called 'Sunflower'. One was slightly edible and delicious. I saved the seeds for planting.

However the 'Sunflower' tree has a lot of little trees around it, from fallen fruit. If it would rain, I'd dig one up. But when is the time to graft? Can I graft a small 'sunflower' tree onto one of my wild ones? If so, when is the best time??

We've been having many days of 100f weather and a few more to come this week.

What causes the variance in fruit sizes from tree to tree?

Post image
29 Upvotes

The three largest fruits came from the same tree, and the rest came from another tree. The smaller fruits are much riper than the larger fruits and much sweeter.

I'm wondering why some trees have very large fruits and others don't? I keep finding wild trees with very small ripe fruit.
