Cold Hardy Citrus / Trifoliate orange
« on: September 18, 2022, 08:23:22 PM »
Trifoliate root stock in my dad's yard is disease free no greening or other disease. Other citrus in bad shape. Sugar bell is pretty good but not nearly like trifoliate. Fruit is not as bad as I thought though does have a faint weird taste that isn't good.

I wouldn't mind some seeds of some good hybrids. It seems everyone's hybrids on here are with other low quality cold tolerant citrus. If only satsuma or Meyer lemon or a tangelo like honey bell were in the mix.

Once you eliminate the off flavor being slightly bitter is not bad. Could make a lemonaid type drink. Or cross it with the Dunstan hybrid which tastes close to a grapefruit. Would be interesting most citrus here died but a few sour oranges and low quality types are healthy. Sugar bell is mostly healthy but not entirely but at least it has really good fruit.

The goal: grapes that are about as tough as native but better fruit qualities.

I have seeds left over from this spring.

Bd (stover x Daytona) selfed. I think it's bd5-115 I can't remember the numbers. I grew like 30 and have three. These don't grow very fast mainly due to inbreeding but the parent isn't a fast grower. Really low vigor due to inbreeding has thinned the herd. But once you cross it again vigor is restored.

This is a crisp non slip skin table grape green. It passes on pierce tolerance much better than anything else. Crossed with a non tolerant variety passes on full tolerance to 2/3 of offspring. Which it's like 15% with most hybrids. Overall disease resistance good considering. Some black rot. Everything seems to get rust in south Florida.

Should make good wine given the parents are good wine grapes. I have maybe 10 seeds.

Z86 x bd out of 25 I got about 3. One is insanely fast growing. One was decent I sold it. One runt I still have. Anthracnose and low vigor due to heat or whatever thin the herd. Everything usually still gets some minor black rot and rust among the survivors. But I have maybe 10 seeds left.

But here's this year's crop- (z86 x d370) x (shuttleworthi x aestavalis male)
This was sort of an accident. This vine bloomed this year at three years old. It was female and no pollinator. I got this wild vine that was blooming at the same time. Later than shuttleworthi and earlier than aestavalis.

Z86 x d370 has really good grapes and high disease resistance though black rot does build up and some rust. Not root nematode resistant in sand either. Everything else pretty good though berries were splitting.

So these seeds should be solid tough. But most will be male. No room to grow all these grapes. Males can be used as root stock or pulled up. I need someone that can grow some and keep me updated in two years send me a rooted female back. This batch the herd needs thinned out by cutting out males. All of them should be super healthy and disease resistant I imagine. For growing in Florida or the south.

Started in big pots with seed starter dirt they should grow super fast and get grapes in two years maybe one if you push it. Normal time is three years but these native ones when given the easy life can go blitzkrieg fast.

Need seed starter dirt due to it being neutral ph. In hybrids a lot of variability but generally they like neutral to slightly alkaline soil. Regular potting soil is too acidic unless amended. Anything weak can go in the trash but I doubt that will happen. This will take space to let them grow and get berries. Males just get pollen.

A normal hermaphrodite x female you get hermy and female offspring but with the wild male pollen lots of males.

Seeds need to go in a wet paper towel and in the fridge for three months for them to come up. Some don't come up the first year. Hence I start with 20 seeds, 15 come up, 12 die from disease is my normal path.

Aestavalis here has tiny berries. Edible but not great. Low sugar slightly acidic. Though occasionally some have good berries. But the aestavalis x shuttleworthi seems healthier than either one. Hybrid vigo. Aestavalis does have good cold hardiness and blooms later along with solid disease resistance. Though suceptible to insects eating the leaves. This is the only one in the mix with sub par berries and they are still edible.

Shuttleworthi pretty good eating overall some issues to be bred out through hybridizing. Main issue is super early blooming leading to lack of cold tolerance outside of Florida.

So we should get a tough female with pretty good berries. It should be as tough as a wild vine.

Tropical Fruit Discussion / Supremo Grape Breeding
« on: August 24, 2022, 02:33:15 PM »
Many years ago I noticed grapes growing in the woods in Florida. They actually were of decent size and tasted pretty good. Did somebody's back yard grape plant cross breed with a native? That was my first thought. I later found out these were entirely native grapes and the whole woods is covered with different species of grape here. Especially with muscadines they are literally weeds in Florida.

The best one is shuttleworthii- native to Florida only (not very cold tolerant because it blooms super early, which also minimizes the amount of cross breeding with other species). Somewhat small, but decent sized fruit. Dark red (burgundy) to light black in color. Excellent flavor, though slip skin and pulpy texture. Occasionally is a bit acidic depending on where it is at in the ripening stage (kind of gets acidic, then doesn't, gets acidic again, then less acidic)

Aestavalis has decent fruit, usually tiny in size here but some are decent sized. Some taste better than others. Sometimes has a bit of a weird aestavalisy flavor.

Muscadines are really variable. Some taste really good, some are slightly nasty but still edible, some are in the middle. Different from traditional scuppernogs- these are usually tiny berries, though some are a bit bigger, many have bunches here, and the flavor is a bit different. These south florida muscadines have been used a bit in breeding modern muscadine varieties, mainly for their bunching traits, though they can contribute thinner skin, or interesting flavors compared to traditional scuppernog.

I try to grow various domesticated grapes here and they all die from disease. Turns out florida with its high humidity and lack of winter has the most disease pressure for grapes in the country. I was fascinated with crossing shuttleworthii. Muscadines are a whole other species and too much for me to focus on- I have my hand's full with regular grapes.

I like to eat shuttleworthii berries when I can find them, and the plant itself has beautiful leaves. It's almost worth cultivating but I feel it needs to be crossed to get something a little more worth growing.

After trialing all kinds of varieties, cuttings and seeds, I finally got some seeds that produced viable plants for south florida. These were seedlings of Z86 (zehnder). This plant is about 6% muscadine, 8% aestavalis and about 85% vinifera. So the seedlings are about 3% muscadine- though there are no visible muscadine characteristics in fruit or leaves other than high disease resistance. Z86 is half cabernat suavignon. There are related varieties like z89 which is half ruby cabernet (known as Cabernet Zehn). I'm trying to get seeds of that.

I also tried Tari's Burgundy which seems to be half shuttleworthii, half vinifera, which did ok but had some disease and accidentally died- though it may be viable with some effort.

I got open pollinated z86 seeds the first year- mostly pollinated by D370 (dunstan 370). Dunstan has bred some amazing grapes. The first batch I lost a lot to animals eating the seedlings. Out of 30 I ended up with one winner. I had several that survived, but had some kind of disease susceptibility or not vigorous enough or whatever so I got rid of it.

z86 x D370 gave me fruit this year. The berries were slightly small, but decent size. About the same size as Concord or Shuttleworthii berries. Fruit was green (oddly) with a bit of a black tinge, though both parents were black grapes. Texture was not crisp, but melted in the mouth- very nice texture, much better than wild grapes, kind of half way between wild and a table grape. Skin did not slip off. Flavor tasted like a normal store grape. Bunch size was maybe not as big as a vinifera (store grape) but bigger than wild- pretty nice size bunches.

The plant takes a little black rot, and very slight rust, but overall pretty disease resistant and vigorous- though did not grow well in sand- I have them in big pots with potting soil and mulch now, though adding a small amount of sand seems to help them.

I have a z86 x taris selected out of about 21 seeds. Very fast growing- again slight blackrot, somewhat suceptible to rust. This one rust is a bit of a problem- but rust only occurs in tropical coastal areas so it should grow well in most places. Did not go dormat due to lack of hard freeze so no berries. The d370 x z86 goes dormat without any real winter, and my other taris x z86 also went dormat but it doesn't grow much in the heat so is much smaller.

I have a really fast growing healthy z86 x BD5-117 (stover x daytona) selected out of about 25 seeds. Again some really slight disease but overall healthy.

I have a possible shuttleworthii x seyval blanc but it looks like a shuttleworthii other than leaves being a bit thinner and seems somewhat sucpetible to rust in a way that shuttleworthii typically is not. I am always on the fence as to whether this is a pure wild grape or an actual cross. Will have to wait to get berries. I neglected it and planted it in the garbage sand and rock soil thinking it was a purely wild grape, but then my doubts started to arrise. I couldn't get any cuttings to root so its stuck there. It doesn't seem as drough tolerant as shuttleworthii, and struggles during the dry season, but seems to have no problem being completely underwater (which shuttleworthii tolerates as well).

I also have a possible seyval blanc or chambourcin x aestavalis. Again it seems strangely suceptible to rust, but otherwise looks exactly like an aestavalis. So again, I'm not sure if this is an actual cross or not. The aestavalis also planted in the garbage soil. It grows extremely fast.

Another mentionable is Lake Emerald. It has some of the best tasting grapes I have tried, and is highly disease resistant, though never produced grapes for me in south florida- did produce a lot in ohio. Seems not as well adapted to the heat, but very cold tolerant (strange because one parent is aestavalis native to florida).

And Suwannee is dong pretty well for me- fast growing, some small amount of disease but overall not too bad.

I have tried almost everything- pure vinifera like Thomson seedless- dead pretty quickly. Blanc Du Boise- did well in ohio other than leaves looking like swiss cheese from black rot, but after a few years, the winter got too cold for it and it died, though made it through several winters. In Florida it rotted and died pretty quickly from disease. Orlando Seedless- grew pretty fast for a while, then got covered in rust fungus pretty quickly. Concord- pretty disease resistant, but didn't do well in the Florida heat and didn't grow much. Ultimately a goner. Not pierce tolerant anyway (which is a disease issue in the south).

Caribe did pretty well but I neglected it and it dried out and died when I left in a pot and went up north. Ca8-15 (shuttleworthii x villard blanc) did pretty well but a late freeze killed it. Still trying to get this one again.

Tropical Fruit Buy, Sell & Trade / Tropical Grapes
« on: July 13, 2022, 12:40:44 PM »
I have really impressive rare tropical grapes derived from Dunstan and Zehnder.

I'm rooting some grapes and maybe sell some seedlings I have. I might wait until later in the year to sell them so it's not a big deal. Shipping is going to stress them. I will knock as much dirt off as possible and wrap the roots in a wet paper towel and if they are really big, cut them back before shipping.

z86 (a complex hybrid crossed with cabranet sauvignon) x Taris Burgundy:

Originally started with about 20 seeds two years ago. I have two selections that survived in south Florida. One selection was amazing. It grows extremely fast like a weed, and rare is that it grows in all directions (including vertically) so would be good for training (most hybrids grow straight up and try to reach for the highest tree top- this one eventually grew up but also grows side ways). Down side is thin canes which seem to come from shuttleworthii (long thin canes). But it grows so fast you can train it whatever way you want.

Seems to resist all diseases except rust and very light amount of black rot. Has a lot of rust here in coastal south florida which I spray for, though central florida, north florida and all points north shouldn't have any rust issues. Pierce tolerance I can't rate. It usually does not pass on well in hybrids so pierce tolerance could be moderate to high. Both parents have high pierce tolerance.

Berries: it's only two years old and seems to take three years to get berries no matter how big the plant is. This one didn't go dormant for me last year in Florida, despite temperatures in the upper 30s. It just kept growing. It grows when its 100 degrees out. It grows when its 40 degrees out. As long as it has water and nutrients it grows like a weed.

Based on the parents, and sister vine the berries should be really good for fresh eating or wine. Though the sister vine the sugar and acidity is a bit low for wine you can always add sugar and make adjustments to it.

It is more disease resistant than the parent "Taris Burgundy" which everyone brags about being one of the best vines for Florida. Taris did ok for me. It was not nearly as vigorous or resilient as this vine, and it had slight anthracnose and would have had rust too. But it struggled for me and then a dog chewed some of its leaves off and it died on me. Almost every grape variety I tried in south florida died on me. I got these seeds from someone.

Most of the seedlings I got from this cross, some grew fast but died from anthracnose. Some were resistant to anthracnose but weren't growing and didn't seem to like the heat and humidity. This was the one seedling that had the right combination of traits and took off. I had several that survived but weren't growing, all of them croaked except one. It remained a little baby the whole first year. Then this second year it went dormant (the one I'm selling didn't go dormant), then came back in the spring and is growing pretty well this year. But its not big enough for me to get babies off of it easily.

It seem to root easily. I bury a part of a vine in dirt (while its still connected to the mother plant) and it roots within a month or two and then starts growing like crazy and I cut it off from the mother and have a new vine. Some varieties I have did not root for me when I did this, but this one seems to root easily. It probably would root well from cuttings.

I have two of these I rooted. I can easily make more because it will just keep growing new shoots I can root. Though it does take some disease damage, probably better than anything else you are going to get.

Despite all the rumors and stories Tari's Burgundy does not appear to be a muscadine cross. It seems to be half shuttleworthii (native to south florida with good tasting grapes) and half vinifera. z86 is about 6% muscadine, 85% or so vinifera and the rest mostly aestavalis.

So this cross is about 25% shuttleworthii, 3% muscadine, and 6% or so aestavalis. Though z86 tastes like a vinifera, and the fruit doesn't have any resemblance to muscadine, so the native fruit qualities are mostly bred out.

z86 x D370 (dunstan 370):

This one is three years old and I got berries. Good non slip skin green table grapes (with a slight blush to them so greenish). Tastes about like a store grape. Leaves and plant resemble aestavalis. Resists all diseases. Some very light amount of rust and black rot. Also roots without a problem.

I just started to root two of them so this will take a month or so to get a good root system on the babies. It didn't grow much at all in the sandy soil so I put it in a giant pot along with all my other plants. Probably not resistant to root nematodes that occur in the sand. Grew kind of moderate slow at first but on the third year growing pretty fast.

D370 is primarily an aestavalis/vinifera hybrid distantly related to Suwannee. So this one is  65% vinifera (same amount as the taris cross) and 3% muscadine but instead of shuttleworthii has a decent amount of aestavalis.

Berries taste like vinifera, skin somewhat thick for a table grape, non slip skin, inside somewhat puply but melts in your mouth (not crisp like store grapes). Seeded but its easy to spit the seeds out. Should make good wine, juice or jellies as well. Not super sweet so may need to add a bit of sugar for wine or juice, though the taste is good and I want to cut back on sugar. No strong flavors, just mild table grape with a slight wine grape flavor.

z86 x BD5-117 (Stover x Daytona)

BD5-117 has better disease resistance than either parent, and passes on pierce tolerance better than just about any other hybrid. Berries are non slip skin, good table grape with slightly thick skin. Berries are a bit smaller than Daytona but still medium size. University of Florida's breeding program just ended up having a big mix up so this grape never got released. Then University of California used it to breed some California table grapes that are resistant to pierce disease but they stopped using it and are focusing on vitis arizonica crosses now.

BD5-117 also can be used to make a good wine. It has a higher percentage of vinifera than Taris Burgundy or D370, slightly more. It is about 12.5% shuttleworthii, along with rupestris, aestavalis and other things in the mix.

So similarly this cross will be 3% muscadine from the z86 side.

I have one seedling that started growing super fast, with really good disease resistance. It's less than a year old. So that is the one I will keep, then maybe next year I can root it. It has oak shaped leaves unlike all my other seedlings. I have two siblings that survived that aren't growing as fast but pretty healthy. I was thinking of getting rid of one of them because I have too many grape vines.

BD5-117 selfed:

I have a lot of problems rooting cuttings that people send me so I try to get seeds. Selfed seeds are not great, because they have lower vigor due to inbreeding. But out of about 25 selfed seeds I started I have four that are doing good. I have one that I think I like best. So I will need to get rid of some.

They have some rust susceptibility which pretty much every grape vine I have has some susceptibility to rust, which isn't an issue further north. Otherwise they seem totally disease resistant. They are growing slower than others because of being inbred and also BD4-117 is not a fast grower anyway but actually in absolute terms they probably grow at a normal speed. I just have a lot of hybrids that grow like weeds so they are slow in comparison.

I also have Suwannee which is growing fast but slightly more disease prone than my others. I tried to root it but the wind keeps blowing it out of its pot so I gave up. But these varieties are overall better than Suwannee, Stover, Blanc Du Boise etc. Suwannee does have large berries and I was hoping to cross it at some point. It does grow fast, but the disease susceptibility is slightly more than I want. Blanc Du Boise won't survive for me, as most varieties won't. Never had Stover but the BD4-117 is better than Stover anyway and is half Stover.

I was looking for $10 a plant, which much of that will go into shipping cost. Maybe do a postal money order or something which I can cash at the post office. Just PM me, but I'm not going to be in a rush to send these out because I need to let them get a little bigger before shipping them, except for one taris x z86 which is actually really big.
